9. GENERAL FAULT FINDING
9.1 ZONE FAULTS
To assist in fault finding, the infinity panel will display zone faults as follows.
The general fault LED will flash if a fault is present. On the first flash, any zones showing O/C will flash. The second time the General
fault LED flashes, any zones with a Short Circuit fault will flash in conjunction with the General S/C LED. The cycle then repeats,
showing O/C & S/C faults on alternate flashes.
(The internal fault buzzer will also sound, and the fault relay will operate)
The Zone Faults are non-latching faults. That is, if the fault disappears, the panel will automatically reset itself.
Suggested Action
a)
Disconnect the wiring for the zone showing fault, and refit the end of line diode at that zone terminal in the panel. (Stripe to Zone
+ve) If the fault condition for that zone clears, this confirms there is a wiring fault.
b)
Double-check the wiring and the end of line diode on the zone. Trace the fault with consideration for the type of fault
indicated.(HINT: splitting the cable half way down the zone, and fitting the end of line diode to the new end point helps to
determine which section of cable is giving the fault)
Note: A possible fault is a detector head badly seated in a base that is not making the connection.
c)
A short circuit on a zone could be caused by the end of line diode being fitted backwards.
d)
Check that the detectors are compatible with this FACP. Note that some makes of detector will require a series resistor or diode
to be fitted to work properly. There is usually a spare connector on the base to accommodate this (check instructions that came
with the detector).
9.2 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
To reset a system fault, enter the access code, and press reset. If the system fault does not clear, the panel has been damaged, and
will need to be repaired or replaced.
9.3 SUPPLY FAULTS
The Infinity panel indicates supply faults with one long flash, followed by a number of shorter flashes. The number of short flashes
indicates the type of fault:-
1 FLASH
Mains Fault or Cage Fault
2 FLASHES
Battery not present
3 FLASHES
Battery voltage too low
4 FLASHES
Battery internal resistance too high
5 FLASHES
Charger fault
1 Flash - Mains Fault or Cage fault
a.
Check that main power is present.
b.
Check that cage voltage is set to 30.5 V DC
2 Flashes - Battery not present
a.
Check that 2 x 12V SLA batteries are fitted
b.
Check battery fuse FS6.
c.
Check that battery connections are secure.
3 Flashes - Battery voltage too low.
