An alarm is triggered when any of the detectors on a zone circuit sense a fire or a manual
call point is manually operated.
Each zone operates in isolation to the others.
If a zone/s circuit/s have been disabled the FACP is prevented from initiating an alarm
condition on that zone circuit.
If a lamp test is in progress when an incoming alarm is recognised it will be aborted.
If the FACP is in programming mode when an alarm is recognised, then programming mode
is aborted.
When the FACP is in the fire alarm condition, then the fire output will be activated immediately
Associated with the fire output is the fire output on indicator.
The fire output can be disabled (isolated). If the fire output is disabled, then it is not activated as
