DISARMING
Enter the premises only through the door indicated by your installer as the
entry/exit door. The keypad sounder will be ON. Go to the keypad and enter the
[4 digit access code]. If an error is made entering the code, press the [#] key
and enter the code again. The "Armed" light will go out and the keypad sounder
will stop. A correct access code must be entered before the allowed entry time
expires. The entry delay time may be changed by the installer.
If an alarm occurred while the panel was armed, the "Memory" light and the light
for the zone which caused the alarm will start to flash and will continue flashing for
2 minutes. At the end of 2 minutes, the keypad lights will stop flashing and the
keypad will return to the normal Ready condition.
If you return home and find an alarm has occurred while you were away, it is
possible that an intruder may still be on the premises. Go to a neighbour's and if
your system is monitored, call the monitoring station. They will advise what action
has been taken as a result of the alarm and whether the premises are safe to
enter. If your system is not monitored, call the local police to investigate.
ALARM MEMORY DISPLAY
If the "Memory" light is on, an alarm has occurred since the last time the panel
was armed. The alarm memory will automatically be displayed when the system
is disarmed (see Disarming).
Press the [ ] then [3] keys to display which zone caused the alarm.
The alarm memory will be cleared when the panel is re-armed.
Press the [#] key to return to Ready.
ZONE BYPASSING
Bypassed zones do not cause an alarm. Use zone bypassing when access is
needed to part of the protected area. Also, damaged wiring or contacts on a
zone may be temporarily bypassed until repairs can be made so that the panel
can be armed.
To bypass zones, enter [ ][1][Access Code] and the zone numbers to be
bypassed. i.e. [1] for zone 1, [8] for zone 8. If the [0] key is pressed instead of
a zone number, all zone bypasses will be removed. If the [9] key is pressed,
the last group of zones which was bypassed will be recalled. Press [#] to return
to Ready.
For security reasons, your installer may prevent the bypass command from
operating on certain zones.
The "Bypass" light is ON as long as at least ONE zone is bypassed. Do not
unintentionally bypass zones when arming. Zone bypasses are automatically
cancelled each time the panel is disarmed and must be re-applied before the
next arming.

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
TROUBLE
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.
