Section 2
Quick Start

This section is intended to help you determine if any problems exist with the system you are
about to install. Perform the steps below in the order shown here.

1. Wire a touchpad to one of the four-wire serial buses (SBUS). See Section 4.14 for more
information. (See Note below.)

2. Plug in the transformer and apply AC.

3. Hook up the battery.

4. The touchpad will initialize. Several messages, including the touchpad seria l number, will
display for approximately one second. When the message “482x Engaged” (x indicates
that the display would read 1 for a 4821, or 0 for a 4820) is displayed, it means the system
has booted up successfully. The default date and time is displayed.

5. Set system date and time. You may use the default code to test the system. See the instruc­tions on the next page for more information.

If you are able to set the date and time successfully , it means the sy stem is up and running.

6. From here you can send your programmable options to the panel, if you have programmed
them through the Model 5580 Upload-Download Software. (See Section 2.2.)

Note: To at tach a t emporar y touchp ad to th e system, you do not need to kn ow its se rial n umber. To per manentl y

attach any SBUS device, including a touchpad, you must enter its serial number into the system.

3.4.5 Anti-Passback Feature

The anti-passback feature prevents users from giving access to others by “passing back” their
access cards. In a typical anti-passback installation, users must “register” themselves by
accessing a door programmed as Entry when they enter the building. They will only be
allowed to leave from a door programmed as Exit. A user cannot access an Entry door twice

consecutively. The menu allows users to be “forgiven” (allowed access even if
they have not exited properly) and provides other anti-passback options. See Section 3.4.6.

Figure 3-8 below shows an example of anti-passback application. In this example, employees
enter through an anti-passback doors (must enter and exit through separate doors). The man­ager’s entrance is not an anti-passback door, allowing employees to come and go freely.

Note: The anti-passback feature must be enabled through programming. See Section 6.

4.10 AC Power Transformer

The Model 9227 is an external transformer that is included with the 4821/4820. The trans­former output is 18 VAC, 50VA and provides power and battery charging for the system. The
transformer plugs directly into a conventional 120 VAC unswitched outlet.

The earth terminal on the 4821/4820 main circuit board provides a convenient method for
connecting the 4821/4820 metal cabinet to an earth ground. (See Figure 4-6.)The earth con­nection is also used for increased transient protection on the telephone interface. All circuitry
in the Model 4821/4820 system is electrically isolated from this earth terminal on the 4821/
4820 main circuit board. There should be no connections to this terminal other than the earth
connection for grounding the metal cabinet.

4.11 Backup Battery Connection

The Model 6712 is a 12 VDC 7AH gell cell battery available from Silent Knight for use with
the 4821/4820. (Note that the battery does not charge when system power is off.)

A low battery trouble condition exists if the battery voltage drops below 10.2 VDC.
The nominal charging voltage is 13.65 VDC (range is 13.5 to 14.0).
This manual contains a worksheet for determining battery size. See Section 4.9.4 for more

information.

Note: If you are installing a battery in a system that has a tamper switch, an alarm may occur when you install

the battery (because the door must be open when power is applied).

4.12 4195 Auxiliary Power Supply Installation

Through its two 1.25A 12 VDC terminals, the 4195 provides an additional 2.5A of current for
accessory items. The 4195 also allows you to use two standby batteries to double t he time that
the system can function on battery standby.

Figure 4-8 shows the location of LEDs for battery reversal and output overload. It also shows
how to wire the 4195. If you are using the 4195 to power smoke detectors, connect the 4195
CONTROL terminal to the 4821/4820 +SMK terminal. For powering other types of devices,
connect CONTROL to +12V.

4.13 SBUS

Most modules available for use with the 4821/4820 connect via a four-wire serial bus (SBUS).
There are two SBUS connections that are referred to in this manual as “SBUS1” and
“SBUS2”.

Each SBUS is a four-wire serial bus containing two power and two data conductors. The
power conductors are identified as S- (system ground) and S+ (+10 to +14 volts). The data
conductors are identified as A and B. Lines A and B are a differential RS485 pair.

All modules connected on the SBUS can be located as far as 4,000 feet from the control panel,
if sufficiently large wire gauges are used for the power and ground connections. The voltage
drop on the wire run must not be more than 2.0 volts. (See Section 4.13.3 for specifics.)

Figure 4-9 is a general picture of SBUS connection points. Wiring for each SBUS module is
shown in the appropriate section of this manual or in the separate manual for the device.

