- Aux 12V Fault
Indicates that an Auxiliary 12V Output has failed. The cause of failure will need investigating and
rectifying.
- Aux 24V Fault
Indicates that an Auxiliary 24V Output has failed. The cause of failure will need investigating and
rectifying.
- Earth Fault
Indicates that a fault has occurred with the system earthing.
- Fault of Panel X
Indicates that the panel at address X (1 to 32) is in a fault condition.
This line is alternated every 2 seconds with a line describing the nature of the fault.
-
Micro CRC Fault and NVRAM CRC Fault
Indicates that the panels internal self check procedures has detected an error.
- Watchdog Reset
This indicates that the microprocessor inside the fire panel has failed and has been restarted by the
watchdog circuit. If the circuits inside the panel have been damaged, it may not be possible for the
watchdog circuit to successfully restart the fire panel system, in which case the above message may
NOT appear. However, any devices connected to the fault relay will be triggered. The ‘SYSTEM
FAULT’ LED will be illuminated and the internal buzzer will be sounding.
If the panel has ‘crashed’ completely, fire cover will be lost. This will need rectifying immediately.
If the microprocessor has been successfully restarted, the ‘
Watchdog Reset ’ message will appear
on the LCD and the panel will function as normal. The reason for failure will need investigating by
a fire alarm engineer.
