Fault codes by panel

Yellow General Fault indicator on the XFP: the manual says it flashes yellow when there is a fault condition on the panel, and will always be lit in conjunction with at least one other fault LED.

Yellow Power Supply Fault indicator on the XFP: the manual says it is lit yellow when the panel's power supply or mains has failed, or the panel's standby battery is in poor condition.

Amber System Fault indicator on the XFP: the manual says it is lit amber when a system error, such as a microprocessor fault, occurs, and it remains lit even if the panel automatically clears the fault.

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…

The XFP earth-fault monitoring has detected an abnormal connection between the fire system and earth.

The XFP power-supply monitoring indicates a supply, battery or earth-monitoring problem.

Sounder Status indicator on the XFP: the manual says it flashes yellow when a fault is detected on either of the panel's two conventional sounder circuits, or if there is a sounder disablement anywhere on the system.

Per the manual, this function monitors one addressable point under intensive, repeated polls from the panel, and reports how many good and bad polls occur between the panel and the device, which can help pinpoint loop…

Per the manual, this engineering function momentarily asserts the LED outputs of loop devices in one continual sweep, and is useful for locating open or short circuit faults on the loop wiring. LEDs are asserted step by…
