SYSTEM OVERVIEW

INTRODUCTION TO NETWORKING

The Simplex 4120 Network is a system of individual Fire Alarm Control Panels communicating on a loop as a peer-

to-peer network. This means that every network panel has an equal chance of putting a message out on the network.

Each panel with direct communications into the 4120 Network is defined as a “ Node” . Each node can maintain the

status and control of its own dedicated circuit points while monitoring and controlling activity at other locations.

The communications scheme used by the network is based on Token Ring Communications Protocol. In Token Ring
communications, an electronic data “ flag” or “ token” is passed from one node to the next. The node that holds the
token is the only one permitted to talk on the network. A node that has no messages or requests for the network

simply passes the token onto the next node. Thus, every node has an equal chance of putting a message out on

the network when needed.

A 4120 Network Node can be any of the following:

l

4120-8001 Fire Alarm Control Panel

l

4120-8201 Voice Fire Alarm Control Panel

l

4120-8010 Miniplex Control Panel

l

4120-8210 Voice Miniplex Control Panel

l

4120-8511 Universal Transponder (UT)

l

4120-8601 Voice UT

l

4120-8602 UT Status Command Center (Voice Modules optional)

l

4120-8801 2500-Point Network Display Unit (2500 NDU)

l

4120-8821 2500 NDU with Command Center.

The following two additional 4120-series panels are available as “ sub-panels” to the system nodes:

l

4120-8019 Miniplex Transponder (for Miniplex Nodes only)

l

4120-8009 Remote Annunciator Panel.

An existing 4100 Fire Alarm Control Panel or Universal Transponder can also be included in the network by installing

the after-market 4120-0140 RS-485 Network Interface Card into a panel slot in the existing unit and configuring the

panel to accept the card.

41 OO-family panels compatible with the 4120-0140 Network Interface Card are:

l

4100-8001 Fire Alarm Control Panel

l

4100-8201 Voice Fire Alarm Control Panel .

l

4100-8010 Miniplex Control Panel

l

4100-8210 Voice Miniplex Control Panel

l

4100-8511 Universal Transponder

l

4100-8601 Voice Universal Transponder

l

4100-8602 UT Voice Status Command Center.

Network information is sequentially transmitted from one node to another. At each node, the network message is

captured and either retransmitted as received, or modified before retransmission to provide the network with a status

update. The ability of the message to circulate through the network defines network status and allows the nodes to

respond accordingly.

If a node goes off-line, its network interface module will bypass that connection until the node is back on-line. If the
wires between nodes short, open, or have any other form of communication problem, the network will isollate that
section of wiring. A node that cannot retransmit a message to the next node will transmit back to the previous node
to maintain communications and to notify the network of the node status.

In the event of multiple wiring problems, the remaining nodes will effectively “ regroup” and establish new, smaller

“ sub-networks” that will maintain communications among the active nodes.

SYSTEM INTRODUCTION

2500 NETWORK DISPLAY UNIT (4120-8801)

The Simplex 2500 Network Display Unit (NDU) is a network annunciator and manual system/point controller for a
4120 Network. The NDU provides alphanumeric annunciation for up to 2,500 network points and/or point lists and
can be programmed to function as the network master controller for Silence, Acknowledge, and System Reset.

Standard features include an alphanumeric display exactly like the 4100 Fire Alarm Control Panel, a SPDT Trouble
Relay, City Connect Circuitry, and more memory to achieve 2,500 point capacity.

The increased memory size provides 600 alarm and 600 trouble event history logs, twice the size of any other 4120
or 4100 model. The 2500 NDU can drive up to 31 serial LCD Annunciators on one optional Remote Unit Interface
(RUI) card. In addition, the NDU can have up to five RS-232 ports for printers and CRT/Keyboards.

2500 NDU WITH STATUS COMMAND CENTER (4120-8821)

The 2500 NDU with Status Command Center combines the 2500 NDU with a custom selection of modular I-IED and/
or LED and control switch assemblies that provide a dedicated monitor and control interface. Voice modules are
available with this model to configure this panel into a Voice Command Center.

The NDU with Status Command Center is actually two nodes in one cabinet assembly. The NDU occupies the top
bay of the unit and the Command Center occupies the rest.

Unlike 4100 panels where there are two Product I.D. types, one for Voice and Non-Voice packages, the 4’ 120-8821
NDU can be either configuration. As with the standard 2500 NDU package, both models can be COnfigured for
redundant or remote command center applications.

SYSTEM OPERATING DESCRIPTION

NOTE:

An alphanumeric display on the 2500 NDU Operator Interface Panel (Figure 1) indicates the condition of the system.
The alphanumeric display shows the various labels
operation for each abnormal condition.

This document covers the operating procedures for a typical 2500 NDU. Applications will vary due to
custom programming and local code requirements.

Audible and visual indication are provided to indicate abnormal conditions, when they exist throughout the network.

The 2500 NDU Operator Interface Panel, hereinafter called the interface panel, shows the following under normal
conditions:

l

Green “ POWER ON” LED ON (indicating that AC power is applied)

l

All other interface panel indications OFF

l

Alphanumeric display states that the system is normal, as shown below.

SYSTEM IS NORMAL

I

Abnormal conditions are indicated on the interface panel by flashing the alarm, supervisory, or trouble LED and
sounding the tone-alert. The alphanumeric display provides information as to the point status (alarm, supervisory,
and trouble), type of alarm (smoke detector, pull station etc.), number of abnormal conditions in the system, and a
custom label. Alarm, supervisory, and trouble conditions each have their respective acknowledge key. Pressing the
appropriate acknowledge key will silence the tone-alert. However, the LED indicating the abnormal condition

remains illuminated until all initiating devices are restored to normal.

