Fault codes by panel

Per the manual, the control panel can detect devices that have been set to the same address and will announce a “Double address” fault if it finds any. It cannot tell which devices are double addressed. To help find…

This message is one of ten Processor Fault messages the source groups together under a single shared action: if any of these faults occur repeatedly and randomly, replace the CPU PCB assembly (PN: 020-569). No separate…

Yellow POWER FAULT indicator, flashing: the manual says a mains supply fault has been detected, and to check for a 230 V AC supply on the incoming AC terminals.

Yellow SYSTEM FAULT indicator, flashing: the manual says this LED is also illuminated if the write protect / write enable switch is left on while the system is not in the engineer menu. In access levels 1 and 2 a system…

Per the manual's LED table, a flashing yellow Fault indicator means there is a fault condition on the system. See section 5.3 for details.

Per the manual, a flashing yellow Sounder Fault indicator means a fault has been detected on the panel's sounder circuits; steady yellow means the panel's sounders have been disabled. Action listed: call the service…

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.

No separate cause description is given for this message beyond its name. Action: Change the Base PCB (PN: 020-568) or Extension Chassis with Display Module Kit (PN: 020-559-XXX).

The network has unexpectedly lost the master panel, so another panel has automatically been assigned as master until the problem is fixed.

There is a memory corruption in the network card; replace the card.

The yellow Fire Protection Fault/Disabled/Test LED indicates a fire protection fault, disablement, or test. A flashing LED indicates a fault; a steady LED indicates a disablement or a test. From the ZP2 Series…

The yellow Sounder Fault/Disabled/Test LED indicates a sounder fault, disablement, or test. A flashing LED indicates a fault; a steady LED indicates a disablement or a test. From the ZP2 Series Installation Manual,…

The sounder fault/disabled indicator lights when any output treated as a sounder is faulty or disabled. Syncro AS treats an output as a sounder when its Silenceable and Evacuate Output attributes are selected. The same…

When a repeater fault is displayed, press and hold ENTER: a slow flash of the Repeater Fault LED indicates a faulty repeater. Red fire LEDs 1 to 8 show which repeater was offline, and amber fault LEDs 1 to 8 show which…

When a repeater fault is displayed, press and hold ENTER: a fast flash of the Repeater Fault LED indicates a network cable error.

When a repeater fault is displayed, press and hold ENTER: a normal flash of the Repeater Fault LED indicates the repeater is off line. Red fire LEDs 1 to 8 show which repeater was off line.

In the device Fault Status menu, this indicates the device is not yet assigned to the system. Assign it via the rotary control or the Assign Devices menu option.

Occurs as a result of a momentary disturbance in the panel's microprocessor. In access level three fault diagnosis this shows as Zone 3's Fault light lit.

The panel has detected leakage to earth; the manual specifies indication below 30 kOhm from +28 V or 0 V to earth.

Yellow Earth Fault indicator on the ZX series panel: an earth connection fault has occurred on a cable. To clear it, correct the fault condition and then perform a panel reset (page 7). The alphanumeric display shows a…

Front-panel indicator on the ZX series panel. Function per the manual: the panel has detected a fault (yellow indicator). How to clear, per the manual: correct the condition causing the fault and then perform a panel…

Front-panel indicator on the ZX series panel. Function per the manual: the CPU has reset or a system fault has occurred (yellow indicator). How to clear, per the manual: correct the problem, if appropriate, and then…

Front-panel indicator on the ZX series panel. Function per the manual: flashing means the zone contains faulty devices; steady means the zone is either disabled or in test mode (yellow zone indicator). How to clear, per…

The source names this fault message and gives only the applicable module/input numbering (x from 1 to 4); it states no cause, meaning, or remedy beyond that numbering. No cause is asserted here beyond what the source…

Front-panel indicator on the DX Dimension Series panel (yellow). Function per the manual: an earth connection fault has occurred on a cable. How to clear, per the manual: correct the fault condition and then perform a…
