Installation Precautions

- Adherence to the following will aid in problem-free installation with long-term reliability:

WARNING - Several different sources of power can be connected to the fire alarm control panel. Disconnect all sources of power before servicing. Control unit and

associated equipment may be damaged by removing and/or inserting cards, modules, or interconnecting cables while the unit is energized. Do not attempt to install, service, or operate this unit until this manual is read and understood.

CAUTION - System Reacceptance Test after Software Changes: To ensure proper system operation, this product must be tested in accordance with NFPA 721993 Chapter 7 after any programming operation or change in site-specific software. Reacceptance testing is required after any change, addition or deletion of system components, or after any modification, repair or adjustment to system hardware or wiring.

All components, circuits, system operations, or software functions known to be affected by a change must be 100% tested. In addition, to ensure that other operations are not inadvertently affected, at least 10% of initiating devices that are not directly affected by the change, up to a maximum of 50 devices, must also be tested and proper system operation verified.

This system meets NFPA requirements for operation at 0-49O C/32-120O F and at a relative humidity of 85% RH (non-condensing) at 30 useful life of the system's standby batteries and the electronic components may be adversely affected by extreme temperature ranges and humidity. Therefore, it is recommended that this system and its peripherals be installed in an environment with a nominal room temperature of 15-27

Verify that wire sizes are adequate for all initiating and indicating device loops. Most devices cannot tolerate more than a 10% I.R. drop from the specified device voltage.

C/86O F. However, the

C/60-80O F.

Like all solid state electronic devices, this system may operate erratically or can be damaged when subjected to lightning induced transients. Although no system is completely immune from lightning transients and interferences, proper grounding will reduce susceptibility. Overhead or outside aerial wiring is not recommended, due to an increased susceptibility to nearby lightning strikes. Consult with the Technical Services Department if any problems are anticipated or encountered.

Disconnect AC power and batteries prior to removing or inserting circuit boards. Failure to do so can damage circuits.

Remove all electronic assemblies prior to any drilling, filing, reaming, or punching of the enclosure. When possible, make all cable entries from the sides or rear. Before making modifications, verify that they will not interfere with battery, transformer, and printed circuit board location.

Do not tighten screw terminals more than 9 in-lbs. Over tightening may damage threads, resulting in reduced terminal contact pressure and difficulty with screw terminal removal.

This system contains static-sensitive components. Always ground yourself with a proper wrist strap before handling any circuits so that static charges are removed from the body. Use static suppressive packaging to protect electronic assemblies removed from the unit.

Follow the instructions in the installation, operating, and programming manuals. These instructions must be followed to avoid damage to the control panel and associated equipment. FACP operation and reliability depend upon proper installation.

Fire Alarm System Limitations

An automatic fire alarm system - typically made up of smoke detectors, heat detectors, manual pull stations, audible warning devices, and a fire alarm control with remote notification capability can provide early warning of a developing fire. Such a system, however, does not assure protection against property damage or loss of life resulting from a fire.

Any fire alarm system may fail for a variety of reasons: Smoke detectors may not sense fire where smoke cannot reach the detectors such

as in chimneys, in walls, or roofs, or on the other side of closed doors. Smoke detectors also may not sense a fire on another level or floor of a building. A second floor detector, for example, may not sense a first floor or basement fire. Furthermore, all types of smoke detectors - both ionization and photoelectric types, have sensing limitations. No type of smoke detector can sense every kind of fire caused by carelessness and safety hazards like smoking in bed, violent explosions, escaping gas, improper storage of flammable materials, overloaded electrical circuits, children playing with matches, or arson.

IMPORTANT! Smoke detectors must be installed in the same room as the control panel and in rooms used by the system for the connection of alarm transmission wiring, communications, signaling, and/or power. If detectors are

not so located, a developing fire may damage the alarm system, crippling its ability to report a fire.

While installing a fire alarm system may make lower insurance rates possible, it is not a substitute for fire insurance!

FCC Warning

Audible warning devices such as bells may not alert people if these devices are located on the other side of closed or partly open doors or are located on another floor of a building.

A fire alarm system will not operate without any electrical power. If AC power fails, the system will operate from standby batteries only for a specified time.

