Terminate Auxiliary Outputs with Hardware/Alarms

Door and auxiliary inputs can be programmed to trip auxiliary output relays on an alarm event. This excludes
pre-alert relays. Auxiliary output relays can be connected to alarm panels, CCTV systems etc.
As an example, a forced entry detected by a door input could be programmed to trip an auxiliary output that
initiates a CCTV system to record the intrusion at the door.
Auxiliary output relays may also be used to control hardware with an associated time zone, such as scheduling
the locking/unlocking of a door, which does not have a reader, to a defined time zone.
Important
Do not assign a time zone to an auxiliary output if the output has previously been assigned to an alarm
event. The alarm has priority over the time zone.
