INTRODUCTION

The PC4020 is a highly flexible and versatile control which
will enable the installer to meet the most demanding
security requirements. The heart of the system is the main
control panel, designated the PC4020, which is
connected to other system elements using common 4
conductor unshielded station wire. The main panel
processes signal information and communicating with the
monitoring station. The main panel is capable of
supervising 16 zones, any of which may be defined for fire
or burglary applications and also manages up to eight
separate and fully independent partitions, assigning
zones and their controlling keypads in accordance with
installer programming.

The basic 16 zone capability of the PC4020 can be
expanded using either PC4108, PC4116 or PC4164 modules
which provide 8, 16 or 64 zones of additional inputs
respectively up to a system maximum of 128 zones. The
PC4108 and PC4116 are designed for use within any of the
cabinets and are shipped as PC boards only. The PC4164 is
designed to be placed inside the supplied cabinet.

Programming and system operation are carried out using
the LCD4500 liquid crystal display keypad. The LCD4500
connects at any point in the system to the four wire
communication bus or “Combus”, its specific identification
being determined automatically in the process of installing
it. A maximum of 16 LCD4500 keypads may be used on
any one system regardless of size.

The PC4204 relay output module is available for
installations requiring additional power beyond the 500
mA supplied by the PC4020 main panel. This module
comprises a 12 volt DC power supply of 1.5 Amp capacity
and four 12 volt relays with form C contacts which will
provide switched outputs under any of the 35 options
available in the list of programmable outputs. The PC4204
connects to the Combus via four wires as with other
system elements. It requires a 16 -18 volt, 40 VA
transformer and a 12 volt battery. Up to 16 PC4204
modules may be installed on any one system. The
PC4204 is shipped as a PC board only.

The use of any power source other than a PC4204 to
repower the Combus will result in a system
malfunction.

The PC4216 low current module provides 16 separate
outputs. Each output may be programmed to operate
under the control of 1 of 35 options as listed in the
programmable options section of the installation manual.
Up to 8 other PC4216’s may be used to provide outputs
for graphic annunciator or similar devices for the
maximum of 128 zones. The PC4216 connects to the
Combus with four wires. A maximum of 9 PC4216’s may
be connected to a system. The PC4216 may be installed
in the main cabinet or in other cabinet options and is
shipped as a board only.

The PC4020 includes the capability of driving a serial
printer using the PC4400 serial interface module. The
PC4400 connects to the Combus with four wires. The
printer may be located up to 200 feet (60 meters) away
from the module. The PC4020 is also capable of
communicating to a DVAC network using the PC4400
serial interface module. The PC4400 is shipped as a
board only.

INSTALLATION
AND WIRING

When designing a security system with the PC4020 that
will be larger than 16 zones or have two or more Partitions
it is best to first lay out the system on paper. This will help
determine the total number of zones, additional expansion
and power supply modules and other system elements
that may be needed.

When the location of all points of protection is known the
location of the zone expanders can be made. You will find
that working from a plan, a layout will reveal the most
economical use of system modules; two eight zone
expansion modules instead of one sixteen zone, for
example, can save long wire runs because of the location
of zones.

The plan will also enable you to make the most efficient
layout for the communications bus (Combus). This is the four
conductor cable which can be standard station wire (four 22
AWG wires colour coded red, black, yellow and green) to
which all system modules are connected in parallel. It is not
recommended to run the Combus in shield unless it is being
run through an area of high electrical noise.

The Combus may be up to 1,000 ft. (300 m) from the main
board to the farthest module, with any number of modules
in between. More than one Combus of 1,000 ft. (300 m)
can run from the PC4020.

Note: Do not use shielded cable for Combus wire runs.

Suggested Wiring Procedure

The first step in designing a PC4020 installation is
developing a system layout on paper. Doing this will allow
you to work from a plan and help to avoid making
mistakes and make programming easier.

Creating a System Layout
1 Draw a rough sketch of the building(s) layout in the

installation including the interior walls. Indicate on the
diagram the location of the PC4020 main panel. The
panel should be in a dry, secure location close to a
non switched AC source, a ground connection and a
telephone line connection.

2 Indicate on the diagram the location of all zones as

well as the device required such as smoke detectors,
motion detectors, door contacts etc.

3 Zones may be grouped together into partitions.

Knowing the zone number of each zone will allow the
partition setup done without mistakes. Locate any zone
expansion modules (PC4108 or PC4116) required
close to groups of zones for easier wiring.

Decide on the order to enroll the expansion modules.
The first 16 zones (1 through 16) are on the main
panel. As each module is enrolled it will be assigned in
sequence the next available group of zones. If an 8

zone module (PC4108) was enrolled first, it would be
assigned zones 17 through 24. If then a 16 zone
expansion module (PC4116) is enrolled it would be
assigned zones 25 through 40.

Once the order to enroll the expansion modules has
been determined, number each zone accordingly.

4 Wireless zones (used with the PC4164) can be placed

anywhere within the reception range of the PC4164.
Once the zone that are planned to be used are
indicated on the diagram the location of the PC4164
can be shown as well. For best results the PC4164
should be placed in as central of a location as
possible. Indicate next to the zone, the serial number of
that zone. This will make placement tests easier.

5 Indicate each partition by boxing the area of the partition

on the diagram. From this diagram it can be quickly
determined which zones belong to that partition.

6 Determine the number of keypads (LCD4500) required

for each partition and their location on the system. The
maximum number of keypads on a system is 16. Each
keypad on the system assigned to a partition can only
be used to operate that partition. (EXCEPTION - A
System Master or a multi-partition access code can
access any partition that the code is assigned to from
any keypad). Indicate on the diagram the location and
the partition each keypad will be assigned to.

After the number of zones, keypads, and their locations,
expansion modules and separately controlled systems
(partitions) have been determined, decide other
modules required to complete the installation.

7 The ESCORT4580 (Voice Prompting Module) is a

module which is connected to the Combus and the
Telco lines of the control panel. This module uses the in
house telephone(s) to give the user access to any
partition the users code may belong to. The module
may be enrolled as a Partition or Global unit.

Note: The ESCORT4580 is located in the Main
Cabinet with the control panel.

8 Siren outputs can be programmed to activate if one or

more partitions go into alarm. The main panel provides
one output (The Main Bell Output).

Additional outputs can be obtained from the PC4204
power supply/relay output module(s). Each PC4204
module has 4 form “C” relays, the last 3 of which can be
used as any one of the 28 output options (See PGM
Output List). Indicate on the diagram the location of each
of the sirens, and the location of the PC4204 module(s).

3

9 The PC4216 module provides up to 16 programmable

outputs. Each output can be programmed for 35
different options (See PGM Output List). It is also used
to display zones/status on a graphic annunciator. Each
of the 9 PC4216 modules is capable of being
programmed in any of the 25 available ways indicating
the location of the PC4216 and the module number
and also the module output option programmed.

See “PC4216 OPTIONS” for a list of the programming
options.

10 Indicate the location of the PC4400 serial interface

module on the diagram. The PC4400 provides serial
output to an on-site printer that will record the identity of
the system, description of the occurrence (alarm, trouble
etc.) by user, with date and time stamp. The PC4400 may
also be used to connect to a DVAC network allowing the
PC4020 to communicate to a DVAC receiver.

11 Mount the cabinet, panel (See “Mounting The Panel”)

and prepare the wires for connection to the panel.

RF Zones — Summary

Placing Components

Before permanently mounting components, each
component should be tested in its intended mounting
location to ensure it can communicate properly with the
PC4164. It is recommended that the Module Placement
Test is performed more than once for each zone.

For the best system performance, it is suggested that the
PC4164 be mounted in as central location as possible and
as elevated a location as possible.

In most installations, selecting a central location for the
PC4164 will ensure reliable system operation. When
mounting the PC4164 in a basement, it is recommended
that the PC4164 be mounted as high and as close to the
underside of the first floor as possible.

“***fair***” and the keypad will beep twice indicating
that the placement was fair. A fair placement result
means that the zone was placed in a location that has
passed the module placement test.

• Poor - This result will be displayed on the keypad as
“***poor***” and the keypad will beep three times,
indicating that the placement was poor. A poor
placement result means that the zone was placed in a
location that has weak RF transmission strength and
should be relocated. In most cases, moving the zone a
short distance from its original intended location should
correct the problem. After relocating the zone, repeat
the module placement test. When the test results are
satisfactory, continue with the next zone to be tested.

