Keyswitch Operation With System Disarmed and No Alarms Present:
A momentary short across zone 7 will arm the partition in the AWAY mode, and a short held
for more than 10 seconds will arm the partition in the STAY mode. A subsequent short will
disarm the partition. The keyswitch LEDs indicate the partition status (see table below).
Faulted zones must either be corrected or bypassed before the system will arm.
Keyswitch Operation With Alarms Present:
A momentary short across Zone 7 will silences alarm bell and keypad sounds, and disarms
the system if it was armed. The keyswitch LEDs provide a memory of alarm indication (see
table below). A subsequent short across Zone 7 will clear the alarm memory indication and
reset 2-wire smoke and glassbreak detectors (if used).
