- 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.