If your system is configured with the CRT or printer option, point status is also displayed on these devices. The CRT
option controls various system functions. It can acknowledge system status changes, silence alarm signals, and
perform system reset procedures.

When an initiating device (monitor point) senses an Alarm Condition (heat, smoke, manual activation, etc.),

notification appliances (signals) and the tone-alert sounds, and the SYSTEM ALARM LED turns ON and flashes,
indicating that an alarm condition is present. In addition, depending on the nature of the alarm condition, relays trip,
the city circuit is activated, and various programmed events occur.

When an initiating device senses a Supervisory Service Condition (tamper valve off normal, generator status, etc.),
programmed notification appliances and the tone-alert sounds, the SUPERVISORY SERVICE LED on the interface
panel turns ON and flashes, the city circuit may be activated (if required by local codes), and various programmed
events occur.

3

When the NDU senses a malfunction within the system (loss of power, hardware failure, etc.), a Trouble Condition
is announced by the interface panel. The tone-alert turns ON and remains steady ON, the SYSTEM TROUBLE LED
flashes and various programmed events occur.

NOTE:

All abnormal conditions must be acknowledged by pressing the Acknowledge Key under the appropriae flashing
LED. Notification appliances are then silenced by pressing the <ALARM SILENCE> key. Depressing the <:SYSTEM
RESET> key restores the system to the normal operating mode (if conditions have been acknowledged and
restored).

The tone-alert may be programmed to sound at specified time intervals to serve as a reminder that a trouble still
exists within the system (System Trouble Reminder).

The system has ‘ Ire-sound” capability. If, after silencing the signals, the system detects another abnormal condition,
the zone with the abnormal condition is indicated on the interface panel alphanumeric display, the appropriate
indicator again flashes, and the signals again sound.

To provide maximum efficiency in performing primary fire alarm functions, an interface panel access door, shown in
Figure 1, covers all keys except those required for indication and interaction for emergency situations.

When an Operator Interface Panel Key is referenced within this manual, it is normally shown between left
and right arrows. Examples are <ALARM ACK> and <ALARM SILENCE>.

HANDLING ABNORMAL CONDITIONS

When an abnormal condition occurs, at least one of the interface panel LEDs (SYSTEM ALARM, SUPERVISORY
SERVICE, or SYSTEM TROUBLE) begins to flash, and the tone-alert sounds. The alphanumeric display on the
interface panel shows the total number of abnormal conditions present in the system. At a glance, you know how
serious the situation is by reading the number of abnormal conditions displayed, such as the single alarm condition
shown below.

***ALARM***

ALARMS = 1 SUPERVISORY = 0

I

The NDU also creates a “ List” when abnormal conditions exist. The list contains the number of abnormal conditions
present in the system. The acknowledge keys are pushed to view the abnormal condition list, and review each
condition, if required.

When an Alarm Condition is detected by the NDU, the SYSTEM ALARM LED flashes and the tone-alert begins
pulsing. For supervisory service and trouble conditions, the appropriate interface panel LED flashes, and he tone­alert sounds and remains ON without pulsing.

Press <ACK> to review.

I

Pressing the appropriate cACK> key (under the flashing LED) displays the first acknowledged condition in the
appropriate list. Note that the acknowledge function may be passcode protected. If you have insufficient privilege to
acknowledge the condition, a message will indicate the problem, and will allow you to view the points without
acknowledging them. If you have sufficient privilege to ackncwledge the condition, a message is displayed informing
you that the condition has been acknowledged. (See Operator Access Levels, Section 9, and Log In Procedure for
details.)

The NDU can be configured with either Global or Individual Acknowledge. When Global Acknowledge is used, one
press of an cACK> key
are acknowledged in this manner, an appropriate message is displayed. When Global Acknowledge is used, and
the supervisory service or trouble conditions clears, the abnormal condition will automatically clear. If Individual
Acknowledge is used, the appropriate cACK> key must be pressed for

The <DISPLAY TIME> Key

The <DISPLAY TIME> key is used to view the time of day when the abnormal condition occurred. By viewing the
time for each abnormal condition occurrence, fire department personnel can determine the path and possible cause
for each abnormal condition.

Note that the <DISPLAY TIME> key only displays time for existing abnormal conditions.

Using the <DISPLAY TIME> Key

The red <DISPLAY TIME> key works for any point currently in an alarm, supervisory, or trouble condition. The time/
date information is obtained from the historical log and is shown on the alphanumeric display. In situations where

multiple conditions are present, you can simply push one key to review the time that each abnormal condition

occurred. An example of an alarm condition is shown below.

ESSENTIAL ALARM CONDITION KEYS

The essential keys for alarm conditions are the <ALARM ACK> (Alarm Acknowledge), <ALARM SILENCE>, and
the <SYSTEM RESET> keys. The remaining keys are concealed by the interface panel access door and are
associated with advanced system functions. (See Section 9, Advanced Functions.)

ALARM ACKNOWLEDGE KEY

The <ALARM ACK> key is located directly under the SYSTEM ALARM LED. Pressing the <ALARM ACK> key
(m for Individual Acknowledge or once for Global Acknowledge) causes the SYSTEM ALARM LED to change
from flashing to steady ON and silences the tone-alert. Pressing the <ALARM ACK> key does the following:

l

Selects the next unacknowledged alarm point in the list for display (Individual Acknowledge)

l

Acknowledges the displayed point or acknowledges all points on the list (Global Acknowledge)

l

Scrolls the points chronologically after all points have been acknowledged.

11

If the <ALARM ACK> key is passcode protected, you cannot use this key to acknowledge alarms unless you have

the required access level. See Operator Access Levels (Section 9) and Log In Procedure (Section 1).