NOTE: To perform a module placement test on an RF
PIR motion detector, the zone must be tampered then
restored instead of opened then closed.

Wireless PIR Motion Detectors

To prolong battery life of a PIR Motion Detector, the
detector features a High Traffic Shutdown Mode. If a
motion detector is activated more than once within a 6
minute period, the detector will temporarily delay reporting
activity to the PC4164. The Motion Detector will then
require a 12 minute period of no activity before it will
resume transmissions to the PC4164. Because the High
Traffic Shutdown Mode prevents Motion Detectors from
being tested during a regular walk test, the Motion
Detector features its own built-in Walk Test Mode. To
activate this mode remove the back plate from the
detector to be tested, and then reattach it. The Motion
Detector will be in Walk Test Mode for 90 seconds. The
LED will come on for 3 seconds each time the detector is
tripped. (Note: The zone will not transmit the zone trip to
the PC4164 during this mode. To perform a walk test of
the Wireless PIR the zone must be tampered and
restored). At the end of the 90 second period the Motion
Detector will return to normal operation.

Module Placement Test

This section will determine if the location of a zone is
good. Once this section has been entered, the panel will
then prompt the installer to select a zone to be tested. Use
the [<][>] keys to scroll to the desired zone. Press the [✱]
key to select the zone. The keypad will now display the
message “Please Activate Zone”. When this message is
displayed open then close the zone from the intended
mounting location. The keypad will display the result of
the module placement test (with respect to RF strength).
Placement results are as follows:

• Good - This result will be displayed on the keypad as
“***good***” and the keypad will beep once indicating
that the placement was good. A good placement result
means that the zone was placed in a location that has a
strong RF transmission strength.

• Fair - This result will be displayed on the keypad as

Zone Supervisories

A zone supervisory is a transmission sent from the
wireless zone to the PC4164 as a test transmission to
ensure that communications between the zone and the
PC4164 are still present. When the PC4164 receives the
supervisory from the zone it will then transmit this
information to the control panel. If the control panel does
not get a supervisory within the "supervision time", the
zone will be considered lost and go into the open state..
(If Double EOL is being used the zone will go into the
Tamper Alarm state). If the partition is armed the zone will
go into alarm and transmit the sensor fault and alarm
reporting codes if programmed. The next supervisory that
the PC4164 receives for a missing zone will restore
communication with that zone and restore the Zone
Supervisory Fault.

4

Battery Troubles

If a zone has a low battery trouble, then that zone does
not report in with a zone supervisory within the
"supervision time". The zone will not go into alarm. This
has been included to reduce the possibility of a false
alarm from batteries that do not get changed in the zone,
and then the zone going into sensor fault.

Restoring Battery Troubles

A wireless zone battery trouble will only be restored after
that zone has been Tampered and Restored. This will
allow the batteries to be changed without multiple Battery
trouble/Battery restoral transmissions taking place. In
order for the batteries to be changed the cover must be
removed from the back plate (tampering the zone). When
the tamper is restored and the zone sends a battery
trouble restoral (as well as the tamper restoral) signal to
the PC4164, the battery trouble will clear.

Default Serial Numbers

Once this selection has been made the LCD will display
the message "Confirm Default Press ✱". To abort press
any other key. Once the [✱] key has been pressed the
LCD will display the message "Resetting ". All RF zone
signatures will have been erased from the PC4164.

Note: Deleting the RF signatures from the PC4164 will
not remove the zone(s) from the partition
assignment(s).

Combus Power and Operation

The PC4020 main board can provide up to 500 mA to
power modules, keypads and devices. A PC4204 power
module is required when additional current is needed
either for powering detection devices or operating bells
and sirens. The PC4204 requires its own transformer and
battery and can provide up to 1.5A at 12 VDC. Four relays
on the module provide form C switched outputs with
contact ratings of 3 amps @ 12 VDC (10 amps @ 120 VAC)
for a variety of programmable options. When used to
repower the Combus the PC4204 must be wired in
accordance with the instructions supplied with the unit.
Use of a power source other than the PC4204 power
supply module to supply additional power to the PC4020
system is not recommended for the following reasons:

If the main panel loses communications with a module,
within a maximum of 30 seconds the panel will perform a
system reset in which power to the Combus is removed.
Five seconds later power is reapplied and the panel will
attempt to communicate with the module. If the panel is
unsuccessful communicating with the module it will
display and report a Combus communications fault.

When the main panel performs a reset, relay 1 when
programmed for “Combus POWER” will open. This will
disconnect the power supplied to the modules, resetting
them so that communications to the main panel are
reinitialized.

For example, if the microprocessor on the module has
been scrambled due to a transient, the PC4020 will power
down the Combus, the PC4204 will mimic the PC4020 and
cut off its power supply to the module. The module will be
powered down. When the PC4020 returns power to the
Combus, the PC4204 will reconnect its power supply, and
the power to the module will return. Because the module
was powered down and powered up, the module is now
reset, and can communicate with the PC4020.

If a power supply other than a PC4204 was used, the
module would never power down, never reset, and the
module will stay off line requiring the attention of service
personnel.

CAUTION: When used to power a module, the “RLY 1
COM” terminal of the PC4204 must be connected to
the “RED Combus” terminal of the module only. The
positive (RED) conductor of the Combus must be left
unconnected to the module that is powered by the
PC4204. The “BLK Combus” of the module should be
run common to the negative (“BLK”) of the Combus.
Use of a power source other than the PC4204 power
supply module to supply additional power to the
PC4020 system is not recommended.

The Combus is a four conductor cable to which all modules
and keypads are connected in parallel. Connections to the
Combus do not have to be home-run. For example if a
storage building had an 8 zone expander (PC4108) and a
keypad (LCD4500) located in it, the zone expander and
keypad could be spliced together and run back on a single
4 wire cable to the nearest point on the Combus.

Testing The Combus

To test the Combus for a low voltage condition, connect
all devices to the system (include any motion detectors,
glass break detectors, etc.) and enroll each of the
modules. Exit installers mode and allow the system to run
normally for 5 -10 minutes. This will allow time for any
modules that may have battery troubles time to report. If
after this time there are any battery troubles be sure that
the batteries are "good" by disconnecting the suspect
battery and placing a voltage meter across the battery

5

leads (of the module); the output voltage should be 13.85
V. If the voltage is good then check the battery (under
load), even if the battery is under a load the voltage
should still be above 12.0 V. Once all (if any) battery
troubles have been taken care of, be sure that there are
no Combus Low Voltage troubles. If there are locate the
modules with the low voltage troubles by entering
Installers Mode and selecting Diagnostics. Refer to
Appendix B for the List of Diagnostics. Once the
module(s) have been isolated a PC4204 will be required
to increase the power to be module with the low voltage
trouble. Now that all trouble have been taken care of the
next step is to remove AC power from all modules and
allow the panel to run for 10 - 15 minutes on battery power
alone. If there are any Combus Low Voltage troubles a
PC4204 Combus repower module may be required at the
Low voltage location to insure proper system operation.
Repeat this test as required.

Mounting the Panel

Select a dry location close to an unswitched AC source, a
ground connection and a telephone connection for
mounting the Main Control Cabinet.

Remove the PC4020 printed circuit board, mounting
hardware, and keypad from the cardboard retainer inside
the large cabinet. Before attaching the cabinet to the wall,
press the five white nylon printed circuit board mounting
studs into the cabinet from the back.

Pull all cables into the cabinet and prepare them for
connection before mounting the circuit board to the back
of the cabinet. Press the circuit board down onto the
mounting studs.

There is room in the Main Control Cabinet (PC4001C) for
any two modules (PC4108, PC4116, PC4216 or PC4400).
Modules requiring power (AC and battery PC4204) must
be installed in the large Expander Cabinet (PC4002C).
This enclosure will accommodate one module (PC4108,
PC4116, PC4216 or PC4400) and a powered output
(PC4204) or any three modules. A small Expander Cabinet
(PC4003C) is available for a single module that does not
require external power.

