6. THE FAULT CONDITION

6.1 DIFFERENT TYPES OF FAULT

The fire alarm monitors itself, and any equipment connected to it, for any faults that can occur. If a fault occurs, the Panel
responds by activating its Internal buzzer and lighting the General Fault light and any other Fault light(s) relevant to the
particular fault. The panel will also display the fault on its LCD display. The Panel's Fault relay will also activate. Typical
faults are described below: -
Zone Fault
The relevant Zone Fault light flashes when there is a wiring problem on a Zone or detector has been removed from
its base. It should be noted that any alarms raised on the fault zone(s) may not be recognised by the Fire Alarm Panel
until the Fault Conditions have been cleared. It can take up to10 seconds from repairing a fault for the display to clear.
Power Supply Fault
The Premier AD has 3 separate LEDs to help pinpoint the source of the problem. Battery Fault indicates that there is no
battery connected to the panel. Charger Fault indicates there is a problem with the mains supply (or one of its fuses). Low
Battery indicates that the battery voltage has dropped below 21 volts, and that these batteries are no longer working.
If the mains supply fails, the panel will only operate for the standby period dictated by the size of the batteries fitted. If
the batteries or charger fails at the same time as the Mains, the Panel will be inoperative.
System Fault
The System Fault LED lights when the Panel's micro-processor has Reset, typically after excessive electrical interference,
or if the contents of its memory have been corrupted. This fault can only be cleared by turning the key switch from off
position to control enable position and then back to the off position again. If the fault re-occurs within 1 hour, this is
indicative of a corrupt memory and expert advice should be sought.
Note that leaving the memory write enable switch on also lights system fault as a warning to turn the switch off.

*Due to the nature of a System Fault (CPU not
running correctly), the exact contents of the
display can not be determined. It could be blank,
filled with squares, garbled, or even say system
normal if the CPU has re-started correctly.