There are two types of acknowledges for the NDU: Global Acknowledge and Individual Acknowledge. Each
acknowledge type operates with the System Alarm Condition in the following manner.

l Global Acknowledge -

When Global Acknowledge is used, a single key press of the <ALARM ACK> key

acknowledges all alarm status changes in the system. If status change information is required, you may review
this data (after a 60 second delay) by pressing the <ALARM ACK> key and reading the total numbl2r of alarm
status changes on the alphanumeric display.

l Individual Acknowledge

(For NFPA 72-1990 Requirements) - If an alarm condition n’ as been
acknowledged with the <ALARM ACK> key and further unacknowledged conditions remain in the system, the
tone-alert continues to sound and the next status change is shown on the alphanumeric display. This process
repeats until all changes are acknowledged. When this occurs, the tone-alert is silenced, and the highest
priority acknowledge change is indicated pn the display.

ALARM SILENCE KEY

CAUTION

THE ALARM SILENCE KEY PRESS WILL CAUSE FIRE ALARM EVACUATION SIGNALS TO TURN

---

QFJ. FOLLOW LOCAL PROCEDURES TO SILENCE ALARM EVACUATION SIGNALS.

When an alarm condition exists, various signals,, auxiliary relays, the city connection, and the tone-a.lert may

activate, depending on the system configuration and the stage of the alarm condition. The <ALARM SILEFJCE> key,
when pressed, turns OFF all circuits programmed to follow the Alarm Silence key. The <ALARM SILENCE> key
press will:

SYSTEM RESET KEY

The <SYSTEM RESET> key is used to return the system to its normal state after an alarm condition has been
cleared. When the <SYSTEM RESET> key is pushed, it causes any latched circuits to reset automatically. Also

reset are initiating devices, relays (including the city relay), notification appliances, and all LEDs and indicators which

are programmed to reset with the <SYSTEM RESET> key. The message, ‘ SYSTEM RESET IN PROGRESS” , is
displayed when the <SYSTEM RESET> key is pressed. With Individual Acknowledge systems, when the alarm
condition has reset, the SYSTEM ALARM LED flashes, and the system requires that the <ALARM ACK> key be

pressed.

If a zone stays in alarm during the reset period, the message, “ SYSTEM RESET IN PROGRESS” , is followed by the

message shown below.

ALARM PRESENT, SYSTEM RESET ABORTED

I

When the “ SYSTEM RESET ABORTED” message is displayed, the system remains in an alarm state. The display
indicates the total number of alarms present in the system along with a prompt to use the <ALARM ACK> key to
review the points. These points do not require acknowledgment. The SYSTEM ALARM LED remains ON to indicate
that a fire alarm device is still in an alarm condition.

If the system does not reset, and the display still shows an alarm although no fire exists, read the alphanumeric

display on the interface panel to determine the type of device and the zone number in alarm. Follow local procedures
to investigate the area of the building with the alarm. Look for devices still in alarm (pull stations, smoke detectors,
etc.). Most devices latch until they are reset, either by the system or manually.

I

IF THE ALARM POINT DOES NOT RESET

If a device does not reset, you may choose to perform the Disable Procedure given in the following paragraphs.

HOW TO DISABLE A POINT

CAUTION

DISABLING A POINT CAUSES THAT POINT TO NOT REPORT ALARM CONDITIONS OR OTHER
STATUS CHANGES. A POINT SHOULD NOT BE DISABLED UNLESS IT IS CLEARLY UNDERSTOOD
THAT FIRE DETECTION FOR THE AREA OF THE BUILDING COVERED BY THAT POINT WILL BE
LOST. APPROPRIATE STEPS MUST BE TAKEN TO PROVIDE ALTERNATE MEANS OF FIRE
PROTECTION FOR THAT AREA OF THE BUILDING WHILE THE POINT IS DISABLED.

If a device does not reset, you may disconnect the device/point causing the alarm condition. However, this point
must first be identified. Press the <ALARM ACK> key, and read the alphanumeric display on the interface panel.
Then, disable the identified alarm point with the <DISABLE> key. If the <DISABLE> key is passcode protected,
perform the Log In Procedure before performing the Disable Procedure.

The <DISABLE> key press may remove power to a displayed monitor point. Thus, disabling a point causes a trouble
condition on the individual zone.

ESSENTIAL TROUBLE CONDITION KEYS

The essential keys for trouble conditions are the Trouble Acknowledge cTBL ACK> and the <SYSTEM RESET>

keys. The remaining keys are concealed by the access door and are associated with advanced functions of the
system (see Section 9, Advanced Functions). Use of these keys require advanced user skills. These keys may be
passcode protected. See Operator Access Levels (Section 9) and Log In Procedure (Section 1).

TROUBLE ACKNOWLEDGE KEY

The cTBL ACK> key is used to scroll through the various displays on the alphanumeric display. It also controls the
Trouble LEDs and the tone-alert. The cTBL ACK> key is located directly under the SYSTEM TROUBLE LED.

Pressing the cTBL ACK> key (twice for Individual Acknowledge or once for Global acknowledge) causes the LED
to change from flashing ON to steady ON, silences the tone-alert, and causes the following to occur:

l

Selects the next unacknowledged trouble point and displays it on the alphanumeric display (Individual

Acknowledge)

l

Acknowledges the displayed point or acknowledges all points on the list (Global Acknowledge)

l

Silences signals programmed to follow the Trouble Acknowledge key

l

Scrolls the points chronologically after all have been acknowledged.