Once the wiring is completed power the system up by first
connecting the battery followed by the AC transformer. All
LCD4500 keypads should display the message ‘LCD4500
DSC Ltd.’. Press a key on any keypad that is to be
assigned to Partition 1. The keypad will beep and display
the message ‘4500 Mod. #1' and the keypad is
automatically assigned to Partition 1.

Enroll every module to the system. Make sure you put
down the number of each module enrolled. Refer to the
Programming Manual for the required procedure.

When enrolling any PC4108 or PC4116 zone expander
module make sure to note the zones which you assigned
to the module.

This information is very important if it becomes necessary
to Add or Delete zones to or from a Partition. Zones 1
through 16 are assigned to Partition 1 by default. This can
be changed later in Installer Programming.

In Book 4 (Programming Work Sheets) you will find a
System Overview section. Fill in the information as each
module is enrolled. These sheets are designed to be left
in the panel so if future service is required, the location
and assigned number of each module will be readily
available.

Once all modules are enrolled perform a diagnostics
check on the panel to determine if any problems are
present (see “Diagnostics”).

Programming the System

The PC4020 has the capability to operate as 8 separate
alarm systems called Partitions. Dividing the panel into
Partitions will allow you to control access to specific
areas.

When the PC4020 is first powered up all zones on the
main board and User Codes are assigned to Partition 1. If
no other Partitions are required the entire system will be
considered Partition 1. This is important to keep in mind
as often in programming the panel will require you to enter
the Partition to program.

For example, when programming entry and exit times, you
must select the menu option ‘ADD/EDIT PAR’. The keypad
will then prompt you for the Partition to add or edit. You
must select Partition 1 for a system that has no additional
Partitions.

The factory default setting for all options is provided in the
Programming Work Sheets as well as programming
‘HOTKEYS’ for the option to allow quick programming.

Complete the Programming Work Sheets located in Book

4. Having this information prepared before programming
the panel will speed up the process considerably.

All information for the panel may be entered in the
Programming Work Sheets.
Any zone expanders on the system will include a similar
sheet and the information should be completed for
these as well.

There is no set order in which the panel must be
programmed, however, if you use the following guideline it
may simplify the programming of the panel for the first time.

Step 1 - Define all Partitions

When the panel is first powered up the 16 zones on the
main panel are assigned to Partition 1. Additional zone
expanders enrolled to the system are NOT assigned to
any Partition.

6

Any zones from 1 through 16 that are required on a
different Partition must be DELETED from Partition 1
before they are ADDED to another Partition. Any zones
above Zone 16 must be ADDED to the proper Partition.
See “Zone Assignment” in the Programming Manual (Book

3) for the procedure to add and delete zones.
When you ADD each zone to the proper Partition it will

save time if you also program the Zone Label, Zone Type
and Zone Options. All of this information may be entered
in the Programming Work Sheets located in Book 4 and in
the programming work sheet included with each Zone
Expansion module.

Note: Do not program any of the system outputs until
all partitions have been added to the system. All
output types that are selectable by partition will only
allow the choice of enabled parts.

Step 2 - Program the System

Now that the Partitions have been defined and zones
programmed, you are ready to program the rest of the
system. It is best to follow the Programming Work Sheets
starting at the beginning and carefully programming each
section. Having the required information entered ahead of
time will speed up this process considerably.

Once the Installer Programming is complete you can
program user functions ([✱][6][Master Code]). Next,
features on each partition can be enabled. Go to a
keypad assigned to the desired partition and enable the
features through [✱][6][Master Code] commands.

Step 3 - Program user Codes

From default the PC4020 comes with one user code
assigned as a Grand Master Code (‘1234’ for 4 digit
option, or ‘123456’ for 6 digit option). The other 127 user
codes, 4 digit or 6 digit, may be programmed by entering
User Programming Commands ([✱][5][Access Code]).
See ‘Programming Additional Access Codes Using a
System Master Code or a Supervisory Code’ section in
this manual.

Step 4 - Testing the System

See “Bell/Comm Test” under [✱][6] User Functions or do
the following. Contact the monitoring station to request a
transmission test. Plug the telephone cord into the RJ31-X
jack. If a DTS-1 is being used to monitor communicator
transmissions, connect it to the telephone line and place
the DTS-1 in the line mode by pressing the red “LINE/
LOCAL” button. Arm the panel, wait for the exit delay to
expire and trip a detector on an instant circuit. Wait for the
communication to complete. Disarm the panel and check
with the monitoring station to confirm acceptance of the
transmission. Perform additional transmissions required
by the monitoring station.

Check the “TROUBLE” light on the keypad. If it is on,
press [✱] then [2] to determine the trouble. The “Trouble
Display” section in “Keypad Functions” gives a
description of the different trouble conditions.

Step 5 - Instructing the End User

Describe system operation to authorized users.
Provide user with the instruction manual and instruct them

to read it to become familiar with the system operation.
Instruct the user to test the system on a regular basis as

described in the Instruction Manual. The Master Code
should be changed from the default setting and recorded.

There is a wide range of possible uses for the [✱][4] and
[✱][7] commands which are not described in the
instruction manual. Be sure to explain the functions of the
[✱][4] Sensor Reset and the [✱][7] Utility Output to the
user if they are incorporated into the system.

Hardware Reset of Memory to Factory
Defaults

If the Installer’s Code is lost through inadvertent
programming, the only means of reprogramming the
system is by a hardware reset. If the Installer’s Lockout is
enabled, there is no way to reprogram the system without
entering the correct Installer’s Code.

The PC4020 can also be reset through software in the
installer’s programming. See “Factory Default” in the
Programming Guide.

Note: Panels returned to DSC with the Installer’s
Lockout feature enabled and no other apparent
problems will be subject to an additional service
charge.

To reset the panel to factory default conditions:

1.Power the system down by removing both AC and
battery power to the main panel.

2.Short the zone 1 terminal and the PGM terminal on the
main panel.

3.Restore power to the main panel.

4.Wait for 20 seconds then remove the short between
the PGM and zone 1.

5.The system will have reloaded the memory with
factory defaults. All modules will have to be enrolled
again. The event buffer is the only part of memory that
is retained during a factory default.

TERMINAL
CONNECTIONS

This “Terminal Connections” section only refers to the
main board of the PC4020 system. Other connections are
shown in the module wiring diagrams.

“AC” Power Terminals

Use a 16.5 VAC transformer with a minimum 40 VA rating
to supply AC power to the PC4020. The transformer
should not be connected to an outlet that is controlled by
a switch. If AC failure occurs, it will be displayed as a
trouble on the keypad (see “Keypad Commands, [✱][2]
Trouble Conditions”). It can also be transmitted to the
monitoring station as a trouble condition (see
“Programming Manual”).

Auxiliary Power Terminals “AUX” and “GND”

The auxiliary power supply can be used to power motion
detectors and other 12 VDC devices. The “AUX” (positive)
and “GND” (negative) terminals provide 500 mA when the
PC4020 is used with one keypad. For each additional
module on the Combus, the auxiliary supply rating must
be reduced by the current rating of that module. The
auxiliary supply is PTC at 1 amp and a Main Aux Trouble
Reporting Code can be transmitted if the PTC fails. (See
“Programming Manual”.)

Programmable Output Terminal “PGM ”

The operation of the Programmable Output depends upon
which option is selected in the programming table. See
the Programming Manual for a list of options for the “PGM”
output. The “PGM” is a 3A (maximum) switch to ground. A
small relay, a buzzer or other DC operated device may be
connected between the “AUX” (positive) terminal and the
“PGM” (switched negative) terminal to interface with
controlled devices.

Combus Terminals
“RED”, “BLK”, “YEL” and “GRN”

Connect the red wire of the Combus to the “RED” terminal,
the black wire to the “BLK” terminal, the yellow wire to the
“YEL” terminal and the green wire to the “GRN” terminal.
The Combus is wired in the same manner on all modules.
The Combus is used by the main panel to communicate
with and supply power to the modules.

The Combus power supply terminals are fused
electronically (max. 500 mA with no load on AUX).

NOTE: When connecting modules to the Combus the
system must not be powered.

Zone Input Terminals “Z1” to “Z16”

Zone inputs “Z1” to “Z16” can be supervised End of Line

Switched Auxiliary Power Terminals

“SW AUX” and “GND”

The “SW AUX” terminal is positive while the “GND”
terminal is negative. The 500 mA auxiliary supply rating
must be reduced by any current taken from the switched
auxiliary supply which shares the same fuse as the
auxiliary supply. This output is fully programmable, but is
most commonly used with the “Sensor Reset” option,
allowing the user to control the switch from the keypad.
(See “Sensor Reset”.)

