Fault codes by panel

Shown against the specific loop address, zone and location text on the display, e.g. "1 004.0 DEVICE MISSING" under the zone's fault list. Indicates the panel is no longer receiving a response from that addressed device.

The device does not respond (lost or damaged).

The device is not responding (the device is lost or failed).

Per the manual, power is driven from the LOOP OUT terminals and returned to the LOOP IN terminals, where it is monitored for loop continuity. If the loop is open circuit (a cable fault, or a short circuit isolator…

The operation guide uses NO ANSWER for a stored loop device that is not responding and provides a controlled same-type replacement workflow.

Per the manual, a fault is indicated if any part of the system enters an abnormal condition. The COMMON FAULT LED pulses (and the ALARM FAULT/DISABLEMENT LED also pulses if the fault is with an alarm circuit), the…

Loop PCB missing or failed to respond. Possible causes are: a. Wrong ribbon cable connected; b. Ribbon cable disconnected; c. Loop PCB failure. Action: For the last case, change the loop PCB (PN: 020-588).

Parameterised message covering sounder circuits 1-4 (X = 1, 2, 3 or 4), as printed in the source. Indicates an open circuit (disconnection condition) fault on the sounder circuit wiring. Action: For circuits 3 and 4,…

Parameterised message covering sounder circuits 1-4 (X = 1, 2, 3 or 4), as printed in the source. Indicates a short circuit fault on the corresponding sounder circuit wiring. Action: For circuits 3 and 4, check that the…

This fault indicates that the peripheral unit connected to the third-party-protocol RS232 port has not responded to the enquiry code sent, or the link to the third-party equipment is not connected (this would normally…

The yellow Earth Fault LED indicates an earth isolation fault. Earth fault reporting can be switched off under Panel setup > Other settings > Fault notification ("Earth", available on fire alarm control panels and…

A repeater on the RS485 does not respond

Displayed for each swapped C-NET device if the C-NET detector line was restarted after devices of the same type were swapped over in their bases. To clear, at least the device types in the corresponding bases must be…

Per the manual, when a fault occurs one or more Fault indicators flash yellow, the internal buzzer sounds (if enabled) and the fault button on the touchscreen changes from blue to yellow with the number of faults shown.…

Per the user manual, if part of the fire alarm system fails (for example detector failure or a wiring fault), one or more of the panel's fault indicators flash, the internal sounder (if enabled) pulses, and the display…

Per the manual, if the system faces a loop +ve to -ve short circuit or a loop +ve open circuit during initialisation, initialisation fails at that point and a message of Loop not complete is displayed. Devices up to…

Message shown on the ID50/ID60 panel. The manual's Appendix 3 gives the meaning as: During automatic testing of loop devices a specific device did not respond as expected. Action listed in the manual: Change device.

Message shown on the ID50/ID60 panel. The manual's Appendix 3 gives the meaning as: Two loop addresses are responding to the same address. Action listed in the manual: Change one of the two devices to a different…

Message shown on the ID50/ID60 panel. The manual's Appendix 3 gives the meaning as: A loop device at a specific address is not responding, possibly missing or incorrect panel configuration. Action listed in the manual:…

The manual says most faults need checking by an engineer, but the system can be checked for a removed detector by the responsible person. All faults in the Premier Elite are non-latching: they cannot be reset with the…

LCD event text on the Zeta Premier AL. The manual's Appendix D describes it as: Removed: the loop device is not responding.

The power supply specification lists the battery high impedance fault (Batt Hi Z) as resistance above 1 ohm, with a 1-hour reporting time.

When the panel detects a fault the display indicates the number and nature of the fault(s), the internal buzzer sounds an intermittent tone and the amber General Fault LED pulses, with any other specific Fault LEDs lit.…

If a fault occurs on a transmission path (short circuit or interruption), the manual says the function of the remaining operational devices is re-established within 300 seconds of the fault, compliant with EN 54-2…

The Power Supply Fault LED pulsing indicates a power supply fault on the mains power input or battery. Steady indicates the same fault with the buzzer muted.

If the mains is connected before the batteries, the panel shows a Power Supply Fault for up to 1 minute until the monitoring cycle has finished polling. The manual says this is normal, and to check connections if the…

The Sounder Status LED pulsing indicates a fault on one or more sounder circuits. The same LED steady indicates sounder circuits have been disabled or are in test mode.

The System Fault LED steady indicates a system failure, that the panel is not functional, or that the internal PCB configuration has not been set up correctly. Pulsing indicates the panel has recovered from a system…

System Fault LED pulsing, General Fault LED pulsing and a pulsed (fault tone) buzzer indicate a system fault has occurred and the affected board has recovered. The indication remains until the panel is reset.

A system fault is a processor watchdog time-out or processor failure. With only the System Fault LED lit and a continuous buzzer, the display board (main control board) is halted and no other indication or control is…