Rate-of-Rise heat detectors may be subject to reduced sensitivity over time. For this reason, the rate-of-rise feature of each detector should be tested at least once per year by a qualified fire protection specialist.

Equipment used in the system may not be technically compatible with the control. It is essential to use only equipment listed for service with your control panel.

Telephone lines needed to transmit alarm signals from a premise to a central monitoring station may be out of service or temporarily disabled.

The most common cause of fire alarm malfunctions, however, is inadequate maintenance. All devices and system wiring should be tested and maintained by professional fire alarm installers following written procedures supplied with each device. System inspection and testing should be scheduled monthly or as required by National and/or local fire codes. Adequate written records of all inspections should be kept.

WARNING: This equipment generates, uses, and can radiate radio frequency energy and if not installed and used in accordance with the instruction manual, may cause interference to radio communications. It has been tested and found to comply with the limits for class A computing device pursuant to Subpart B of Part 15 of FCC Rules, which is designed to provide reasonable protection against such interference when operated in a commercial environment. Operation of this equipment in a residential area is likely to cause interference, in which case the user will be required to correct the interference at his own expense.

Technical Publishing Document PRECAULG.PM6 12/31/96

Canadian Requirements

This digital apparatus does not exceed the Class A limits for radiation noise emissions from digital apparatus set out in the Radio Interference Regulations of the Canadian Department of Communications.

Le present appareil numerique n'emet pas de bruits radioelectriques depassant les limites applicables aux appareils numeriques de la classe A prescrites dans le Reglement sur le brouillage radioelectrique edicte par le ministere des Communications du Canada.

2. Using the Control Panel Control Keys

Control Keys

The control panel provides five control keys, Acknowledge/Step, Alarm Silence, Alarm Activate, System Reset, and Lamp Test.

Acknowledge Step Use the <Acknowledge/Step> key to respond to new alarm or

trouble signals. Pressing <Acknowledge/Step> causes the control panel to do the following:

• silence the control panel sounder;

• change all indicators from flashing to steady;

• send an Acknowledge message to the history file, an optional printer, and an optional ADT-LCD-80; and

• send a signal to silence the sounder on the ADT-LCD-80 and ACS annunciators.

You can also press the <Acknowledge/Step> key to display multiple alarms or troubles. If more than one alarm or trouble exists, the control panel displays the next alarm or trouble for 3 seconds (or until you press <Acknowledge/Step>), then displays the next alarm or trouble.

Alarm Silence Use the <Alarm Silence> key to silence the control panel sounder as

well as sounders connected to Notification Appliance Circuits. Pressing <Alarm Silence> causes the control panel to do the following:

• turn off the control panel sounder;

• turn off all silenceable output circuits;

• light the Alarm Silenced LED; and

• send an Alarm Silenced message to the history file, optional printer, and an optional ADT-LCD-80.

Alarm Activate Use the <Alarm Activate> key to test notification appliances. Press

and hold the Alarm Activate switch for 2 seconds (to prevent accidental activation). The control panel does the following:

• turns on all silenceable NACs;

• turns off the Alarm Silenced LED; and

• sends a Manual Evacuate message to the history file, optional printer, and an optional ADT-LCD-80.

System Reset Use the <System Reset> key to reset the control panel. Press <System

Reset> and the control panel does the following:

• turns off all alarm-activated M500CH modules and NAC circuits;

• breaks resettable power to four-wire detectors; and

• sends an All Systems Normal message to the history file, optional printer, and an optional ADT-LCD-80.

Any alarm or trouble that exists after a System Reset reactivates NACs, control outputs, and panel audio and visual indicators.

Lamp Test Use the <Lamp Test> key to test the control panel LEDs and sounder.

Press and hold <Lamp Test> and the control panel does the following:

• lights all control panel LEDs;

• turns on the control panel sounder; and

• lights all segments of the LCD display.

3. Operating Modes

Normal Operation

The system operates in Normal mode when no alarms or troubles exist. In Normal mode, the control panel displays a system message as follows:

YOUR CUSTOM FORTY CHARACTER MESSAGEHERE ALL SYSTEMS NORMAL11:30A TUE 02/11/97

Figure 3 All Systems Normal Message

In Normal mode, the control panel does the following functions at regular intervals:

• Polls all Signaling Line Circuit (SLC) devices and the four NACs to check for valid replies, alarms, troubles, circuit integrity, and so on.

