USING THE KEYSWITCH
General Your system may be equipped with a keyswitch for use when arming and
disarming. A single red light on the keyswitch plate indicates the status of
your system as follows:
OFF = Disarmed, Not Ready for Arming
SLOW FLASHING = Disarmed, Ready for Arming
RAPID FLASHING = Armed STAY or AWAY
Arming
To arm in the AWAY mode, turn key to right for 1/2 second.
To arm in the STAY mode, hold key turned to right for more than one
second.
The keypads will beep twice (AWAY mode) or 3 times (STAY mode) and
the keyswitch light will flash rapidly.
Disarming
To disarm the system turn the key to the right and release.
If an alarm has occurred during the armed period, the keyswitch's light will
not flash on disarming (thus indicating memory of an alarm). Turning the
keyswitch key to the right a second time after disarming can clear the alarm
from memory, but it is advisable, instead, to refer to a keypad to diagnose
and clear any problem, and to subsequently clear alarm memory.
See the
previous page for more about alarm memory.
