1.1.4 Processor Faults
System Fault 40 - Main CPU Watchdog Operated
System Fault 41 - EPROM Memory Checksum
System Fault 42 - E2PROM Memory Write Error
System Fault 43 - FLASH Memory Checksum
System Fault 45 - FLASH Memory Write Error
System Fault 46 - Software error
Panel Fault 49 - CPU Watchdog timer fault
System Fault 64 - CPU Watchdog not enabled
System Fault 66 - CPU Clock Monitor Failure
System Fault 67 - CPU Illegal Instruction
Action: If any of these faults occur repeatedly and
randomly, replace the CPU PCB assembly (PN: 020-569).
1.1.5 Sounder Faults
Sounder Cct.1 SHORT-CCT.
Sounder Cct.2 SHORT-CCT.
Sounder Cct.3 SHORT-CCT.
Sounder Cct.4 SHORT-CCT.
This fault message indicates a short circuit fault on the
corresponding sounder circuit wiring.
Action: Check that the user-defined links (JP22-JP27) on
the Base PCB are in the correct position (refer to
Section 8.7 Sounders Volt-free Contact Option).
Action: Disconnect the sounder circuit wiring and use a
multi-meter to locate the fault.
Sounder Cct.1 OPEN-CIRCUIT
Sounder Cct.2 OPEN-CIRCUIT
Sounder Cct.3 OPEN-CIRCUIT
Sounder Cct.4 OPEN-CIRCUIT
This fault message indicates an open circuit (disconnection
condition) fault on the sounder circuit wiring.
Action: Check that the fuse (F1 to F4 respectively) on the
Base PCB is intact. Check that the user-defined links
(JP22-JP27) on the Base PCB are in the correct position
(refer to Section 8.7 Sounders Volt-free Contact Option).
Action: Disconnect the wiring and use a meter to locate
the faulty sounder or cable. A 4k7 resistor should be
connected to the end of the cables.
Sounder Cct.1 RELAY FAULT
Sounder Cct.2 RELAY FAULT
Sounder Cct.3 RELAY FAULT
Sounder Cct.4 RELAY FAULT
This fault indicates a failure of the drive relays to the
sounder circuits, and not the attached cables.
Action: Circuits 1 & 2 only: check that the termination is
4k7 and that the SND jumper is at JP2/4/6 (OUT 1) or
JP3/5/7 (OUT 2) respectively. If these are correct, or if the
fault is on circuit 3 or 4, change the Base PCB (PN: 020-
568).
