Troubleshooting
12
The FP-08451 Control Panel provides a comprehensive fault monitoring system that will detect
any open-circuit in the Circuit 1 Alarm Output, Circuit 2 Alarm Output, Siren/Strobe Output,
Discharge Output and Agent Released Input and any malfunctions of the control panel's internal
components.
When in a fault condition, the control panel will operate the "Fault" LED indicator and operate
the internal sounder. The control panel uses a coded sequence to indicate the type circuit to
the operator. Note: To diagnose if a fault is internal or external, attempt to isolate the panel.
If the control panel can be isolated, the fault is external. (see 9.2 Isolating the Control Panel).
Fault Indicators
12.1
A fault will be indicated if any monitored circuit connected to the panel is not complete. This
could be caused by the devices connected or the wiring to each device. This will display as:
Internal Sounder
1 beep
2 beeps
3 beeps
4 beeps
This will require inspection and testing of connections and installed components. End-of-line
plugs should be plugged directly into the panel, to return it normal condition, and then used to
systematically check along the effected circuit(s). If the fault persists, contact your supplier.
Panel is Unresponsive
12.2
If the panel has become unresponsive, check the incoming power supply. Panel will operate
down to approx. 9vDC. If incoming voltage is above this contact supplier.
Internal Faults
12.3
An internal fault cannot be isolated and will display as:
Internal Sounder
Continuous, steady beep
Continuous, pulsing beep
Internal faults can be rectified by powering down the panel and powering up again. This will
reset the system to normal conditions. If the fault persists, contact your supplier.
Agent Released Fault
12.4
Refer to 3.2 Agent Released Input. If the Agent Released LED is illuminated, this indicates a
fault on the Agent Release input. Typical causes are that the thermal fuse coupling has
operated or has been disconnected. To test if the thermal fuse coupling has operated, check
with a multi-meter for a closed circuit. Thermal Fuse couplings are single use only. If the
thermal fuse coupling has operated, it must be replaced (P/N FP-08825). If the thermal fuse
coupling is functioning normally and the fault persists, contact your supplier.