Bell/Siren Terminals

“BELL +” and “BELL -”

These terminals are for powering bells or other devices
requiring a steady output voltage on alarm. The bell
output is PTC at 2.5 amps. When connecting sirens
(speakers with siren driver already built-in), be sure to
observe the correct polarity. Connect the positive lead to
the “BELL +” terminal and the negative lead to the “BELL

-” terminal.
If no siren or bell is used, connect a 1000 ohm resistor

(brown, black, red and gold) between “BELL +” and
“BELL -”.

(EOL) resistor circuits, Double EOL circuits or normally
closed loops. If EOL are used, each input must be
terminated with a 5600 ohm EOL resistor (green, blue, red
and gold). An alarm condition will be created if a normally
open contact is used to short across the EOL resistor. A
trouble is created if normally closed contacts, wired in
series with the EOL resistor, are opened. See “Zones
EOL” in the Programming Manual. See the wiring diagram
for normally open and normally closed contact
connections.

If Double EOL circuits are being used, all zones will use
Double EOL resistors, except Standard Fire zones, Auto
Verify Fire zones, Delay Fire Zones, Links Supervisory
Zones, Links Answer, and Forced Answer zones. These
zones must only be connected using the EOL resistor.
Double EOL resistors allows the zone to be capable of
detecting zone tampers. The tamper resistor (5600 Ohm)
is placed across the alarm activating device, and the
single EOL resistor (5600 Ohm) is placed between the
alarm contact and the tamper contacts. This configuration
will allow the panel to detect Zone faults (zone shorted) ,
zone tampers (open zone), open zones (alarm condition
of 11200 Ohms), and restored zones (5600 Ohms).

10

If the zone is disarmed and the tamper (open) or fault
(short) condition is tripped a buzzer will sound from all
partition keypads for the length of Bell Time Out or until an
access code is entered. A zone tamper will be sent to the
monitoring station if programmed. See Reporting Codes
for details.

If the zone is armed and the tamper is activated, it will
transmit and log both the tamper alarm and the zone
alarm. There will be no buzzer sounded if the zone is
armed (unless the zone is programmed as a 24 hour
buzzer zone). See the “Control Panel Wiring Diagram” for
detail on the hookup procedure.

The type of circuit or zone definition (delay, instant, 24
hour, silent, audible, etc.) is programmed from the keypad
using the installers programming commands.

Telephone Terminals

“T IP”, “RNG ”, “ T-1” and “R-1”

The wires from the RJ31-X telephone jack are connected
to these terminals in the following way.

Note: For proper operation, there must be no other
telephone equipment connected between the
control panel and the telephone company’s
facilities.

Ensure that plugs and jacks meet the dimension,
tolerance and metallic plating requirements of 47
C.F.R. Part 68 Subpart F.

Battery Connections

Do not connect the battery or the transformer until the
wiring is complete. Connect the red battery lead to the
positive battery terminal and the black lead to the
negative battery terminal. If the connection is reversed the
battery PTC will blow.

SYSTEM
KEYPAD FUNCTIONS

Many of the functions in the PC4020 have limited access
so that only certain users may have control of special
functions. The installer can program the 2nd Master Code
to enable it and have access to the entire panel’s
operations the same as the Grand Master.

• System Master Code users can have access to all end­user options.

• Supervisory Code users can have access to options
related to their partition.

• All other types of users have options available to them
for their partitions.

All of the above mentioned keypad functions are listed in
the following pages.

Introduction

The LCD4500 remote keypad provides complete
information and control of the PC4020 control panel.

• The panel can be fully programmed from any keypad.

• The LCD display provides alarm and status indication
for the alarm circuits as well as guiding the user in
operating the system.

• The built-in buzzer lets the user hear correct key entries
and other alert signals.

• The 12 digit keypad is used for code entry and other
programming functions. All keypad entries are made by
pressing one key at a time.

The keypad is normally in the arm-disarm mode. In this
condition, the LCD message indicates the status of the
system. The “Enter Code to Arm System” message
comes on when all zones are closed. The system can be
directed to perform other functions such as zone
bypassing, displaying trouble conditions, displaying
alarm memory and programming by entering one of the
various [✱] commands described below. Pressing the [#]
key or not making any key entry for 2 minutes always
returns the keypad to the arm-disarm mode.

Partitions

The PC4020 can have up to 128 zones. These zones can
be divided by the installer into 8 separate partitions, that
can be armed and disarmed separately. Zones can be
assigned to more than one partition. Keypads can be
individually assigned as a global keypad or to a specific
partition. More than one keypad can be global, or can be
assigned to each partition. User codes can be enabled to
work on one or multiple partitions in the access code
partition mask. System Master codes can arm and disarm
any partition from any keypad. The default setting for the
PC4020 has only partition 1 enabled with zones 1 to 16
assigned to it. To enable more partitions, enter the Partition
Area menu of the Installer’s Programming section, and
select to add/edit the partition to be enabled.

Access Codes

An access code is a 4 or 6 digit (optional) number which
will permit access to the system, i.e. Arm/Disarm control,
Installer’s Programming etc. User access codes are
programmed in the User Programming section [✱][5]. The
default access code is ‘1234’ for 4 digit option, and
‘123456’ for 6 digit option. See ‘User Programming
Commands’ for details on programming access codes.

Partition Status Enunciator

Enabling the Full System Status Toggle in the partition
toggle options will display the current status of all
partitions on the partition keypads. This feature can also
be enabled on global keypads by enabling the Global
System Status Toggle in the system toggle options.

The keypads will display

Global Keypads

What is a Global Keypad?

A global keypad is a keypad which belongs to all
partitions. It can be accessed by all system users who
have a valid access code with the global access attribute
enabled. The keypad will prompt the user to arm or
disarm their partition(s). The global keypad can also be
“loaned” to a partition by selecting options from the global
menu then selecting the desired partition. The users can
only access partitions which are assigned to their codes.

Why should a Global Keypad be used?

Global keypads allow the entire system to be controlled
by one keypad. This is beneficial if the keypad is to be
located in a central area, for example, the lobby of an
office building where the zones are common to all
partitions and each office contains individual zones.

How to create a Global Keypad?

The global keypad may be any keypad on the system. The
first keypad on the system is enrolled as a Partition 1 keypad.
It may be made into a global keypad by selecting the option,
“KYPD #1 Global” found in the system toggle options of
Installers Mode. If multiple partitions are enabled on the
system this will assign the keypad to all active partitions.

When the next keypad is enrolled onto the system the
keypad will prompt with the message “Select (01) < >”,
options 01 - 08 are the usual partition assignments, the
last option (09) is “Global Keypad”.

System Master Code Functions

System Master Codes may perform any function for any
partition on the system except change or delete the
System Grand Master Code. Enter [System Master Code]
[9] to display the System Master Code Function Menu:

[0] View Event Buffer [1] Set System Time
[2] Set System Date [3] Enable DLS Window
[4] System Reset [5] Previous Menu

[0] View Event Buffer - This function allows any Master

Code to review the Event Buffer on the keypad display.
The first line of the display will show the event number
and the partition on which the event occurred; the
second line of the display will show the date and time
of the event. Press the [✱] key to display a description
of the event. Use the [<] [>] keys to scroll through the
list of events in the Event Buffer. Event 001 is the most
recent event and 512 is the oldest one.

[1] Set System Time programs the system’s 24 hour

clock. Enter 4 digits in 24 hour time to set the clock,
the first 2 digits are the hour, the last 2 digits are the
minutes. For example, to program 2:35 pm, type 1435.

[2] Set System Date programs the system’s calendar.

Enter 6 digits, the first two digits are the month, the
middle 2 digits are the day, and the last two digits are
the year. For example, to program Feb 14, 1994 type

021494.

[3] Enable DLS Window - The end user can enable ring

detect for 60 minutes to allow a computer to call the
panel. The installer can disable this function in the DLS
section of the installer’s programming.