If the cTBL ACK> key is passcode protected, you cannot use this key to acknowledge troubles unless you have the
required access level. See Operator Access Levels (Section 9) and Log In Procedure (Section 1).

There are two types of acknowledges for the NDU: Global Acknowledge and Individual Acknowledge. Each
acknowledge type operates with the System Trouble Condition in the following manner.

l Global Acknowledge -

When Global Acknowledge is used, a single key press of the cTBL ACK> key

acknowledges all troubles in the system. If status change information is required, you may review this data

(after a 60 second delay) by pressing the cTBL ACK> key and reading the total number of, troubles on the

alphanumeric display.

l Individual Acknowledge

(For NFPA 72-l 990 Requirements) -

If a trouble condition has been
acknowledged with the cTBL ACK> key and further unacknowledged conditions remain in the system, the
tone-alert continues to sound and the next status change is shown on the alphanumeric display. This process
repeats until all changes are acknowledged. When this occurs, the tone-alert is silenced.

17

SYSTEM RESET KEY

NOTE:

Normally, trouble points do not require acknowledgment of the cleared condition. If the system does not clear, read
the display, then, check for devices still in trouble (pull stations, smoke detectors etc.). Call Simplex to repair the
system.

Some troubles latch until they are reset manually or are reset by pressing the <SYSTEM RESET> key. These
troubles include Style D (formerly Class A) initiating device circuit troubles, reverse polarity city circtiil trouble
conditions, and shorts on 24-Point I/O cards.

If a monitor point intermittently toggles into trouble, or will not reset, you may choose to disable that point, using the
procedure given in the following paragraphs.

The <SYSTEM RESET> key is also described in Section 2 of this document.

IF THE TROUBLE DOES NOT RESET

If a trouble condition does not clear after a device has been restored, press the <SYSTEM RESET> key. If the
condition does not clear, or continually toggles troub!es, the trouble has not been corrected. Read the alphanumeric
display on the interface panel to determine the location and type of device/point with the trouble condition. You may
choose to either disconnect the device, or to disable the trouble point by performing the Disable Procedure given in
the following paragraphs.

HOW TO DISABLE A POINT WITH A TROUBLE CONDITION

CAUTION

DISABLING A POINT CAUSES THAT POINT TO NOT REPORT ALARM CONDITIONS OR OTHiER
STATUS CHANGES. A POINT SHOULD NOT BE DISABLED UNLESS IT IS CLEARLY UNDERSTOOD
THAT FIRE DETECTION FOR THE AREA OF THE BUILDING COVERED BY THAT POINT WILL BE

LOST. APPROPRIATE STEPS MUST BE TAKEN TO PROVIDE ALTERNATE MEANS OF FIRE
PROTECTION FOR THAT AREA OF THE BUILDING WHILE THE POINT IS DISABLED.

If a point does not reset, you may disable the point causing the trouble condition. However, this point must first be
identified. Press the cTBL ACK> key, and read the alphanumeric display on the interface panel. Then, disable the
trouble point with the <DISABLE> key. If the <DISABLE> key is passcode protected, perform the Log In Procedure,
before performing the Disable Procedure.

Note that the <DISABLE> key press removes power to any displayed monitor point. Thus, disabling a point causes
a trouble condition on the individual zone.

To disable a point, perform the following procedure.

1. Open the interface panel access door.

(See Section 10, How To Enable

INTRODUCTION

The devices that are used for the TrueAlarmTM operation are considered sensors instead of detectors, because

these devices do not determine alarm conditions. The TrueAlarmTM
data regarding smoke density to the NDU control panel. The TrueAlarm
but sends temperature data instead of smoke density data. The NDU uses this data to determine whether a trouble
has occurred. This basic operational difference is the key to TrueAlarmTM operation.

The TrueAlarmTM sensor has two automatic trouble indications:

l

Dirty, and

l

Excessively Dirty.

A sensor “ dirty” trouble condition is reported any time the average value on an individual sensor reaches a set
threshold value.

A sensor “ excessively dirty” trouble condition is reported anytime the average value of an individual sensor reaches
a slightly higher threshold level. Although an “ excessively dirty” trouble is reported, the sensor will continue to
operate and will report an alarm condition if one is detected.

In addition to the two automatic trouble conditions, the 4120 software includes a preprogrammed digital pseudo point
(P132, Sensor Almost Dirty Log Enable) that can be turned ON at the NDU front panel and the owner node to allow

a TrueAlarmTM sensor that is close to being a “ dirty” sensor to report as if it were one. This is useful when

maintenance is being scheduled for dirty sensors, as it provides a means of seeing if other sensors are approaching

a “ dirty” state.

smoke sensor is a measuring device that sends

TM heat sensor operates in a similar fashion,

19

Once a minute, the 4120 software performs a self-alarm test of each TrueAlarm
the value of each sensor to a value that simulates an alarm condition. If the sensor reports back a value that is not
within the alarm range, a “ self-test abnormal” trouble will be displayed for that specific sensor.

The following paragraphs discuss the responsibilities of operators when these trouble indications occur.

TM sensor. The self-alarm test raises

ALMOST DlRTY

Using the front panel keypads, it is possible for a SIMPLEX Field Service representative to turn on a system point
that allows an “ almost dirty” sensor to report a trouble. Although the “ almost dirty” sensor is holding its sensitivity
level, the operator can schedule maintenance for the sensor before the dirty sensor trouble occurs.

DIRTY

A “ Dirty” indication means that the sensor is holding its sensitivity level, but that the operator should schedule
maintenance for the sensor. Clean the sensor as required, and, if necessary, call Simplex for service.

EXCESSWEL

The “ Excessively Dirty” indication means that the sensor may no longer be compensating for dirt and dust. t3ecause
false alarms are possible with this condition, sensors must be cleaned as soon as possible. If necess.ary, call
Simplex for service.