Figure 4-9 SBUS Connection Points

4.13.1 SBUS Modules

The following modules connect to the 4821/4820 via the SBUS:

• Touchpads (Models 4421, 4860C, 4860R, and 4860Rx)

Note: 4421 cannot be used with the 4820 control panel

• Zone Expanders (Models 4815 and 4825)

• Status Output Module (Model 4880N-750-SDB)

• Serial/Parallel Module (Model 4824)

Figure 4-10 shows an installation making use of all SBUS modules available with the Model
4821/4820 system. (For simplicity, the diagram shows all modules connected to a single
SBUS, though in a real application you would typically divide modules as evenly as possible
between SBUS1 and SBUS2.)

4.14 Touchpad Installation

This section describes installation of a touchpad for basic system operation. For information
about how to install 4860C touchpads as input zones, see Section 4.15.5.

4.14.1 Touchpad Specifications

• When installed for use as an access control system the touchpad must be located inside the
protected premises.

• 24 touchpads/card readers maximum per system.

• All touchpads require four wires to operate.

• Maximum distance from the control panel depends on the number of devices attached to
the SBUS. See Section 4.13.3 for complete information.

• Maximum current draw: 90 mA

• Standby current draw: 48 mA

• Maximum allowed voltage drop for a touchpad wire run: 2V

• For best system performance, connect most touchpads to the same SBUS, either SBUS1
or SBUS2. (Connect all other SBUS devices to the SBUS that is not used by touchpads.)

4.14.2 Mounting Touchpads

1. Separate the top section from the rear mounting plate. Do this by inserting a small flat­blade screwdriver into the slot located on the bottom edge of the frame. (See Figure 4-11.)
Push in, then lift up the top section.

Figure 4-11 Mounting Plate Slot location.

2. Secure the mounting plate to the wall using the screw (#6 or #8) appropriate for the type of
wall material.

3. The mounting plate should be oriented so that the protruding tab and the three posts are
towards the bottom. Pull the wires through the hole in the rear mounting plate.

4.15 Zone Installation

4.15.1 Zone Hardware Specifications

The chart below lists all input zone hardware types available with the 4821/4820 modules.

Hardware Module Description

4821/4820 16 internal zones are built into the 4821/4820 main system board.
4825 Hardwire Zone Expander Each 4825 adds up to 64 hardwire zones. These zones have all the same

features as 4821/4820 internal zones.

4815 Serial Zone Expander Each 4815 adds up to 128 serial SmartSensor zones. The differences

between the SmartSensor zones and all other zones used in the 4821 /4820
system are described in detail in the 4815 tabbed section of this binder
(part number 150909).

4860C Touchpad Zones Two input zones are built into the 4860C touchpads. These zones have all

the same features as 4821/4820 internal zones (except that the fastest
response speed, 10 milliseconds) is not available. The installation is the
same as the 4821/4820 internal zones. See Sections 4.15.5 and 4.15.6.

Note: 4421 cannot be used wi th

the 4820 control panel.

4421 Door Access Module

Two input zones are built into the 4421. These zones have all the same
features as 4821/4820 internal zones (except that the fastest response
speed, 10 milliseconds) is not available. The installation is the same as the
4821/4820 internal zones.

4.15.2 Maximum Number of Zones per System

The maximum number of zones that can be connected to the 4821/4820 is 400.
These zones can be a combination of internal zones, 4815, 4825, 4421, and 4860C touchpad

zones.

4-20 150964

Control Panel Description an d Installation

4.15.3 Zone Configuration

At any moment an input zone can be in one (and only one) of three states, depending on the
state of the hardware circuit connected to the zone input. The possible states are Open Circuit,
EOL Circuit, and Short Circuit. The value of the EOL resistor used on all input zones in the
4821/4820 system is 4.7k ohms (Silent Knight part number 7628). 4815 SmartSensor zones
are an exception because they require a 1.43k ohm resistor (Silent Knight model 4114).

Note: UL zones must be end-of-line supervised.

Figure 4-13 Zone States

Through programming, you determine how the zone will respond to the three possible states
when it is armed and disarmed. The possible system responses for all three states are Ready,
Not Ready, Trouble, or Alarm. See Section 4.15.4 for examples of typical zone wiring.

4.16 Smoke Detector Wiring and Operation

Note: The Model 4821/4820 is not compatible with 2-wire smoke detectors.

4.16.1 Smoke Detector Compatibility

This section describes the 4821/4820 reset and smoke verification cycles. Any smoke detec­tors attached to the 4821/4820 must be compatible with the reset cycle. If you are using the
smoke verification feature, smoke detectors must also be compatible with the smoke verifica­tion cycle. See Section 4.16.1.1 for information about reset operation. See Section 6.3.2.3 for
information about programming the smoke verification option.

4.16.1.1 Smoke Reset Cycle

When you reset a smoke detector, power is off for 6 seconds. The system then applies a restart
time of 36 seconds. During the restart time, smoke power is reapplied and the zones are
allowed to stabilize. The system will not respond to fire zones during the reset period (but will
respond to other types of zones, including fire contact zones).