[4] System Reset - A System Reset turns off the power to

the Combus for 5 seconds. No programming will be
lost and the time will not have to be reprogrammed. A
system reset should be done if there is a Combus
Communications fault or an Internal fault.

[5] Previous Menu - If the user decides to do nothing,

either select this option, or press the [#] key to return
to the arm/disarm menu.

Installer’s Programming Code

A default installer’s programming code “4020” is programmed
into the PC4020. This code is used with the [✱][8] command
by the installer to gain access to the system in order to enter
panel or communicator program information. The installer’s
program code may be changed by the installer.

Auto-bypass/Home-Away Arming

If a correct access code is entered and you do not exit the
premises, the system will, at the end of the Exit delay time,
arm with interior zones automatically bypassed if those
interior zones have been programmed as “Home-Away”
zones. These zones will remain bypassed until [✱][1] is
entered to reactivate bypassed home-away zones.

This is a convenience feature for the user who wishes to
remain on the premises with the system armed. The user
does not have to manually bypass the Home-Away zones.

To reactivate the Home-away zones that have been
automatically bypassed, press [✱][1]. This command is a
quick method of fully arming the system in residential
applications before going to bed.

Note: The auto-bypassed zones will only send a
tamper alarm when the tamper condition is activated,
using Double EOL resistors.

Partition Keypads

Arming

Close all protected doors and windows and stop movement
in areas covered by motion detectors.

The “Enter Code To Arm System” message should be on
the LCD display. The system cannot be armed unless the
“Enter Code to Arm System” or “Secure System or Enter
Code” message is displayed.

If Double EOL resistors are being used, 3 different
messages can be displayed when viewing open zones,
Zone Open, Zone Tamper and Zone Fault. Zone Open will
be displayed if the zone is in the alarm state (total resistance
between the zone terminal and common is 11200 ohms),
Zone Fault will be displayed if the zone is shorted, and Zone
Tamper will be displayed if the zone is open.

The “Secure System or Enter Code” message is used to
indicate to the user that a force armable zone is open, and
the partition can still be armed. After the partition is armed, if
the force armable zone is secured it will become an active
zone, and will cause an alarm if the zone opens again.
To program a zone as force armable, see “Zone Options” in
the Programming Manual.

Enter a single partition access code. As each digit is
entered the keypad will beep.

• If the access code was entered incorrectly, the
keypad will beep steadily for 2 seconds.

• If the code was entered correctly but the message
“Secure System Before Arming” is on the display, the
keypad will beep quickly followed by a steady tone.

15

• When the correct code is entered, the “Exit delay in
Progress” message will come on and the keypad will
beep quickly.

If enabled, a timer will appear in the right side of the
display indicating the remaining time in the exit delay. Exit
the premises through the designated exit-entry door. At
the end of the allowed exit time the message on the
keypad will change to “Enter Code to Disarm System”.
See the “Installer’s Programming [✱][8] Command”
section on how to change the exit time. Also see “Quick­arm” and “At-home Arm”.

If a multi partition access code is entered the keypad will

the 4 digit or 6 digit access code. If an error is made in
entering the code, press the [#] key and enter the code
again. The “Armed” light will go out and the keypad
buzzer will stop. The correct access code must be
entered before the allowed entry time expires. To change
the entry time see “Installers Programming Command”,
[✱][8]. If an alarm occurred while the panel was armed,
the “View Memory” message will be on the display with
the zone label for the zone that caused the alarm. The
display will keep those messages on for two minutes or
until the [#] key is pressed to return the panel to the
normal arm-disarm mode.

Zone Bypassing
[✱] [1]

A bypassed zone will not cause an alarm. If a zone is
bypassed the panel may be armed even if the zone is
open. Use zone bypassing when access is needed to part
of the protected area. Also, damaged wiring or contacts
on a zone may be temporarily bypassed until repairs can
be made so that the panel can be armed.

To bypass zones, enter [✱] [1]. An access code may be
required if the installer has enabled that option. A menu
will appear.

[0] Bypass Open Zones allows the user to bypass only
the open zones that are on that partition. Use the [<][>]
keys to scroll through the open zones. Next to the zone
label will the a [!] this character is used to indicate that
the zone is open. To select the open zone to be bypassed
press the [✱] key. A [✱] will appear next to the zone label
to indicate that the zone has been bypassed.

[1] Bypass Zones takes you immediately to bypassing
zones. Use the [<] [>] to select the zones to be bypassed
and press the [✱] key to select the zone. A “✱” will
appear beside the zone label to indicate the zone will be
bypassed when the partition is armed.

A zone search routine allows the user to find the desired
zone to bypass by entering in the first letter of the zone to
search for, and pressing one of the [<][>] keys. The [<]
key will search for the first zone on the partition that
begins with the letter selected. The [>] key will search for
the next zone on the partition that begins with the letter
selected.

the [>] key, the first zone that begins with the letter “R” will
then be displayed.

[2] Clear Bypasses removes all bypasses from all the
zones in your partition and then takes you to bypassing
zones. None of the zones will have a “✱” beside them.

[3] Recall Bypasses will bypass all the same zones that
were selected the last time zones were bypassed. This is
for users that are always bypassing the same zones.

[4] Previous Menu takes you back to the “Enter Code to
Arm System”.

When the PC4020 is programmed, the ability to bypass
certain zones may be eliminated. In this case, the “✱”
indicator for those zones will not come on in response to
the bypass command. Zone bypasses are automatically
cancelled when the panel is disarmed.

The installer can choose by partition if a code must be
entered with [✱] [1] to bypass zones. Only the zones
assigned to the same partition of the system as the
keypad can be bypassed. Only certain types of access
codes can be used to bypass (See [✱][5]).

Note: At no time can any armed zone be bypassed.

Trouble Display
[✱] [2]

The PC4020 continuously monitors a number of possible
trouble conditions. If one of these conditions occurs, the
keypad “TROUBLE” indicator will light and the audible
indication will sound (two short beeps every 10 seconds).
When the [#] key is pressed the audible indication will
stop, but the trouble indicator light will remain ON until the
trouble is cleared. Trouble conditions can also be
transmitted to the monitoring station. Press the [✱] then
[2] keys to display the types of trouble conditions.

Battery Trouble

can be reported if the battery is 11.3 volts or less,
disconnected or the battery fuse fails. Battery voltage is
checked once every 4 minutes, so the battery trouble may
not restore instantly when the battery is restored. Initiating
a bell/comm test will check the battery voltage. When DC
Inhibit Arm is enabled the panel will check the condition
of the batteries on the system (main panel and PC4204)
when an access code is entered. If during this check the
battery shows a low voltage condition the arming will be
inhibited. The LCD will display the message "Fail To
Arm... Battery Trouble" when this occurs.

The Control panel and each of the PC4204 modules may
only have 3 battery trouble alarms in a 24 hour period.
After the third battery trouble for a given module the
trouble condition will "Shutdown" until midnight of that
day. The trouble will still be enunciated with the keypad
Trouble LED but the event will not be logged to the event
buffer or be communicated.

AC Trouble

Fire Trouble ­trouble and a Fire Loop trouble transmission are
generated. A trouble on the FIRE loop will unconditionally
initiate an audible and visual (trouble light) indication on
the keypad. This means that even if any other previous
trouble has been silenced, a FIRE loop trouble will restart
the keypad buzzer.

Fire Trouble 2WS - If the fire zone on a PC4700 Fire
Module is opened, a visual keypad trouble (trouble LED
will come on) with audible indication and a fire zone
trouble transmission is generated. The LCD will show the
message "FIRE TROUBLE!! 2 Wire Smoke", until the fire
zone trouble is restored. If there is more than one PC4700

Sensor Reset
[✱] [4]

The Main Bell, Switched Auxiliary Supply and pgm
outputs can be programmed by the installer to be a
‘Sensor Reset’. (See ‘Sensor Reset’ in the programming
guide). This option allows the user to activate these
outputs from the keypad by pressing [✱][4]. The keypad
will display ‘Sensor Reset in Progress..’ and a countdown
timer will show how long the sensor reset will be active.
The Sensor Reset can be from 0 to 255 seconds, which is
programmed by the installer. (See PGM Pulse Times,
Utility/Sensor section in the Programming Guide).

Note: To perform a sensor reset from a global keypad
a partition must first be selected.