SELF-TESTABNORMAL

All system sensors are automatically tested once every minute. If a sensor fails to report properly to the NDU, a “ self­test abnormal” condition occurs. Since the sensor is not working properly, it must be replaced. Replace it, or call
Simplex for service.

SUPERVISORY SERVICE CONDITIONS

INTRODUCTION

A Supervisory Service Condition is used to indicate the operative condition of Automatic Sprinkler Systems and
other systems used for the protection of Life and Property. A Supervisory Service indication may indicate that one

of these systems is inoperative.

NOTE:

When a System Supervisory Service Condition is detected by the NDU, the condition is indicated by the following:

The panel has one yellow SUPERVISORY SERVICE LED which lights when a supervisory service condition is

present in the system. When such a condition occurs, the LED flashes, the tone-alert is ON steady, and a
supervisory service message is displayed by the alphanumeric display on the interface panel. When the &UPV
ACKz key is pressed, the SUPERVISORY SERVICE LED flash becomes a steady glow, and the tone-alert is
silenced.

Refer to Figure 4 for locations of Operator Interface Panel LEDs and Keys.

ESSENTIAL SUPERVISORY SERVICE CONDITION KEYS

The essential keys for supervisory service conditions are cSUPV ACK> and the <SYSTEM RESET> keys. The

remaining keys are concealed by the access door and are associated with advanced functions of the system. (See

Section 9, Advanced Functions.)

SUPERVISORY ACKNOWLEDGE KEY

The &UPV ACKz key is used to scroll through the various data fields on the alphanumeric display. It also controls
the SUPERVISORY SERVICE LED and the tone-alert. The &UPV ACK> key is located directly under the
SUPERVISORY SERVICE LED. Pressing the &UPV ACK> key (w for Individual Acknowledge or once for
Global Acknowledge) causes the LED to change from flashing ON to steady ON, and silences the tone-alert. The
cSUPV ACK> key press does the following:

l

Selects the next unacknowledged supervisory point and shows it on the display (Individual Acknowledge)

l

Acknowledges the displayed point or acknowledges all points on the list (Global Acknowledge)

l

Scrolls the points chronologically after all points have been acknowledged.

NOTE:

There are two types of acknowledges for the NDU: Global Acknowledge and Individual Acknowledge. Each
acknowledge type operates with the Supervisory Service Condition in the following manner.

The eSUPV ACK> key may be passcode protected. If you do not have the required access level, you will
not be able to acknowledge supervisory conditions. See Operator Access Levels (Section 9) and the Log
In Procedure (Section 1) for details.

23

l Global Acknowledge -

When Global Acknowledge is used, a single key press of the <SUPV ACK> key

acknowledges all supervisory service changes in the system. If status change information is required, you may

review this data (after a 60 second delay) by pressing the &UPV ACK> key and reading the total number of

supervisory service changes on the alphanumeric display.

l Individual Acknowledge

(For NFPA 72-l 990 Requirements) - If a supervisory service condition has been

acknowledged with the cSUPV ACK> key and further unacknowledged conditions remain in the system, the

tone-alert continues to sound and the next status change is shown on the alphanumeric display. This process

repeats until all changes are acknowledged. When this occurs, the tone-alert is silenced and the highest

priority acknowledge change is indicated on the display.

.

SECTION 5

RS-232 INTERFACE

INTRODUCTION

Up to five RS-232 ports are available in the NDU. The RS-232 interface option supports both printers and video
terminals to annunciate alarm, supervisory, and trouble conditions.

M-232 PORT ACCESS LEVELS

The NDU interface panel, and each RS-232 Interface Port configured for a video terminal, are programmed to allow
certain operations at each access level. You must be “ logged in” at the required access level or higher to perform
the various system operations. Up to 20 operators are allowed to log in at the various passcode access levels. The
number of operators, passcode access levels, and the allowed operations are programmed into the system
dependant on the customer requirements.

If a port is not configured to annunciate a class of events, such as supervisory conditions, you will not be able to
acknowledge those points with the video terminal keyboard, even though the video terminal is connected to that port,
regardless of the passcode level entered. Table 1 lists the default protection levels for the RS-232 interface. These
levels are programmed to meet customer requirements.

SET-UP PROCEDURE

The CRT must be set-up correctly in order to receive and transmit data. An operator may enter the set-up mode to
verify proper configuration. However, set-up procedures are performed by Simplex personnel and should not
normally be performed by operators. (See publication FA4-1 l-224 for CRT set-up parameters.)

CRT SCREEN DISPLAYS

A variety of CRT screen displays are used to support system operations. Header information is displayed on the first
three lines of the screen. The first line shows the time on the left, custom banner in the center, and the operator on
the right side of the screen. The second line shows the date on the left and the current access level on the right. The
third line shows the overall system status. Prompt/Message information is shown on all screens. The bottom line
displays prompts, help messages, and error messages. These screens tell you what to do and when to dcl it. CRT
screen displays are shown in Figures 5 through 9.

CRT MAIN MENU SCREEN

The CRT Main Menu Screen (Figure 5) is the first screen to appear after power is applied to the system. From the
Main Menu Screen, you can display various system information screens, Items 1 through 6 are the available choices
within this menu. View any item by either moving the cursor to the selection or by typing the item number and then
pressing the <Enter> key.

ACKNOWLEDGE SCREEN

The entire system is configured as either a Global Acknowledge system or as an Individual Acknowledge system.
If the system is configured as a Global Acknowledge system, two presses of the <PFi> key will acknowledge all
abnormal conditions ‘ that can be annunciated by the port. When the system is configured as an Individual
Acknowledge system, the Acknowledge key, cPFl>, must be pressed to acknowledge each condition change.