4.16.1.2 Smoke Verification Cycle

Smoke verification is a four-period cycle:

• Retard Period 18 second delay after a zone is tripped before smoke detector power
turns off.

• Reset Period Smoke detector power is off for 6 seconds.

• Restart Period 36 seconds for the smoke detectors to stabilize. The system will not
respond to fire zones during this time (but will respond to other
types of zones, including fire contact zones).

• Confirmation Period 60 second period during which all zones will be considered instant.
If the zone trips a second time during this period, the zone will go
into alarm immediately.

Smoke verification will not occur if any fire zones are currently in alarm anywhere in the
same partition.

Note: Smoke verification is not compatible with the 10 second zone response (debounce) speed. See Section

6.3.2.3 for more informat ion.

Section 5
System Operation

5.1 Partitions and Areas

Software partitions and areas are optional features that allow you to configure the system for a
high degree of flexibility.

The 4821/4820 can be sub-divided into multiple partitions, each of which can operate as inde­pendent systems. Each 4821/4820 system can have as many as 8 partitions, and each can
report to the central station as separate accounts. Touchpads and zones can be assigned to only
one partition.

Note: If you are installing a UL listed application, see Section 1.4.3 for UL requirements regarding partitions.

End-users and the central station may use their partition without being aware that other parti­tions exist (see). Partitioned systems do, however, share the following system resources:

T elephone lines Telephone lines and programmable options that affect general

operation of telephones.

Sirens (or bells) By default, sirens (or bells) are global features of the 4821/

4820. This means that a siren occurring in one partition would
output in all partitions. Siren/bell output can be controlled
individually through use of the optional 4880N-750-SDB Sta­tus OutputDisplay Module and programmable I/O. See the
4880N-750-SDB Installation Manual, P/N 150912TD1082
for more information.

General system operation Other operational features that affect the general operation of

the system, such as system power-up mode, are considered

system-level.
These options are described in greater detail in Section 6.3.1.1.
For controlling access within a system, partitions can be further sub-divided into as many as 8

areas. End-users may be aware that other areas exist within the partition, but they may not
have access to those areas. While partitions report as separate accounts to the central station;
areas do not. Areas, however, can share touchpads and zones.

Figure 5-1 (next page) illustrates the concept of partitions and areas.

5.9 System Test Descriptions

This section describes the walk and dialer tests and dialer reset operation in detail. See Section

5.8 for instructions about how to run the tests.

5.9.1 Walk Test

The 4821/4820 can perform two types of walk tests, 1) walk test with report and 2) walk test
without report.

• When a Walk Test without Report is executed, central station reporting is disabled. The
system reports a “T est Start” event, but no alarms or other events will be reported until the
end of the walk test.

• When a Walk Test with Report is executed, central station reporting continues to operate
normally according to the individual account set up.

During a walk test, the audio alarm shutdown is defaulted to two seconds. This allows the
installer to arm the panel and then trip each zone in turn. As each zone is tripped, the speaker
output will sound for two seconds and then shut down. This is true for all zones, including
those that have been programmed not to allow bell shutdown. All zones will be allowed to
restore two seconds after they go into alarm.

The Walk Test times out after 15 minutes. When the test is being conducted, the message

WALK TEST ACTIVE
___ sec to go

displays on the LCD. The second line indicates the number of seconds before timeout occurs.
You can end the walk test manually by selecting option 2 “End Walk Test” from the Walk
Test menu.

5.9.2 Dialer Test

When the dialer test executes, a single test report is sent to each account that has been pro­grammed as Must Report for test events.

5.9.3 Dialer Reset

When a dialer reset is conducted, all reporting is immediately aborted. All events (including
those that have not yet been reported) are cleared. The dialer remains enabled and will report
any events that occur after the reset.

System Operation

5.10 Communicating with the Computer

This section of the manual describes communication initiated by the panel. See the 5580
Upload-Download Installation and Operation Manual (P/N 150925) for information about

communication initiated by the computer.
If you are using the 4824 or phone lines to communicate, communication may be initiated

from either the panel or the computer.

• If a Requested Download or Requested Upload task is on the 5580 queue, you can process
the task from the panel. Follow the steps in Section 5.10.1.

• If more than one task for the same account is on the queue, all tasks will be processed
starting with the task at the top of the queue (the “oldest” task). The 5580 processes tasks
in the order first in, first out.

• If no task for the account is on the 5580 queue, you can send an Unsolicited Upload. Fol­low the steps in Section 5.10.1. An “Unsolicited Upload” task will appear on the 5580
queue.

• If the computer running the 5580 software has been set up to not accept unsolicited
uploads, the upload will occur, but the uploaded information is not retained. Instead, a
“Called” task will appear on the queue, notifying the 5580 operator that the panel
attempted to upload.