• Checks power supply troubles and batteries every 10 seconds.

• Sends a supervisory query on the ADT-LCD-80 and verifies proper response.

• Refreshes the LCD and the optional ADT-LCD-80 display and updates time.

• Scans the keypad for a System Reset or an Enter key press.

• Performs a detector automatic test operation.

• Tests system memory.

Note: M500CH modules report both open and short circuit messages.

Trouble Operation

The system goes into Trouble mode when the control panel detects an electrical or mechanical fault. With no alarms, a control panel in Trouble mode does the following:

• Produces a pulsed audible tone;

• The System Trouble LED flashes;

• The trouble relay activates (MPS-400, TB5); and

• Sends a message to the LCD display, an optional ADT-LCD-80, an optional printer, and the history file.

Figure 4 shows a typical Trouble message:

3. Operating Modes Fire Alarm

If the trouble clears (before or after pressing <Acknowledge/Step>), the control panel sends a Clear Trouble message to the printer. Figure 5 shows a sample Trouble Message:

TROUBL CONTROL MODULE ADDRESS 21 Z00 OPEN CIRCUIT 08:10A 08/20/95 M21 TROUBL CONTROL MODULE ADDRESS 22 Z00 OPEN CIRCUIT 08:12A 08/20/95 M22

Figure 5 Sample Trouble Message

If all troubles clear and no supervisory or fire conditions exist, the control panel does the following:

• Returns to Normal mode;

• Sends an “All Systems Normal” message to the LCD display, the history file, an optional ADT-LCD-80, an optional printer; and

• Restores troubles automatically even if troubles are not acknowledged.

Pressing <Alarm Silence> when only troubles exist, gives the same result as pressing <Acknowledge/Step>. The Alarm Silenced LED does not light unless an alarm exists in the system.

If multiple trouble conditions exist in the system, the LCD and optional ADT-LCD-80 displays automatically step through each trouble event every 3 seconds in the following order:

1. Alarms, in order of address;

2. Supervisory, in order of address; or

3. Troubles, in order of address.

Press <Acknowledge/Step> and the display stops on the current trouble event for 1minute. Press <Acknowledge/Step> to continue.

Fire Alarm

The system goes into Fire Alarm mode when the control panel detects a fire alarm. During Fire Alarm mode, the control panel does the following:

• Produces a steady audible tone;

• Activates the System Alarm relay (MPS-400, TB3) and flashes the System Alarm LED;

• Displays Alarm in the status banner on the LCD display;

• Latches alarms so they cannot clear until the alarm initiating device returns to its normal condition and the operator resets the control panel;

• Initiates any Control-by-Event actions;

• Starts timers (such as Silence Inhibit, Auto Silence); and

• Activates the general alarm zone (Z00).

Table 3 Non-Alarm Points

Trouble Monitor Point Operation

Trouble Monitor-type M500M modules monitor remote power supplies or other external equipment. These types of M500M modules operate like troubles—but with the following differences:

• The LCD display status banner displays “Active”;

• The type code is “Trouble Mon”;

• The modules latch—until the troubles are returned to normal condition and an operator resets the control panel; and

• M500M modules can have Control-by-Event.

Unimode 400 Operations PN 50709:A 10/20/97 7

3. Operating Modes Notification Appliance Circuit (NAC) Operation

Notification Appliance Circuit (NAC) Operation

The four NACs (TB7-TB10 on the MPS-400) have Control-by-Event and trouble functions like M500CH addressable modules on the SLC loop. NAC circuits differ from M500CH modules in the following ways:

• Addresses (last three characters in LCD field) are B01, B02, B03, or B04;

• The default type code field is “Bell Circuit”; and

• Control panel NACs, except those controlled with M500CH modules, can be used for coded functions (March Time, California Code, Temporal, and Two-stage).

Control-By-Event Operation

Note: Zones F0-F9 are reserved for special functions such as cross-zoning (refer to the Unimode400 Programming Manual).