All conditions which can be displayed at the CRT can be acknowledged at the CRT, provided that you have logged
in at a sufficient access level. A tone on the CRT sounds to indicate unacknowledged conditions. (The tone can be
silenced with the cPFl> key.) When an abnormal condition occurs, you must select the appropriate acknowledge
screen. The Header information on the screen indicates the number of abnormal conditions which can be
annunciated by the CRT, and not necessarily the total number of abnormal conditions in the system. To acknowledge

an abnormal condition, press the <PFi> key while in the acknowledge screen. The displayed condition will stop
flashing, but will still indicate the abnormal condition. When all abnormal conditions have been acknowledged, you
can return to the Main Menu by pressing the cF18> key.

As with the operator interface, alarms have priority over supervisory and trouble conditions. Multiple conditions are
displayed in chronological order. Should multiple unacknowledged conditions occur, no unacknowledged event is
allowed to scroll off the screen. If more unacknowledged conditions exist in the system than can fit on the screen,
the “ oldest” unacknowledged point is displayed first. After that condition is acknowledged, it scrolls off the top of the
screen and is replaced by the next oldest condition.

27

The acknowledge screens are dynamic, and information is updated once per second. Follow the proml)ts at the
bottom of the screen (shown in Figure 2) to silence signals (<PF2> key), or to reset the system (cPF3> key). When
the system has reset, press the cPFl> key to acknowledge the condition change.

NDU AUDIO SYSTEMS

GENERAL INFORMATION

The following paragraphs describe the features and general operating procedures of the 2500 NDU with Status
Command Center, Voice option.

INTRODUCTlCiN

This section covers the following topics:

l

General Audio System information

l

Single Channel Audio operation

l

Dual Channel Audio operation

l

Triple Channel Audio operation

l

Phone operation

l

Optional Feature operation.

Contact your local Simplex branch office to determine your audio configuration. Use the topics that apply
to your audio system.

AUDIO FEATURES

The NDU Voice Communications option provides automatic alert and evacuation messages over pre-programmed
speaker circuits during an alarm condition. Evacuation messages may also be manually initiated either to all areas
of a building or to specific areas within the building. The dedicated system microphone provides live voice message
delivery to any area within the building. Voice messages or voice codes can be created with the English language
(or a foreign language). Two-way communications are available with the Fire Fighter’ s Phone System. The NDU’ s
phone-to-audio interface enables the Master Phone or any remote Fire Fighter’ s phone to be patched through the
audio system and operated as a microphone.

SYSTEM OPERATION

The NDU audio system is configured and programmed to meet individual customer and code requirements. Audio
systems are available as Single Channel, Dual Channel, and Triple Channel configurations. Single Channel systems
can output one tone or message at a time. Dual Channel systems can output two tones or messages simultaneously.
Triple Channel systems can output two tones or messages AND a talk output simultaneously. Signal routing and the
purpose of each channel depends on the number of audio channels in the NDU, as shown in Table 3.

Table 3

CHANNEL 1 = EVAC
CHANNEL 2 = ALERT

CHANNEL 2 = TALK

TRIPLE CHANNEL

CHANNEL 1 = EVAC
CHANNEL 2 = ALERT
CHANNEL 3 = TALK

33

AUDIO CONTROL LED/SWITCH MODULE

Control of audio functions are performed by operating switches on LED/Switch modules which are mounted on the
NDU Front Panel. The functions and quantity of the LED/Switch modules depend on the desired options and the
number of channels in the audio system. Labels are inserted into the slots on the LED/Switch modules to identify

the function of each switch and LED.

Standard switches on the Audio Control LED/Switch Module for Single and Triple Channel operations are three

position, momentary switches. Dual Channel systems normally use three-position maintained switches. An optional
Audio Control LED/Switch Module with three-position momentary switches is available for Dual Channel audio
systems.

VOICE MESSAGES

The NDU audio system is available with Voice Messages. These messages are selected at order entry to meet
customer requirements. The messages may contain various tones along with specified phrases which instruct
building occupants to behave in a manner appropriate to the abnormal conditions. An example of the Drill Message
follows:

“ This is a drill. This is a drill. This is a drill. All occupants report to the nearest stairway exit

dloor,

and await further orders. Do not enter stairway.”

NOTE:

The above Drill Message will play three times. It may be followed by another Voice Message, or the operator

may elect to use the audio system microphone for additional announcements.

VOICE CODED DIGITS

Voice Coded Digits (0 through 14) are also available to support audio messages. These are spoken numbers which
identify a location or condition within the building. They are normally used in conjunction with Preambles.

PREAMBLES

Preambles for Voice Coded Messages are available with the NDU. These Preambles are specified at order entry

and are programmed into the system to meet customer requirements. An example of a Preamble with Voice Coded
digits is:

“ Dr. Red, your assistance is required in area Three - One - Four.“

Other examples of Preambles are as follows:

l

“ A Fire Emergency has been reported in area (voice coded digits).”

l

“ Dr. Firestone, please dial (voice coded digits).”

l

“ An emergency has been reported in area (voice coded digits).”

l

“ Dr. Blaze, please dial (voice coded digits).

34

TROUBLE MESSAGES

Trouble messages from the system are shown on the alphanumeric display and entered into the Trouble Log. The
operator uses the operator interface panel keys to acknowledge the trouble, silence the alarm, and reset the trouble
condition. See Section 3, Trouble Conditions, for required operations.

Walk TestTM

A Walk TestTM must be conducted at each panel individually. Zones going into Walk TestTM alarm will not be visible
to or annunciated at other network panels. However, signals at other panels may be affected if external signal points

are included in Walk TestTM output lists.

