armed, and HIGH when any enabled partition is disarmed. The remaining triggers are
normally LOW and go HIGH when the corresponding condition occurs in at least one enabled
partition. The fire and burglary/audible panic alarm triggers remain HIGH until a [User
Code] + [OFF] is entered in all enabled partitions that display these conditions. The silent
panic/duress trigger works the same way, except that it is momentary when initiated by
duress. The fire supervisory and trouble triggers remain HIGH until the underlying faults
are corrected and the [User Code] + [OFF] is entered in all enabled partition(s) that
display these conditions.
When a Long Range Radio is installed, configure the sense select for zones 1 and 2 in the
Long Range Radio to activate on +5V (positive trigger). This is necessary to prevent false
alarms from occurring. Refer to the installation instructions provided with your radio for
instructions on setting the zone 1 and 2 levels.
Figures 12-5a, b, and c show how to make connections to the 7720, 7720ULF, and 7920SE
