DEALING WITH FAULTS
4.2.1 WHAT IS A FAULT?
A fault is any situation which prevents the panel from correctly performing its functions.
Possible faults include defects in external wiring or power feed to the detectors, faulty
detectors, component failures, faulty charger and low battery voltage.
In normal operation the only lit LED indicator should be the green "MAINS ON". For New
Zealand mode F4000 panels the green "NORMAL" LED indicator should also be ON. If
other indicators are active, or the "NORMAL" LED is OFF or flashing, this should be reported
and promptly investigated.
4.2.2 RESPONDING TO FAULT SIGNALS
If a fault occurs, the fault sounder will operate (steady tone) unless it is configured to not turn
on. If a zone fault exists, the FFCIF "FAULT" LED will be ON. If a system fault exists, the
"SYSTEM FAULT" LED will be ON. If a Battery/Charger fault exists, the "CHGR/BATT
FAULT" LED will be ON or FLASHING.
If the LCD keypad is at the "base display", the fault action text programmed by the installer
will be displayed.
The "CLEAR" key or "ACK" key may be pressed in order to silence the panel's fault sounder
until a service technician arrives. When the sounder is silenced, any fault action text display
will be cleared also.
If a fault or other off-normal condition exists, the LCD will display the number of Alarms,
Faults, Isolates and Other off-normal conditions. Note that the totals take a few seconds to
adjust when the number of off-normal states increases or decreases.
To determine the source of the fault conditions, use the following keypad commands:
Zone Status Searches command for zone faults
(refer Section 7.6.3)
Recall System Faults command
(refer Section 6.6)
Recall History command
(refer Section 6.8)
Point Status Searches command
(refer Section 8.1.5)
Note that the Recall Zone Searches will show all zones that have faults, regardless of the
Isolate status of the zone. The Recall History command can help to determine the sequence
of fault conditions as the events are ordered chronologically.
Once the source of the fault has been determined, apply the basic trouble-shooting
guidelines described in Chapter 10, then call your maintenance company.
NOTES:
(a)
Subsequent faults on the system will operate the fault sounder again.
(b)
RECORD ALL EVENTS IN THE LOG BOOK PROVIDED.
