LPCB APPROVED CFP ALARMSENSE 2/4/8 ZONE FIRE ALARM PANEL

1.4 Repeater faults

•
To find out which of the repeater panels are faulty:
1. Remove the panel's lid using the Torx key provided and press the ACCESS LEVEL THREE FUNCTIONS
button on the Main Control PCB to gain access to the panel's engineer functions (see below).

2. Continue pressing the ACCESS LEVEL THREE FUNCTIONS button until the REPEATER FAULT light pulses.
Any existing Zone Fault lights are suppressed and the zone light(s) corresponding to the repeaters in
fault are illuminated, e.g. if repeaters 2 and 7 are faulty, the Fault Lights for zones 2 and 7 will be lit.
To exit access level 3, press the ESCAPE ACCESS button at any time.
Suggested action: Refer to the Repeater Panel Instructions for repeater fault-finding advice.

1.5 Conventional sounder faults

•
To determine which of the panel's four conventional sounder circuits are faulty:
1. Disconnect each sounder circuit from the Main Control PCB in turn and measure the resistance between
the two wires. A good circuit will present only the end-of-line resistor value. Any other resistance value
shows a fault.
2. If the readings from all sounder circuits are correct, take their end-of-line resistors and connect them to
the sounder circuits at the panel without the sounder circuit wiring. If the fault still persists, the panel is
faulty and must be replaced.
3. If a sounder circuit fault is detected, correct the fault and reconnect the sounder circuit. The sounder
fault will automatically clear within 60 seconds.
Note: If the sounder circuit is shorted and the alarm voltage applied, the relevant sounder fuse will trip. When
the fault is removed, the fuse will automatically reset.

1.6 Remote output faults

If the panel's 24V auxiliary output (which is typically used to supply relays switched by the remote output) is
subject to current overload, its protection fuse will trip. This will result in the remote fire output showing a
fault condition by flashing its respective light.
Repairing the fault will reset the fuse and clear the associated Fault light.

MAINTENANCE

Periodic system maintenance should be carried out on the system as prescribed in the local design, maintenance
and installation regulations.
The Fire Alarm panel's standby batteries should be checked for integrity of the connections, deposits indicating
venting, and a periodic load test with the Mains supply disabled to ensure adequate battery capacity. Both
batteries should be renewed if there is any doubt about their integrity.
