- When this indicator is lit, the FACP is in the fault condition. The fault
condition is non latching.
Sources of faults are:
➢ Loop devices – missing, type mismatch, out of calibration / out of maintenance range,
extra (or unexpected device), device related faults (esp. Hochiki)
➢ Analogue loops – short circuit, open circuit or over current
➢ Monitored inputs with open circuit or short circuit conditions
➢ Monitored outputs – with open circuit or short circuit conditions
➢ Main power supply faults – mains missing, charger fault
➢ Secondary supply faults – low battery voltage, missing battery
➢ High Current Interface (HCI) faults – missing, overload
➢ Onboard module faults – missing, failed
➢ Add-On faults – missing, failed, type mismatch
➢ Main CPU failure -> watchdog condition
➢ Software checksum failure
➢ Memory checksum failure
- When this indicator is lit, the FACP is in the Disable (or isolate)
condition. The disable condition is latching.
Entities which can be disabled are:
➢ Zones – to provide an option to distinguish between zone inputs (sensors, detectors etc)
and zone outputs (sounders, beacons, monitored outputs)
➢ Sensors – loop based
➢ Loop devices – where the inputs have been configured as alarm initiating
➢ Sounders – loop based and monitored outputs
- When this indicator is lit, the FACP has had Alarm conditions silenced
by the use of the “Silence/Resound Alarm” button. The condition is latching until another alarm is
sounded or the alarm conditions are cleared.