Control-by-event (CBE) control is done through 99 software zones. Each input point (detector, M500M) and output point (M500CH, NAC) can be programmed to list up to five software zones. Non-Alarm or Supervisory points do not activate software zone Z00 (general alarm). You can list zone Z00 for output points, but you do not need to list Z00 for input points.

Input and output devices with listed software zones work as follows:

• Inputs – When an input device (detector or M500M) activates, so do all software zones listed to the input device.

Note: Refer to Appendix A for more information about releasing functions.

• Outputs – When a software zone activates, the output device turns on.

CBE Example Detector D102 lists zone Z05. B01 lists zone Z05 and zone Z07.

1. Detector D102 activates.

2. Zone Z05 activates.

3. B01 activates.

Releasing Functions

Overview Zones R0-R9 are reserved for releasing zones—providing up to ten

independent releasing operations. Each releasing zone includes the following options:

Option Description

Cross-zoning Select one of three types of cross-zoning. Refer to Table 5. Delay Timer Select a 0–60 second delay before activating a zone. Abort An abort switch-type code used to abort activation of a zone. Manual Release Allows immediate zone activation by overriding the abort function,

cross-zone function, and delay timer.

Man. Rel. Delay Same as Manual Release, except releasing occurs 10 seconds after

“Man. Rel. Delay” is activated.

Soak Timer Automatically shuts off the releasing device. Select 0001-9999 seconds

for a Soak Timer or 0000 seconds for no Soak Timer.

Second Shot Reactivates release output after the Soak Timer times out.

Table 4 Cross Zoning Options

Releasing Functions 3. Operating Modes

Using Cross Zoning Options Cross Zoning lets you program the control panel to

activate a releasing zone after two initiating devices are tripped. (If not using Cross Zoning, set CROSS= to N.) Table 5 contains a summary of the types of cross zoning and the conditions for activating a releasing zone.

Type Activates when...

Y Two or more detectors, all mapped to one of the ten releasing zones (R0-R9), are

tripped.

Z Two or more detectors, mapped to two different software zones and one of the ten

releasing zones (R0-R9), are tripped.

H At least one smoke detector and at least one heat detector, all mapped to one of the

ten releasing zones (R0-R9), are tripped.

Table 5 Cross Zoning Types

Note: Only the first non-special zone listed in the zone map is used to determine Cross=Z.

Cross Zoning Example Table 6 lists examples of devices mapped to releasing zones

(ZR1 stands for Releasing Zone 1).

Table 6 Devices Mapped to Releasing Zones

The following explanations apply to the examples listed in Table 6:

Cross=N An alarm from any detector activates the releasing circuit.

•

Cross=Y An alarm from any two detectors activates the releasing circuit.

•

Cross=Z Release requires the activation of two detectors mapped to different

• zones: D101 and D102 cannot activate the releasing circuit because both detectors are mapped to Z01; D101 and D103 can activate the releasing circuit because they are mapped to different zones.

Cross=H Release requires activation of heat detector D104 and one smoke

compensation that can be safely applied, the control panel reports a special trouble condition, per national fire code standards. This condition also activates if the detector remains at very high or very low measured air levels for an extended time.

The control panel performs an automatic test of each detector every 256 minutes. Failure to meet the test limits causes an AUTO TEST Fail trouble.

The control panel monitors hardware device type codes (500 Series detectors, 200 Series detectors, 3251 detectors, M500M, and M500CH) for each installed device at regular intervals (an interval can take up to 30 minutes for full capacity system). If a mismatch of type compared to the program occurs, the control panel generates a point trouble labelled Invalid Type.

A global program selection to prevent detector LEDs from blinking during normal operation. A typical application is a sleeping area where a blinking light can distract people. As a standard function, the control panel allows all LEDs to turn on in alarm.

The control panel performs alarm verification on programmed 500Series, 200 Series, and 3251 intelligent smoke detectors. The verification time is a global program selection of 0–30 seconds. Each detector includes a verification counter, which displays the number of times that a detector entered verification but did not time-out to alarm. The counter increments to 99 and holds.

If programming a control panel for an ACTION Pre-Alarm, the display remains the same, but the word “Action” replaces “Alert”. The control panel latches for ACTION Pre-Alarms and applies the programmed control functions.

