1. INTRODUCTION

The FA-1025U is a supervised 5 zone 24VDC Fire Alarm Control Panel.

The panel provides the following features:

- 5 class B detection zones

- 2 class B signal zones, 1.25A per zone

- Alarm and trouble relay contacts

- Remote trouble indication

- Remote supervised alarm annunciation

- Individual zone silence/disconnect switches

- Trouble silence switch

- Subsequent alarm operation

- LED indicators for zone Alarm and Trouble, A.C. On, Battery Fault, Ground Fault,

Remote Lamp Fail, Common Trouble, Signal Trouble and Signal Silenced

2. MECHANICAL INSTALLATION

The panel can be surface or flush mounted. Refer to Figure 1 for dimensions.

For surface mounting, mark the location of the four mounting holes. Install the top two screws into

the wall and place the panel over the screws. Install the bottom screws, and tighten down all four

screws.

For flush mounting, make the wall cut-out according to the panel dimensions. Remove the control

panel door. Mount the flush mounting trim (MODEL FA-102TRU) to the back box using the screws

and nuts provided with the flush mounting kit. Re-install the door on top of the flush trim. The cam

lock may require a minor adjustment in order to compensate for the flush trim.

3. FUNCTION SELECTION

The following jumpers are available for function selection, refer to Figure 2 for location;

JW1 Cut for normally open trouble contacts.

JW2 Cut for normally closed trouble contacts.

JW3 Cut to enable common alarm relay to de-energize if signal silence switch is activated.

JW6 Cut if 60 second signal silence inhibit is not required (Signals can be manually

silenced any time if cut).

JW7 Cut to enable lamp supervision for the remote annunciator alarm zones.

4. WIRING

4.1 DETECTION ZONES

The system has 5 detection zones. Refer to Figure 3 for wiring instruction and to Figure 4 for wire

size.

4.2 SIGNAL ZONE

There are 2 signal zones available for bells and horns providing 1.25A per zone of signal power.

Refer to Figure 3 for wiring instruction and to Figure 5 for wire size.

4.3 ALARM AND TROUBLE RELAYS

Alarm and trouble relay contacts are provided. Refer to Figure 6 for contact location and

designation.

4.4 REMOTE ANNUNCIATION

Annunciation outputs are provided for alarm, remote trouble indicator and buzzer. Cut JW7 to

enable lamp supervision for the remote annunciator alarm zones. Refer to Figure 6 for wiring

instruction.

4.5 A.C. POWER AND BATTERIES

The A.C. power is connected to the terminal block above the transformer.

Use GEL CELL or SEALED LEAD-ACID type of batteries only. Connect the batteries after power

up. Use 24V 4AH batteries for 24 hours standby and 5 minutes of alarm.

ELECTRICAL RATING: 120V, 60 Hz, 1A/ 240V, 50 Hz, 0.5A

BATTERY CHARGER: 200mA MAXIMUM CHARGING CURRENT

5. TROUBLE INDICATORS AND CONTROL

Refer to Figure 2 for the location of indicators and control.

5.1 COMMON TROUBLE LED

The yellow common trouble LED will flash for any trouble in the panel.

5.2 COMMON TROUBLE BUZZER

The common trouble buzzer will sound intermittently for any trouble.

5.3 ZONE TROUBLE LED

The yellow zone trouble LED will illuminate steadily for open loop in the zone wiring.

5.4 TROUBLE SILENCE SWITCH

Operating this switch will silence the common trouble buzzer. If there is no trouble condition and

the switch is in the silence position, the buzzer will sound continuously.

-3-

5.5 BATTERY FAULT LED

Battery removal, low voltage and open battery leads will turn on the yellow battery fault LED and

the common trouble LED.

5.6 GROUND FAULT LED

Any ground fault of 10K ohms or less will turn on the yellow ground fault LED steadily, flashing

the common trouble LED and sounding the common trouble buzzer intermittently.

5.7 REMOTE LAMP FAIL LED

Any open on the supervised remote annunciator wiring will illuminate the yellow remote lamp fail

LED steadily, flash the common trouble LED and the common trouble buzzer will sound

intermittently.

5.8 SIGNAL TROUBLE LED

The yellow signal trouble LED will illuminate steadily for any open or short.

(LED's are located behind the deadfront panel.)

6. SEQUENCE OF OPERATION

Refer to Figure 2 for the location of indicators and controls.

6.1 NORMAL

All indicators are normally OFF except for the green A.C. On LED.

6.2 ALARM

A red zone alarm LED will illuminate steadily for incoming alarm.

6.3 SIGNAL SILENCE

If the 60 second signal silence inhibit is selected, the signals cannot be silenced for 60 seconds

after the first alarm initiation. Once the 60 seconds have expired, pushing the signal silence

switch, which correspond to the zone in alarm, to the right will silence all the bells and horns.

An alarm on the other zone will resound the signals (subsequent alarm). Pushing the other signal

silence switch to the right, after a subsequent alarm will silence the panel. Once the signals have

been silenced, the signal silenced LED will illuminate. If the switches are in the off normal

position to the right while there is no alarm condition, the panel will indicate trouble.

6.4 RESET

Operating the reset switch will restore all latched functions in the panel. The smoke detectors will

reset if all products of combustion are cleared from their chambers.

7. SYSTEM CHECKOUT

BEFORE TURNING POWER ON:

1. Check all external wiring for opens, shorts or grounds.

2. Check that transformer cables are securely connected.

3. Check the A.C. power wiring for proper connection. DO NOT connect batteries in order to

prevent sparking.

4. Check that all switches are in the normal position to the left.

8. POWER UP AND TROUBLESHOOTING

1. After completing all of the system checkout procedures, power up the panel. The A.C. On LED

should illuminate.

2. The trouble buzzer should sound intermittently, the common trouble LED flash, indicating

battery fault.

3. Connect the batteries carefully, observing the correct polarity.

4. The common trouble LED should extinguish. If the common trouble LED stays on, check the

front panel for the illumination of the following LEDs;

a) BATTERY LED - battery voltage may be too low, below 20.4V.

b) GROUND FAULT LED - indicates a ground on one or more of the extended wires.

c) REMOTE LAMP FAIL LED - there is a faulty LED at the remote annunciator.

d) ZONE TROUBLE LED - indicates an open loop or a signal silence switchisintheoff

normal position to the right.

e) SIGNAL TROUBLE LED - indicates an open loop or short in the signal zone.
