TROUBLE DISPLAY

The PC2550 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 ............ Day 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.

SMOKE DETECTOR AND FIRE ALARM RESET

If the Fire Alarm sounds at night, do not investigate the alarm: follow your

evacuation plan immediately. Go to a neighbor and call the fire department.

When a Fire Alarm is generated, the bell or siren will sound with a pulsing tone.

Transmission of the fire alarm to your monitoring station is delayed for 30 seconds to

allow you to cancel possible false alarms. To silence the alarm, press the [#] Key.

When the [#] Key is pressed, the system will delay transmission of the fire alarm for

an additional 90 seconds. The 90-second delay is intended to allow you to reset the

smoke detectors after a false alarm.

If the smoke detector is reset and remains reset after the 90-second delay, a fire alarm

will not be transmitted to the monitoring station.

If the smoke detector is reset but goes into alarm again after the 90-second delay, the

fire alarm will sound again and the process described above will repeat. A fire alarm

will be transmitted to your monitoring station after 30 seconds if it is not silenced by

pressing the [#] Key.

Smoke detectors installed on your system may be reset after a false alarm using the [ ][4]

command. To reset smoke detectors to normal, first clear all products of combustion from

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

are clear of smoke, they will return to normal. If the detectors still have smoke in them,

the alarm will sound again. If the alarm sounds again, first ensure that there is no threat

of fire; you may then silence the alarm and reset the smoke detectors.

An immediate fire alarm signal and transmission may be generated by holding

down the [F] key for 2 seconds.
