Fault codes by panel

Per the manual, if the system faces a loop -ve open circuit during initialisation, initialisation continues to the end of the loop and all devices are operational (as long as no other faults exist). A message of…

Per the manual, after initialising the loop, if the number of devices initialised does not match the number programmed, a DEVICE QUANTITY MISMATCH screen appears showing the number found and programmed. A mismatch…

Per the manual, if no obvious causes are apparent, replace the device. It also notes that a short circuit between cores with a value between 3 k and 300 ohms can corrupt data on the loop even though no short circuit…

Per the manual, if the panel detects a short circuit to earth/screen from one of its supply rails (0 V or +ve) an Earth Fault is displayed. Remove the circuit cables one at a time and reset the system: when the faulty…

Yellow EARTH FAULT indicator, flashing: the manual says an earth fault has been detected where a path exists from the circuit wiring to earth; remove circuits one at a time to discover which one, and then rectify. An…

Yellow FIRE OUTPUT indicator, flashing: the manual says a fault condition is present on a monitored relay circuit or on the addressable device loop outputs. Continuous means a device or action associated with the…

Yellow LOOP indicator, flashing: the manual says a fault condition is present on one or more addressable device loops, or one or more addressable devices. Continuous means a device or an action associated with the…

Per the manual, if random or recurrent loop open circuit faults are reported, check the entire system for: loose connections; broken connectors (over-tightening can break the connector body and cause an intermittent…

Per the manual, if short circuit or open circuit faults occur on the loop wiring the panel detects them and indicates them with the yellow loop fault LED and logs them in the event logs. Adjacent devices open their…

Yellow POWER FAULT indicator, continuous: the manual says a battery supply or charger fault has been detected, and to check the fuse and the battery voltages.

Yellow POWER FAULT indicator, flashing: the manual says the mains supply has failed, and to check the fuse and the 230 V AC supply on the PCB AC terminals.

Per the manual: make sure the correct device is being investigated by comparing its description with the device address and/or serial number; make sure the optical chamber is clean, and if not replace it with a new one…

Yellow SOUNDER indicator, flashing: the manual says a fault condition is present on a monitored sounder circuit or on the addressable device loop sounders. Continuous means a device or action associated with the…

Yellow SYSTEM FAULT indicator, flashing: the manual says it indicates the presence of a processor or a checksum error. Power the system down to clear, reprogram all settings and test the system.