User Programming Commands
[✱] [5] [System Master Code] or [Supervisory Code]

The [✱] [5] [System Master Code] or [✱] [5][Supervisory
Code] command is used to program the Master Codes
and regular access codes.

The first access code is the System Grand Master Code.
Normally, only the installer can change the System Grand
Master Code. The installer may also program the system to
allow the user to change the System Grand Master Code.

Note: When using the global keypad the System
Master should assign access codes to prevent
duplicate access codes being used.

The System Grand Master Code has no limitations to its

use. It may be used to create or delete other System
Master Codes or to perform any user function on the
system. Note that only to the first access code can be the
System Grand Master Code.

Each access code may be programmed as one or a
combination of the following options:

System Master Codes may perform any function for any
partition on the system except change or delete the
System Grand Master Code, and change or delete other
System Master Codes.

Supervisory Codes allow the user to program and edit
other access codes, except System Master and Duress
codes, for any partitions the access code belongs to. It is
also used for arming, disarming, bypassing and all other
functions that a System Master Code is capable of.

Arm Only Code allows the user to arm only the partitions
to which the code is assigned.

Disarm Only Code allows the user to disarm only the
partitions to which the code is assigned.

Bypass Only Code allows the user to bypass zones on
partitions to which the code is assigned.

Door Strike Code allows the user to operate door strikes
only within the partition to which the code is assigned.

Duress Codes will send a duress code transmission to the
monitoring station whenever it performs a function. A user
would enter a Duress Code to indicate that they are forced
by an intruder to perform the functions on the system.
When a Duress Code is entered, the partition or partitions
to which it is assigned will function normally, and a Duress
Code transmission will be sent to the monitoring station.
Also, any outputs programmed as “Duress Outputs” will be
activated when the Duress Code is entered. A Duress
Code may be programmed for any functions except being
a System Master Supervisory or One-Time Use Code.

One-Time Use Codes are used to allow infrequent users
of the system, such as service personnel, to disarm then
arm the system. When the system is armed using a One­Time Use Code, the code will be erased once the Exit
Delay expires; after this time, the code may not be used
again. If the One-Time Use Code is entered before the
Exit Delay expires, arming of the system will be cancelled;
the One-Time Use Code may then be entered again later
to arm the system.

Log Only Codes are used strictly for logging to the event
buffer. The system master can log the time, date and location
which they were at with the Log Only codes. To enable this
code type, enable just door strike or disable all options.

4580 Access allows the user to access the Escort 4580
(Voice Prompting Module) via the in house telephone or
remotely through a telephone. The user will have the same
abilities through the Escort4580 as they would through a
regular keypad (See Programming Manual - Module
Hardware for more Detail).

Global Access allows the access code to be used on
global keypads. Disabling this toggle option for any
access code will inhibit the code from being used on any
global keypad.

Note: Quick Exit must not be enabled on UL listed
systems.

Auto Arm Control
[✱] [6] [Access Code] [2]

The Auto Arm Control options can only be accessed if
Auto Arm is enabled for the partition. The PC4020 can be
programmed to arm a partition at the same time each day,
by enabling the Auto Arm function and programming the
Auto Arm time.

At the selected Auto Arm time, the system will give a pre­alert. The keypad buzzer begins to sound and the Bell/
Siren will pulse once every 10 seconds to alert anyone on
the premises that the system is about to arm. The Bell/
Siren pulse can be disabled in Installer’s Mode.

The keypad buzzer will sound for one minute before Auto
Arming unless the Auto Arm is aborted. To abort the Auto
Arm and silence the keypad press any key during the pre­alert. The Auto Arm will be attempted at the same time the
following day. The PC4020 can be programmed to require
a code to be entered for a user to abort the Auto Arm.

Upon selecting the Auto Arm Control function, the Auto
Arm Control menu will appear on the LCD keypad.

(by the installer) for that partition. When this option is
enabled the partition will not follow the Auto Time
(programmed in section 2). For the Auto Arm Time to
function this option must be disabled.

[2] Auto Arm Time is the time the partition will
automatically arm itself every day.

[3] Sched. Disarm when this toggle option is enabled the
partition will follow the Autodisarm schedule programmed
(by the installer) for that partition.

Note: The Auto Arm time is a 24 hour clock and times
must be entered as two digit numbers.

E.g. HH - 00, 01,.....10, 11,.....22, 23

MM - 00, 01,.....35, 36.....58, 59

Enter 4 digits representing the time in hours and minutes
(HH:MM) based on 24 hour or military time. Always enter a
leading zero where only one digit is required, 8:05 am would
be entered as 0805, 1:30 pm would be entered as 1330.

Note: The panel will not autoarm, schedule arm, or
schedule disarm, if there is a loss of time trouble
present on the system.

Keypad Setup
[✱] [6] [Access Code] [3]

This function allows the user to adjust the backlighting and
contrast of each LCD4500 keypad. When this function is

[✱] [6] [Access Code] [5]

The Door Chime feature is enabled or disabled on a
partition by pressing the [✱] key to toggle from “N” to “Y”
or “Y” to “N”. When the door chime feature is enabled,
any zone that has been selected as chimeable will cause
the keypad to beep 5 times each time the zone opens or
restores while the partition is disarmed (Note that Fire
zones and 24 hour zones are never disarmed, therefore
they can never chime).
See “Chime Function” in the Programming Manual to
enable a zone to use the chime function. While disarmed
zone bypass may be used to eliminate the beeping.

21

Special Messages
[✱] [6] [Access Code] [6]

This function enables 2 special event messages to be
displayed when one of the special events occurs.

The first message is “System Has Failed To Arm”. It will be
displayed if the user is unable to arm the partition after
entering a valid code (E.g. Because of activity on the zones.).

The second message is “Alarm Occurred While Armed”. It
will be displayed if an alarm occurred during the previous
armed period.

Note: The following messages will be displayed when
one of the special events occur regardless of what this
toggle option is set for.

The third message is "Fire Alarm !!! 2 Wire Smoke", this
message will only be displayed if the 2 wire smoke
detector on the PC4700 fire module goes into alarm.

The fourth message is "Fire Alarm !!! Waterflow Sensor",
this message will be displayed if the waterflow detector on
the PC4700 fire module goes into alarm.

Note: If there is more than one of these fire messages
to be displayed at once the messages will scroll one
every three seconds to the next message.

Once any fire alarm has been silence a message "Fire Bell
Has Been Silenced" will be displayed on the partition and
global keypads until the partition is armed.

The fifth message is “Sensor Reset”. This message will be
displayed when a sensor reset is performed.

The sixth message is “Utility output”. This message will be
displayed when a utility output is performed.

The seventh message is “Zone Tamper”. It will be displayed
if the zone is opened while using Double EOL resistors.

The eighth message is “Zone Fault will occur”. It will be
displayed if the zone loop is shorted while using Double
EOL resistors.

See “Event Messages” in the Programming Guide.

Note: The Zone Fault and Zone Tamper event
messages will only be displayed when Double EOL
resistors are being used.

User Call up
[✱] [6] [Access Code] [7]

This function must be enabled by the installer. When
selected, the panel will call the downloading computer.
The downloading computer must be waiting for the panel
to call before downloading can be performed.

Lamp Test
[✱] [6] [Access Code] [8]

This option allows the user to test the lamp output of the
PC4216. If the module is programmed to be included in
the Lamp Test then selecting this option will activate all
output on the module regardless of the programming.

Walk Test
[✱] [6] [Walk Test Code]

There are 3 different types of walk test modes, Local No
bell, Local Walk Test and Local + Comm Test.

[0] Local, No Bell will not sound the bell when a zone is
tripped and no transmission will take place for the zone
alarm. The zone alarms will be logged to the event buffer
and displayed in alarm memory.

[1] Local Walk Test sounds all Fire/Burg, Invert Fire/Burg,

Burg and Inv Burg for 2 seconds regardless of the zone
type tripped.

[2] Local + Comm Test will function the same as Local

Walk Test, but the programmed reporting code will be
sent with each zone tripped.

[3] Disable Walk Test Mode, either arm the partition or

enter [✱][6][Walk Test Code] and select ‘Disab Walk
Test’.

Note: When Double EOL resistors are being used
during walk test, a zone tamper and alarm will always
be logged/transmitted.

