- This LED will be illuminated when there is a fault associated with the
main or secondary power supply the following conditions constitute a fault.
Faults are:
➢ Charger failure
➢ Battery voltage low
➢ Battery missing
➢ HCI missing
➢ PSU overload
- The indicator is illuminated when there is a main system CPU fault
present in the FACP. The indicator is latching and is cleared by activating the RESET control. System
fault is caused by
➢ Main CPU failure -> watchdog condition
➢ Software checksum failure
➢ Memory checksum failure
- This LED will be illuminated if there is an earth fault (+ or -) on any of
the signal cables of the system. An earth fault is when the impedance detected between the 0 volt line
of the FACP and earth is less than 50ohm’s. The indicator is non latching and extinguishes when the
current flow drops below the threshold
- When the indicator is illuminated, the FACP is in any of the “Test”
modes.
- This LED will be illuminated when a device/detector is in the pre-alarm
state. Conditions – when at least one sensor has entered the pre-alarm condition. If the pre-alarm is
the highest priority abnormal condition present on the panel – then the sensor in pre-alarm shall be
reported to the LCD. If a higher priority condition is present, then the menu system shall be used to
display the pre-alarm.
