10 XR20 Arming and Disarming
All/Perimeter System Disarming
Disarming: While the system is armed, you can only enter the
premises through an entry/exit delay door without causing an
alarm. After opening the door, the Security Command keypad
sounds a prewarn tone to remind you to disarm the system. You must
disarm the system before the prewarn tone expires or an alarm on
the door zone will occur.
During the prewarn tone, the keypad displays ENTER CODE:. Enter
your user code to disarm the system.
Alarm Display: After disarming, the keypad displays any zones that
tripped or any transmission problems that occurred during the
armed period. All burglary zones are then disarmed and any
bypassed zones are automatically reset.
Disarmed Message: The keypad displays ALL SYSTEM OFF after the
system disarms.
Central Station Report: A report of the system disarming can be
transmitted to the central station. This is optional and can be
programmed for you at any time.
Disarming an All/Perimeter System
1. During the entry delay time, the keypad displays ENTER CODE:.

Disarming During an Alarm
1. While the alarm bell or siren is sounding, enter your user code.
The keypad displays DISARM SILENCE.
2. Press the Select key under DISARM to disarm the system and
silence the alarm.
The keypad next displays ALL SYSTEM OFF to confirm the
system is disarmed.
3. Press the Select key under SILENCE to stop the bell or siren but
NOT disarm the system.
If you do not press any Select key, or you press the COMMAND
key, the system will automatically disarm and silence the
alarm.
Note: If your system is programmed to send an Abort (alarm cancel)
report to the central station, selecting DISARM will send this report
to the central station. Be sure that you want the alarm message to
be cancelled BEFORE deciding to disarm the system. If you do not
want to disarm the system and send the abort report, press SILENCE
to only turn off the alarm bells.