SECTION 8

MAPNET II@

INTRODUCTION

The MAPNET II@ option allows the use of addressable devices and TrueAlarmTM sensors with the system.
Addressable devices communicate the exact location of an alarm to the NDU operator interface panel, improving

recognition of the condition and the subsequent response. It also pinpoints the precise location of trouble conditions

via the custom label description.

A TrueAlarmTM sensor measures smoke density or heat intensity, but has no self-contained alarm set point. The
alarm set point is programmed into the network node. Thus, the decision is made by the network node, rather than
by the sensor.

MAPNET II@ ALPHANUMERIC DISPLAYS

When a MAPNET II@ device changes to an abnormal state, or the operator enters a MAPNET II@ device address,
the NDU alphanumeric display shows the current status of the MAPNET II@ device. After entering a MAPNET II@
device address, press the <FUNCTION> key on the operator interface panel to display additional device information.

For the TrueAlarmTM sensor, device information reported back to the NDU operator interface panel also includes
data about the condition of the sensor itself. For example, the sensor might report that it is dirty or excessively dirty.

MAPNET II@ POINT ADDRESSING

Each MAPNET II@ device must have a point address in order to communicate with the NDU. These point addresses,
along with their custom labels, are located in the Programmer’ s Report. The Programmer’ s Report shows the

must

address for each device, separated by hy hens. Hyphens
the system. An example of a MAPNET II
owning node. The “ Ml” portion of the address identifies the MAPNET II@ channel, channel 1. The “ 5” portion of the
address identifies the device number, number 5. MAPNET II@ channel numbers range from 1 through 9, and 0, with

MAPNET II@ channel 0 actually being channel 10.

8 .

device address is “ 3:Ml-5” . The “ 3:” portion of the address identifies the

HOW TO DISPLAY A MAPNET ll@ SYSTEM POINT

See Section 9, “ How to Display MAPNET II@ Point Status” , for MAPNET II@ operations. This procedure also shows

how to use the Programmer’ s Report to find MAPNET II@ addresses.

WHAT TO DO IF A MAPNET II@ POINT WILL NOT RESET

If a MAPNET II@ device will not reset, you may decide to disable the point with the <DISABLE> key. When the
disable procedure is performed, a System Trouble occurs to remind you that the point is disabled. The disable
procedure is the same for all system points. (See Section 2, “ How to Disable a Point” .) Maintenance personnel must
be called immediately to repair the malfunction.

After the MAPNET II@ point is repaired, you can enable the point again. (See Section 10, “ How to Enable a Disabled

Point” .) This procedure is the same for all system points.

ADVANCED FUNCTIONS

INTRODUCTION

When more involved operator functionality/control is required, simply open the NDU Operator Interface Panel
“ Access Door” to expose the additional keys which are available for advanced functions. Figure 32 shows the
operator interface panel with the access door open and the advanced function keys displayed.

Figure 32

Operator Interface Panel Controls and Indicators

Control Keys

Five CONTROL keys and their associated LEDs (Figure 33) are located on the far left of the operator interface panel.

Normally, these keys and LEDs are concealed by the access door. A custom label is used to identify the desired
function. Typical functions for these keys are city disconnect, manual evacuation, door holder bypass, start a drill,
control all signals, elevator capture, control air handling units, and manual control. When a control key is pressed,
the programmed event occurs.

CAUTION

OPERATION OF THESE KEYS MAY CAUSE ALARM SIGNALS TO SOUND OR TROUBLE

CONDITIONS TO BE GENERATED BY THE SYSTEM.

These keys can be pressed anytime, and the key feedback (beep) may be the only acknowledgment of the action.
Typically, the LED tracks the function and illuminates each time the associated key is pressed.

Use of key functions can be controlled by assigning operator access levels to each key (See Section 9, Operator

Access Levels, and Section 1, Log In Procedure).

FUNCTION KEYS

Four FUNCTION KEYS (cFi>, <F2>, <F3>, and cF4>) are located directly above the alphanumeric display (See

Figure 34). Within the Main Menu options, these key definitions change as required to perform specific actions for
selected Main Menu options. The definitions for each key are shown on the top line of the alphanumeric: display as
an aid to the user. A function key does not require any other key to be pressed to activate its function. Pressing a
key causes that key to immediately perform its defined task. Pressing a key which has no defined action for the
current function has no effect. However, the tone-alert acknowledges the key press with a “ beep” . These four keys
are associated with advanced functions of the system within the Main Menu options, and within point displays.
These keys may be passcode protected for some of the defined operations.

The cFl>, cF2>, cF3>, and cF4> keys have extended actions defined during point displays when used in
conjunction with the <FUNCTION> key on the DISPLAY/ACTION keypad. The actions vary with the point and status
displayed.

POINT SELECTION

Selecting Points Using Lists

Many of the functions performed from the operator interface panel display point specific data. Every system point is
part of the “ Select A List of Points” list in the main menu. All points can be displayed sequentially by address order
using this list option. To facilitate the search for a particular point, lists may be selected by type groupings (monitors,
signals, auxiliary, input/output, pseudo points etc.). A list of points may be selected, then scrolled through by using

the <NEXT> and <PREVIOUS> keys. Selecting a list of points will expedite the search for a specific point with a

minimum of scrolling.

Selecting Points Using the Keypad

Rather than scrolling through a list, you may use the keypad to select a point. If the input represents a valid point in
the system, that point will be shown on the alphanumeric display. After a point has been displayed, you can scroll
through all the points in the system from that point, or select another point directly by entering another identifier using
the keypad.