Utility Output
[✱] [7] or [✱] [7] [Access Code]

The Bell output terminals, switched auxiliary terminals or
any pgm terminals can be programmed for Utility Output
(see Utility Output in the installer’s programming guide).
Any output that is programmed for utility output will be
activated when the user enters [✱] [7]. See ‘Pgm pulse
times’ for programming how long the outputs are activated
and see ‘Util Req Code’ for programming whether a utility
output requires an access code to be activated.

Notes: Regardless of the time remaining for the Door
Strike, it will be deactivated at the end of the standard
exit delay.

To perform a utility output from a global keypad a
partition must first be selected.

22

Installer’s Programming Commands
[✱] [8] [Installer’s Code]

The PC4020 is completely programmed from the keypad
by using commands in the [✱][8] section. The commands
are described in detail in the Programming Manual.

Note:

DLS IN PROGRESSDLS IN PROGRESS

DLS IN PROGRESS

DLS IN PROGRESSDLS IN PROGRESS
LOCKOUTLOCKOUT

LOCKOUTLOCKOUT

will be displayed on the keypad when the downloading
computer is On-Line with the panel. Installer’s Mode
programming will be inhibited.

“At-Home” Arming
[✱] [9] [Access Code]

Entering [✱] [9] before the arming code, arms the panel
without any entry delay on the delay zones and bypasses
zones that are defined as “Home-Away”. This command is
used for arming the system while at home. Once the
panel is Armed in this mode, using [✱] [1] will remove the
bypass from those zones defined as “Home-Away” if they
have NOT been manually bypassed. The [✱] [1]
command, as used here, only removes the bypass from
zones that were automatically bypassed with the [✱] [9]
command.

The “Armed” light will flash to indicate the partition is “At­Home” armed.

Keypad Zones

There are three zones which can be activated from the
keypad. The alarm and restoral codes for keypad zones
are programmed using the [✱] [8] command.

Pressing the [F] key for 2 seconds activates a fire alarm.
The fire alarm sounds the siren/bell in a pulsed fashion.

Pressing the [A] key for 2 seconds activates a silent
auxiliary keypad zone.

Pressing the [P] key for 2 seconds activates a silent panic
keypad zone.

Programming for the [F], [A], and [P] keys for the global
keypad can be found under the System Toggle Options.
The global keypad will always send (if programmed) the
system area account code. The [F], [A], and [P] keys will
activate for all active partitions, any valid access code
from any partition may silence the alarm.

Note: See ‘KEYPAD TOG OPT’ in the Programming
Guide for changing keypad zones options.

Quick Arm
[✱] [0]

Entering [✱] [0] is accepted as a valid arming code when
the “Quick Arm” feature is activated. This command is
often used when individuals are required to arm the
system but not disarm it. This could be used with home
visitors in the case of a residential alarm or junior
employees and maintenance staff in the case of a
commercial alarm. See instructions in the “[✱] [6] User
Functions Command” section for activating the “Quick
Arm” feature.

Quick Exit
[✱] [0] When Armed

Entering [✱] [0] when the system is fully armed will allow
the user 2 minutes to exit the premises through any delay
zone without altering the status of the system if the “Quick
Exit” feature is enabled. After [✱] [0] is entered into an
armed system, one and only one delay loop may be
tripped. Any additional activity on any other active loop
will cause that loop to begin its alarm sequence. Quick
exit activation will be logged onto the event buffer.

23

PRINTER SETUP

Note: Do not connect a printer on UL Listed residential
fire alarm systems.

The PC4400 module is used for sending serial
communications through an RS232 port to a local printer
for on site monitoring of the PC4020.

All programming of the PC4400 is done through the
PC4020.
The printer can be located up to 200 ft. (61 m) away from
the PC4400.
An 80 character printer is strongly recommended.

Configuring the Printer

1.Serial interface

2.Baud rate = 300, 600, 1200, 2400 or 4800 (PC4020
default setting = 1200 baud)

Note: 4800 baud is only available on PC4400
software version 2.0 and above.

3.Parity = None

4.Character length = 8 bits

5.Auto line feed = Off

6.American/Canadian character set

7.DTR Protocol or XON/XOFF (by default the PC4020
sends DTR protocol)

The PC4400 comes complete with a DB-25 (male)
modular jack adapter, and a 6 ft. (2 m) six wire extension
cord. A longer extension cord can be used if required, up
to 200 ft. (61 m) maximum.

Power down the PC4020, PC4400 and the printer.
Connect one end of the extension cord into the PC4400,
and the other end into the DB-25 modular jack adapter.
Connect the DB-25 modular jack into the RS232 serial
port of the printer.

See the PC4400 wiring diagram.

Power up the printer, then the PC4020 and PC4400. If the
PC4400 is already enrolled and the printer is on line, the
PC4400 will begin transmitting to the printer.
Sample 1 is a printout from the serial printer.

Most actions on the PC4020 that require an access code
are logged to the event buffer, and are sent to the printer
(see Sample 2).

The partition labels, access code names and zone labels
can be changed in the PC4020. See “PAR NAME LABEL”
in the Programming Manual for programming partition
labels. See “EDIT CODE NAME” in the System Manual
under [✱][5] commands to program the access code
names. See “ZONE LABEL” in the Programming Manual
for programming zone labels. The printout will then be as
Sample 3.

The PC4400 sends events to the printer as they occur.

If the printer is off line or disconnected, the PC4020
keeps new events in memory until they are ready to be
printed.

When the printer is brought back on line, the PC4400 will
send the new events to the printer. If 450 new events
occur before the printer is brought back on line (450
events = 75% of the buffer), the PC4020 will send the “Buf
Near Full” reporting code to the monitoring station. (See
‘Maint Rep Codes” in the Programming Flow Charts for
programming the “Buf Near Full” reporting code). If over
600 events occur before the printer is brought back on
line, the oldest events will be overwritten.

The PC4020 contains an event buffer which stores the
last 600 events.
To print out the entire event buffer, enter the “Prn Entire
Buff” section in installers programming [✱][8][Installer’s
Code][3][0].
The printout will begin with the oldest event in memory
and end at the most recent one.

DOWNLOADING

Note: Downloading is not to be enabled on UL listed
systems.

Downloading is the use of an IBM compatible computer to
program the PC4020 system. The computer can be
located either on site, or communicate over the phone.

The DSC downloading package version 5.3 or later
supports downloading to the PC4020.

See the downloading manual for details on specific
capabilities and the “DLS” section in the PC4020
Programming Guide for programming DLS options.

Downloading over Phone Lines

Make sure the “TIP” and “RNG” terminals are connected
to the phone line. Program the access code and the panel
I.D. code in the PC4020.

The PC4020 panel can call the computer, or vice versa.
“Ring Detect” or “User enabs DLS” must be enabled for
the PC4020 to detect when the phone line is ringing, the
time the computer is calling the panel.

The number of times the panel allows the phone line to
ring before answering is programmable, and the default
setting is 8 rings.

If the panel calls the computer, enable “User call up” and
program the phone number of the computer. Initiate the
call by entering [✱][6][Master Code][7].

Downloading with an On-site Computer

Phone lines are not necessary to download to the panel if
the computer is at the same location as the PC4020. The
tip and ring lines of the modem can be directly connected
to the tip and ring terminals on the panel.

A DTS-1 must be connected to the lines and in the local
mode.
Program the downloading access code and panel I.D.
code.
Program a zone for “Forced Answer”. See “Zone Type” in
the Programming Guide. This zone is only meant to be
temporary, to initiate downloading. It can later be
changed back to the required zone type.
Make sure the access code and panel I.D. code are the
same in the panel and computer. A telephone number
must be programmed into the computer to initiate
communications, and any number entries are accepted.

Activate the computer to call the panel. When the
computer indicates “Dialing...No dial tone”, press the dial
tone button on the DTS-1 until the modem dialing the
phone number is heard. Trip the zone programmed for
“Forced Answer”. The panel will seize the phone line and
initiate communications with the computer. The computer
will then display the message “Connected to panel...” and
continue with communications.

The DTS-1 must remain connected to the phone line in
local mode during the downloading.

The TM1 or RJ31-X jack connects single wires into one
end, and a telephone cord into the other end. Although
this jack is not necessary, it simplifies the connection of
the PC4020 to a modem. If a TM1 or RJ31-X is not readily
available, use a telephone cord. Plug one end into the
modem, cut off the other end, and wire the green and red
wires into the TIP and RNG on the PC4020.

