11. GENERAL FAULT FINDING
11.1 COMMON FAULT.
This is a general indicator which lights whenever a fault is present. It doesn't refer to a
specific fault.
11.2 ZONE FAULTS
There are several reasons for the zone fault LED to light.
1. There is a break, or short circuit to devices in that zone,
2. A device has been removed from that zone
3. A device in that zone is communicating a fault condition to the panel with its analogue value. A
value less than 8 is usually a fault condition. (This could be a zone monitor reporting a fault in its
external PSU for example.)
The LCD screen should give further information about the
fault. It may give the loop, address & label of the device
causing a problem. If it reports a loop fault, then this indicates
a break (or short) in the loop cable. (note that if Spurs
are used, the panel may not detect the brake, but will still
report the device missing)
Entering the device status menu & viewing the address
which shows a fault will also help identify the problem.
If the device is present, but gives a fault value (less than 8),
then there is a problem with that device or one of its add on
components (eg power supply)
If the device is missing (NONE*), then :-
Check the device has not been removed
Check that there is power to the base
Check that its address hasn't been changed (compare to system set-up chart)
Check that the base contacts are clean and free from dirt & corrosion
If possible, try a replacement head (remembering to set the correct address)
11.3 SUPPLY FAULTS
a. BATTERY FAULT
Loss of Battery power – Remedy
i.
ii.
b. CHARGER FAULT
Loss of Mains power – Remedy
i.
ii.
iii.
c. LOW BATTERY
Low Battery voltage detected – Remedy
i.
ii.
iii.
Other possible causes of supply faults are:-
Wrong Charging Voltage.
The charging voltage should be 28.3V off load at 22-24
potentiometer VR1
Overcharged Batteries.
Remove the batteries and measure the voltage. If it is reading over 27.4 then the batteries
are overcharged. Try to run the panel on batteries only for half an hour or so to try to
discharge the batteries. If this doesn't solve the problem, replacement batteries will be
required.

Check battery fuse FS2.
Check that battery connections are secure.
Check mains fuse (Conn 6).
Check that main power is present.
Check charger fuse FS1.
Check battery voltage. (should be around 26-27V)
Check that 2 x 12v batteries are connected in SERIES) to give 24V
Check that charger fuse FS1 is ok