Time Functions

Overview The control panel includes a real-time clock that provides time-of-day, date, and day-

of-week. The clock includes a lithium battery backup. Time normally displays in a 12-hour time format with month/day/year. Table 8 contains descriptions and typical uses for time functions.

Time Function

Time Control Command

Description Typical Uses

Zones F5 and F6 are reserved for control-by-time special functions, intended for ancillary (non-fire) applications (such as lighting control, setting a thermostat, and so forth).

For example, program zones F5 and F6 to activate at one time of day and deactivate at another time, on certain days of the week. You can turn a non-fire control point on and off, by using zone F5 or F6.

Day/Night Sensitivity Adjust

Holiday The control panel reserves zone F7

If a 1551/2551, 1251/2251, or 3251 detector CBE lists zone F5 or F6, the control panel sets the detector sensitivity to the minimum (low) setting when zone F5 or F6 is activated by the programmed date/ time in its CBE. When zone F5 or F6 deactivates, the detector sensitivity returns to the programmed setting.

for setting holiday dates (up to 9 days). When the current date matches any of the nine holiday dates, the control panel activates zone F7.

For day/night sensitivity use, consider zones F5 and F6 as Day zones.

Other uses for zone F7 include: a special day-of-year control; or an 8th day in programming zones F5 and F6.

Operating Coding Functions

Zone F8—reserved for NAC coding functions—is only used by panel NAC circuits listing zone F8. You can select one of the four code types listed in Table 9:

Code Signal

March Time (default) 120 PPM (Pulses Per Minute) Two-Stage Alert signal – 20 PPM; General alarm signal: Steady on California 10 sec. on, 5 sec. off, repeats Temporal 0.5 on, 0.5 off, 0.5 on, 0.5 off, 0.5 on, 1.5 off, repeats

Table 9 Zone F8 Type Codes

Notes on using coding functions:

M500CH modules Zone F8 does not work if listed in the CBE of M500CH modules. Two-Stage When an alarm occurs, an NAC programmed for two-stage, and not

activated by another zone, pulses at 20 PPM. After 5minutes, the NAC changes to steady on unless you press <Acknowledge/Step>. Pressing <Alarm Activate> on the control panel changes the NAC pulse to steady. ICM-4/ICE-4 modules do not support Two-Stage and turn on steady.

ICM-4/ICE-4 modules To enable California Code, cut D35 on the ICM-4 modules. If

D35 is not cut, ICM-4/ICE-4 modules turn on steady.

Presignal/Positive Alarm Sequence (PAS) Operation

Zone F0 is reserved for Presignal functions. Zone F0 can be used to delay control points until an operator verifies an active control point. If including zone F0 in an M500CH or NAC CBE list, zone F0 overrides all other CBE actions. Detectors and monitor modules must list zone F0 in the CBE to be included in the Presignal/PAS operation.

Table 10 Presignal Operation

At the first alarm, a programmable 0–180 second timer starts. If a Signal Silence occurs, the timer stops. If the delay timer expires, manual activation will activate outputs mapped to zone F0. The System Alarm relay, the 4XTM Polarity Reversal Alarm Output, and the 4XTM Municipal Box Output delay if PAS is selected, but do not delay for Presignal operations

2251, or 3251 smoke detectors for the Alarm Verification time. If another point alarm occurs during the Alarm Verification time, the control panel dumps the timer and activates the alarm. If a time-out and an alarm exist, the initiating device CBE executes all standard functions. If at time-out an alarm no longer exists in the alarm initiating devices, the control panel increments a verification counter (1-99) for the device and returns to normal operation.

Table 11 Special System Timers

If an alarm originates from a monitor point with a waterflow type code, the control panel disables the Alarm Silence switch. Refer to the Unimode400 Installation Manual for information on Waterflow Circuits.

Disabled input points do not cause an alarm or any Control-by-Event activity. The control panel does the following:

• holds all disabled output points in the off-state; and

• handles all disabled points as troubles, but displays DISABL in the status banner.

Caution: Disabling a zone disables all input and output devices associated with the

zone.

Style 6 Operation The control panel will detect a trouble in an SLC wired and programmed for Style 6 or

Style 7 and drive both ends of the line to maintain communication over the loop. The trouble latches and displays on the panel as a Style 6 trouble type until you press <System Reset>. Style 7 requires use of M500X modules.