25

UL LISTED COMMERCIAL AND
RESIDENTIAL INSTALLATIONS

The installation requirements listed below must be met for
the following grades of service.

Grade A
Local

The installation must have a bell UL Listed for mecantile
local alarms (AMSECO MBL10B) with Model AB-12 bell
housing.

The digital communicator must be enabled.

Control of the Protected Premises

In order to have a UL Certificated system the protected
area is to be under the responsibility of one ownership
and management (i.e. one business under one name).
This may be a group of buildings attached or unattached
with different addresses but under the responsibility of
someone having mutual interest. The person of mutual
interest is not the alarm installing company.

Bell Location

The alarm sounding device (bell) must be located where it
can be heard by the person or persons responsible for
maintaining the security system during the daily arming
cycle.

Protection of the Control Unit

The local control and the local power supply must be
protected by one of the following ways:

• The control unit and audible alarm device must be in a
protected area which is armed 24 hours a day.

• Each partition shall arm the area protecting the control
unit and the audible alarm device power supply. This
may require duplicate protection armed by each
partition. Access to this protected area, without causing
an alarm, will require that all partitions be disarmed.

In all cases described above, the protected area for the
control unit must be programmed as not bypassable.

All Commercial Installations

• The entry delay must not exceed 60 seconds

• The exit delay must not exceed 60 seconds.

• The minimum bell cutoff time is 15 minutes.

Residential Installations

• The entry delay must not exceed 45 seconds

• The exit delay must not exceed 60 seconds.

• The minimum bell cutoff time is 4 minutes.

Programming

The notes in the programming sections describing the
system configurations for UL Listed installations must be
implemented.

WARNING Please Read Carefully

Note to Installers

This warning contains vital information. As the only individual in contact with system users, it is your
responsibility to bring each item in this warning to the attention of the users of this system.

System Failures

This system has been carefully designed to be as effective as possible. There are circumstances, how­ever, involving fire, b urglary, or other types of emergencies where it may not provide protection. Any
alarm system of any type may be compromised deliberately or may fail to operate as expected for a
variety of reasons. Some but not all of these reasons may be:

■■

■ Inadequate Installation

■■

A security system must be installed properly in order to provide adequate protection. Every installation
should be evaluated by a security professional to ensure that all access points and areas are covered.
Locks and latches on windows and doors must be secure and operate as intended. Windows, doors,
walls, ceilings and other building materials must be of sufficient strength and construction to provide
the level of protection expected. A reev aluation must be done during and after any construction activity.
An evaluation by the fire and/or police department is highly recommended if this service is available.

■■

■ Criminal Knowledge

■■

This system contains security features which were known to be effective at the time of manufacture. It
is possible for persons with criminal intent to develop techniques which reduce the effectiveness of
these features. It is important that a security system be reviewed periodically to ensure that its features
remain effective and that it be updated or replaced if it is found that it does not provide the protection
expected.

■■

■ Access by Intruders

■■

Intruders may enter through an unprotected access point, circumvent a sensing device, evade detection
by moving through an area of insufficient coverage, disconnect a warning device, or interfere with or
prevent the proper operation of the system.

■■

■ Power Failure

■■

Control units, intrusion detectors, smoke detectors and many other security devices require an adequate
power supply for proper operation. If a device operates from batteries, it is possib le for the batteries to fail.
Even if the batteries have not failed, they must be charged, in good condition and installed correctly. If a
device operates only by AC power, any interruption, however brief, will render that device inoperative
while it does not have power. Pow er interruptions of any length are often accompanied by v oltage fluctua­tions which may damage electronic equipment such as a security system. After a power interruption has
occurred, immediately conduct a complete system test to ensure that the system operates as intended.

■■

■ Failure of Replaceable Batteries

■■

This system’s wireless transmitters have been designed to provide several y ears of battery life under normal
conditions. The expected battery life is a function of the device environment, usage and type. Ambient
conditions such as high humidity, high or lo w temperatures, or large temperature fluctuations ma y reduce the
expected battery life. While each transmitting device has a low battery monitor which identifies when the
batteries need to be replaced, this monitor may fail to operate as expected. Regular testing and maintenance
will keep the system in good operating condition.

■■

■ Compromise of Radio Frequency (Wireless) Devices

■■

Signals may not reach the receiver under all circumstances which could include metal objects placed on or
near the radio path or deliberate jamming or other inadvertent radio signal interference.

■■

■ System Users

■■

A user may not be able to operate a panic or emergency s witch possib l y due to permanent or temporary
physical disability , inability to reach the de vice in time, or unfamiliarity with the correct operation. It is
important that all system users be trained in the correct operation of the alarm system and that they
know how to respond when the system indicates an alar m.

■■

■ Smoke Detectors

■■

Smoke detectors that are a part of this system may not properly alert occupants of a fire for a number of
reasons, some of which follow. The smoke detectors may have been improperly installed or positioned.
Smoke may not be able to reach the smoke detectors, such as when the fire is in a chimney, walls or roofs,
or on the other side of closed doors. Smoke detectors may not detect smoke from fires on another level of
the residence or building.

Every fire is different in the amount of smoke produced and the rate of burning. Smoke detectors cannot
sense all types of fires equally well. Smoke detectors may not provide timely warning of fires caused by
carelessness or safety hazards such as smoking in bed, violent explosions, escaping gas, improper storage
of flammable materials, overloaded electrical circuits, children playing with matches or arson.

Even if the smoke detector operates as intended, there may be circumstances when there is insufficient
warning to allow all occupants to escape in time to avoid injury or death.

■■

■ Motion Detectors

■■

Motion detectors can only detect motion within the designated areas as shown in their respective installa­tion instructions. They cannot discriminate between intruders and intended occupants. Motion detectors
do not provide volumetric area protection. They have multiple beams of detection and motion can only be
detected in unobstructed areas covered by these beams. They cannot detect motion which occurs behind
walls, ceilings, floor, closed doors, glass partitions, glass doors or windows. An y type of tampering whether
intentional or unintentional such as masking, painting, or spraying of any material on the lenses, mirrors,
windows or any other part of the detection system will impair its proper operation.

Passive infrared motion detectors operate by sensing changes in temperature. However their effective­ness can be reduced when the ambient temperature rises near or above body temperature or if there are
intentional or unintentional sources of heat in or near the detection area. Some of these heat sources
could be heaters, radiators, stoves, barbeques, fireplaces, sunlight, steam vents, lighting and so on.

■■

■ Warning Devices

■■

Warning devices such as sirens, bells, horns, or strobes may not warn people or waken someone sleeping if
there is an intervening wall or door. If warning devices are located on a different level of the residence or
premise, then it is less likely that the occupants will be alerted or awakened. Audible warning devices may be
interfered with by other noise sources such as stereos, radios, televisions, air conditioners or other appliances,
or passing traffic. Audible warning devices, ho wever loud, may not be heard by a hearing-impaired person.

■■

■ Telephone Lines

■■

If telephone lines are used to transmit alarms, they may be out of service or busy for certain periods of
time. Also an intruder may cut the telephone line or defeat its operation by more sophisticated means
which may be difficult to detect.

■■

■ Insufficient Time

■■

There may be circumstances when the system will operate as intended, yet the occupants will not be
protected from the emergency due to their inability to respond to the warnings in a timely manner. If the
system is monitored, the response may not occur in time to protect the occupants or their belongings.

■■

■ Component Failure

■■

Although every effort has been made to make this system as reliable as possible, the system may fail to
function as intended due to the failure of a component.

■■

■ Inadequate Testing

■■

Most problems that would prevent an alarm system from operating as intended can be found by regular
testing and maintenance. The complete system should be tested w eekly and immediately after a break­in, an attempted break-in, a fire, a storm, an ear thquake, an accident, or any kind of construction
activity inside or outside the premises. The testing should include all sensing devices, keypads, con­soles, alarm indicating devices and any other operational devices that are part of the system.

■■

■ Security and Insurance

■■

Regardless of its capabilities, an alarm system is not a substitute for property or life insurance. An alarm
system also is not a substitute for property owners, renters, or other occupants to act prudently to prevent
or minimize the harmful effects of an emergency situation.