You have the choice of entering a point number or an address number. The format for entering a poirt identifier
address requires a hyphen. Only numbers and the hyphen keys are valid entries. The maximum number of digits
allowed in an identifier input is eleven (ll), including the hyphens, excluding the <ENTER> key.

Selecting Additional Lists

When an abnormal condition occurs, a record of the event is placed in one of two logs generated by the system,
depending on the nature of the condition. These logs are:

l

Historical Alarm Log

l

Historical Trouble Log.

The historical logs contain a time and date stamp of the events surrounding abnormal conditions in the system. The

information displayed with these lists are historical data only and will not contain any current point status. Separate

lists are maintained for alarms and for supervisories/troubles. These lists are displayed by selecting (either the
“ Display Historical Alarm Log?” option or the “ Display Historical Trouble Log?” option from the Main Func.tion Menu.

OPERATOR ACCESS LEVELS

There are four operator access levels available to support the system. They are levels 1 through 4. Level 1 is the
lowest operator access level and does not require a passcode to be entered to access functions identified at this
level. Level 2 through 4 require a passcode of the required level or higher to be entered prior to performing the
passcode protected function. Controlling actions may be classified with access levels 2 through 4. Routine actions
are assigned to low access levels while access level 4 is reserved for special, highly sensitive operations (normally
reserved for Simplex Personnel). Entering a level 4 passcode enables you to access all the functions of the system.

A valid passcode must contain a minimum of 3 digits and not more than 10 digits. The available digits are 0 through

9. Passcodes are specified during order entry; then, programmed during system configuration. When passcodes
are not specified, the following default passcodes are assigned.

LEViL PASSCODE RANK

1 NONE
2 222
3 333
4

xxx

The operator access level defaults to level 1 when power is first applied to the system, after 10 minute:s of keypad

inactivity, and when the user elects to log out. The <SYSTEM RESET> key press has no effect upon the access
level.

The only way to increase the operator access level in the system is to select the “ Change Access Level?” option in

the Main Function Menu. Decreasing the level resets system access level to 1. Increasing the level requires a valid
level 2, 3, or 4 passcode. The user is prompted to enter a passcode. The input is compared to all the vallid system
codes, and the system operator access level is set accordingly. If an invalid code is input, you will be notified with
the message “ ERROR...INVALID PASSCODE” , and will be allowed up to three chances to enter a valid code. After

three unsuccessful tries, the message “ ACCESS DENIED” will be displayed for a short time. The access level will

not be altered, but you will no longer be in the “ Change Access Level” menu option.

LOWEST
SECOND

THIRD (Highest Operator Access Level)

HIGHEST (Normally Used By Simplex Personnel)

If a correct passcode is entered, the message “ ACCESS GRANTED” is displayed. The new operator access level

will be in effect until the keypad is inactive for 10 minutes or you manually reset the level through th’ e “ Change

Access Level” option.

68

While entering a passcode with the keypad, the key presses are acknowledged by a “ beep” . The digits entered are

not displayed. The cursor moves along, filling the position with an X to indicate that a digit has been entered. The
<DEL> key can be used to delete the last digit. The <ENTER> key press is required to enter the passcode into the
system.

The Action Keys, ON, OFF, AUTO, ENABLE, DISABLE and the five Panel Control Keys may have operator access

levels associated with them. If such a key is pressed with an insufficient access level, a message will inform you that
the action was not taken and the key press is ignored. The user will have to select the Main Function Menu option
to increase the access level before using the key. (See Log In Procedure for details.)

The Acknowledge Keys may also require passcodes to acknowledge abnormal conditions. If you press an cACK>
key with insufficient access, an error message will be displayed. The points will scroll with cACK> key pressing to
allow you to view the points on the list, but the points will not be acknowledged. (See Log In Procedure for details.)

POWER UP SEQUENCE

Whenever power is applied to the NDU panel, or when the NDU Master Controller microprocessor has been reset,
the NDU self-tests its memory integrity and verifies card configurations. Next, the NDU displays the system startup

in progress messages, followed by a trouble condition. Battery trouble conditions normally clear automatically.

The green POWER ON LED illuminates immediately after AC power is applied to the NDU. Make sure that the green

LED is illuminated before connecting the battery power harness.

IMPORTANT

To power up the NDU, apply 120 VAC to the unit. Wait until the GREEN POWER ON LED has

illuminated; then, connect the battery power harness.

To power down the NDU, disconnect battery power harness; then, turn the 120 VAC power OFF.

SYSTEM TEST PROCEDURES

NOTE: These procedures should be followed when the system is installed and during periodic testing as required

by code. Check local codes to determine how frequent your system should be tested. Always inform
appropriate personnel that you will be testing the system (city fire depa.rtment, etc.).

LAMP TEST

The “ LAMP TEST” push-button on the operator interface panel is used to determine local lamp failures within the
system. Lamps on the NDU operator interface panel illuminate along with the five function and acknowledge LEDs.
All segments on the LCD also change to squares. Perform the following procedures to determine lamp failures.

1. Press the “ LAMP TEST” push-button. All LEDs should illuminate (lamps should stay illuminated as long as
the push-button is depressed). Holding the push-button in for more than 3 seconds will test the tone-alert.

2. Perform an individual lamp test on all remote LCD annunciators using the key switch on the operator
interface panel.

3. If you find defective lamps/LEDs, contact your local Simplex branch office.

Walk TestTM

Walk TestTM must be conducted at each network node individually. Zones going into Walk TestTM alarm will not be
visible to or annunciated at other network nodes. However, signals at other nodes may be affected if external signal
points are included in the Walk TestTM output lists.

HOW TO TURN A POINT OFF
