6.7 SYSTEM FAULT RESET
6.7.1 FUNCTION
To reset, if possible, a latched System Fault as shown by the front panel "SYSTEM FAULT"
indicator.
The specific cause, or causes, of the "SYSTEM FAULT" indication can be determined by a
"RECALL SYSTEM FAULT" command, or sometimes be seen on the internal diagnostic
indicators.
6.7.2 OPERATING SEQUENCE
From any information display or base display, press:
Note: For a networked panel after pressing SYSTEM a prompt will be given requesting
whether the local panel or a remote panel should be reset. For the remote panel
option a further prompt will be given for the SID of the remote panel. Enter the SID of
the remote panel to be reset.
System Fault Reset may also be effected by the RESET SYSTEM command sequence.
- The "WATCHDOG", "DISPLAY FAULT", and
"SOFTWARE FAULT" LED indicators (on the Main Board)
latch, to assist service personnel during trouble shooting.
- If an FIP loop power fault exists, the FIP immediately
disconnects power to the loop on line 2 (so long as no other
conditions exist that require that power be connected).
The FIP then tests as to whether the loop fault has cleared or
not.
- If a particular fault condition no longer exists, system fault reset
clears that fault indicator.
6.7.3 NOTES
(a) System Fault Reset should only be performed by Service Technicians or authorised
fire safety personnel.
(b) System Fault Reset should only be performed after a "Recall System Fault"
command has been used to determine the cause of the fault and any appropriate
service action has been taken.
(c) If the fault is a network fault then it will be cleared irrespective of whether it is still
present or has cleared. Thus if any faults still exist they will be re-annunciated soon
thereafter.
