Earth Fault
An EARTH fault indicates that something is shorting to earth (usually through the cable screen).
Disconnect the earth screens one at a time to determine the problem line.
(Note: connecting other equipment , eg an oscilloscope or PC, to the panel can give an earth fault)
The voltage between battery –Ve and earth should be 14-16 volts. If it is not, the voltage should
indicate what is shorting to earth.
System Fault
A system fault is an abnormal microprocessor running condition due to various unexpected
phenomena.
This will result in the panel attempting to correct itself. Should this fault occur, the System Fault LED,
General Fault LED, General Fault relay and fault internal buzzer will be constantly active until the
control keyswitch is turned from off position to control enable position. This should cause this fault
condition to reset. If not, consult your supplier.
Repeater fault
The panel can no longer communicate with the repeater (check that the cables are intact, and that the
fuse in the repeater, and the panel`s serial supply line are intact. If the system does not have a
repeater, then the monitoring link has been incorrectly fitted.
Remote Fault
The panel has received a signal on it`s remote fault input. Check any items connected to this input.
