TROUBLE DISPLAY

The PC2500 continuously monitors a number of possible trouble conditions. If

one of these conditions occurs, the keypad sounder will beep quickly twice every

10 seconds and the keypad "Trouble" indicator will light. Pressing any key on the

keypad will silence the beeper but the "Trouble" light will remain on until the

trouble condition is cleared. If you cannot determine the cause of the trouble

condition, call your installer for assistance. Press the [ ] then [2] keys to display

the type of trouble. The zone lights indicate the type of trouble condition.

ZONE LIGHT

1 .............. Defective Stand-by Battery

2 .............. AC Power Failure (see Note below)

3 .............. Foil Circuit Trouble

4 .............. Telephone Line Problem

5 .............. Unsuccessful Communication Attempt with Monitoring Station

6 .............. Bell Circuit Failure

7 .............. Smoke Detector Circuit Trouble

8 .............. Loss of Time on System Clock

Press the [#] key to return to Ready.

Note: The keypad buzzer will not sound for AC failure until there is also a low

battery condition. The "Trouble" light will come ON as soon as AC fails

and will remain on until AC restores.

If your system is equipped with smoke detectors or other fire alarm detectors, use

the following instructions for resetting an alarm. Before resetting a fire alarm

signal, be sure you know the source of the alarm and that there is no danger (see

Evacuation Planning elsewhere in this manual).

The system bell/siren alarm signal pulses 2 seconds ON and 2 seconds OFF

when the alarm is generated from the fire circuit. The transmission to the

monitoring station is delayed by 30 seconds. The alarm may be silenced and the

transmission delayed for 2 minutes by pressing any number key on the keypad. If

the detector causing the alarm is reset before the 2 minute delay expires, no

further alarm will occur. If the detector is not reset, at the end of the delay the

alarm will start again and the transmission will occur in 30 seconds if a keypad

key is not pressed.

An immediate fire alarm signal and transmission is generated by holding down

the [1] and [3] keys at the same time for 2 seconds.

Some smoke detectors require entering a keypad command to reset them after an

alarm. Press [ ] then hold down the [4] key for several seconds. If the smoke

has cleared, the smoke detector will reset and the fire zone light will go out when

the [4] key is released. If the smoke has not cleared from the detector, open a

window or door and fan clean air into the detector and try resetting again.