AMG-1/AMG-E Overview

AMG-1/AMG-E Operating Features

An AMG-1/AMG-E produces tones and messages. You can set up an AMG to automatically activate programmed tones or messages through an EIA-485 communications circuit loop or manually select tones and messages. Operating the AMG involves viewing the LEDs for status information and operating the microphone and switches.

Each AMG-1 contains one output channel. To set up a secondary channel for dual channel operation, install an additional AMG-1 or AMG-E. Each AMG can directly drive up to fifty audio amplifiers.

An AMG can store and use up to four digitally-recorded voice messages. Each voice message can be up to 24 seconds long. Table 19 contains details of the two types of digital messages available:

Type of Message Hardware Requirements How to Create

Factory VROM memory chips Pre-recorded, factory-supplied. Field Programmable VRAM-1 memory chips Record directly into the AMG via

Selecting AMG Group Functions 5. Voice Alarm Systems

Selecting AMG Group Functions

Selecting Factory-Programmed Messages (VROM) Operation of tones and

messages available in a voice alarm application depends on the following:

• The type and number of VROM chips installed; and

• The functional groups selected by AMG-1 DIP switch settings.

Note: If a digitally-stored voice message fails, the AMG-1 automatically switches to the primary evacuation tone, and generates a trouble signal.

Installing one or two optional VROMs lets you select a factory-programmed message by setting rocker switches 6, 7, and 8 on the AMG-1. (Refer to Selecting AMG Tones and Messages.) For example, Figure 28 on page 27 shows the text of factory-recorded VROM-101 message in a male voice:

“MAY I HAVE YOUR ATTENTION PLEASE. MAY I HAVE YOUR ATTENTION PLEASE. THERE HAS BEEN A FIRE REPORTED ON YOUR FLOOR. THERE HAS BEEN A FIRE REPORTED ON YOUR FLOOR. PLEASE PROCEED TO THE STAIRWAYS AND EXIT THE BUILDING. DO NOT USE THE ELEVATORS.”

Refer to Document 15945 for a complete description of all VROM Series messages.

Note: A VRAM message can be up to 24 seconds long.

VRAM-A Enable (if installed)

Recording Custom Messages (VRAM option) You can record custom messages

through the AMG-1 microphone or load a message recorded on an audio cassette recorder. To do so, you must install at least one VRAM chip in U12 (VRAM-A) or U13 (VRAM-B) on the AMG-1 (Figure 29). For example, if the AMG-1 contains a VRAM-A chip in U12, record a message as follows:

1. If loading a message from a tape recorder, connect the tape recorder to J1 on the AMG-1. (Figure 29)

2. Set the Voice RAM Enable rocker switch 4 (VRAM-A) or 5 (VRAM-B) on the AMG DIP Switch (SW2) to the ON position. The AMG-1 starts to record input to VRAM-A or VRAM-B from a tape recorder or from the AMG-1 microphone.

3. Record a message through the AMG-1 microphone or load a message from a tape recorder connected to J1.

4. When finished recording or loading the message, set the Voice RAM Enable switch to the OFF position.

ATG-2 Audio Tone Generator 5. Voice Alarm Systems

ATG-2 Audio Tone Generator

ATG-2 Overview The ATG-2 provides user-selected tones for single or dual channel output. The ATG-2

provides several ways to page.

• Direct paging – The ATG-2 microphone with a button switch lets you page through primary and secondary speaker circuits channels. If used with an optional FFT-7, the ATG-2 also lets you page through the system from telephones installed throughout the installation.

Note: For more information on ATG-2 configuration, refer to the Voice Modules Section of the Unimode400 Installation Manual.

• Remote paging microphone – You can also set up the ATG-2 to pass-through an audio message (or tone) received from an AMG-1 or another ATG-2. In this configuration, the ATG-2 serves as an alternate (remote) paging location for the AMG-1 or main ATG-2. The ATG-2 provides override paging capabilities from the ATG-2 microphone. All communications go through NAC 1 using ACS mode (Refer to the Unimode400 Installation Manual for instructions.) connected to the control panel—unless set up for remote paging microphone operation.

Figure 32 shows the operating features of the ATG-2:
