Fault codes by panel

Listed in the fault-message table on the row after System Fault (LED 5), with no LED number of its own. Action: Restart the 'Station'; when the fault is still indicated, exchange the module.

Panel fault text shown on the DX display. The manual's example shows it as an input open circuit on 'Monitored Input 1' registered at 12:15, as one of three panel-related faults. The manual gives it only as an example…

In fault diagnosis mode (press and hold ENTER), a Zone 1 to 6 Fire LED that is steady after pressing ENTER indicates an open circuit on the matching sounder circuit (Zone 1 and 2 = Main PCB SNDR 1 and 2; Zones 3 to 6 =…

Per the manual, a continuous System Fault LED with the General Fault LED pulsing and a continuous buzzer means the main board, or the extender card if fitted, is halted. The fault relay is activated, and alarms may be…

For zones 1 to 4 on the Main PCB, in fault diagnosis mode (press and hold ENTER) the Zone Fault/Disabled/Test LED steady after pressing ENTER means that zone has an open circuit.

In fault diagnosis mode (press and hold ENTER), a Zone 1 or Zone 2 Fire LED steady after pressing ENTER indicates an open circuit on sounder circuit 1 or 2 (Main PCB SNDR 1 and SNDR 2). The LED going off after pressing…

For zones 1 to 4 on the Main PCB, in fault diagnosis mode (press and hold ENTER) the Zone Fault/Disabled/Test LED steady after pressing ENTER means that zone has an open circuit.

Flashes yellow when there is a fault on any part of the fire alarm system. It is always lit together with at least one other Fault light that shows the precise type of fault detected.

If the green Supply Present light is not lit, either both the mains supply and standby batteries have failed, or the Power Supply PCB, the Main Control PCB, or the cable connecting them is faulty.

If the green Supply Present light is not lit, either both the mains supply and standby batteries have failed, or the Power Supply PCB, the Main Control PCB, or the cable connecting them is faulty.

Lit whenever any fault condition exists on the panel. One documented specific cause: if the buzzer sounds and the General Fault light is lit steadily with no other cause found, the panel has been left in a test mode —…

This indicates that a device has been installed without setting a valid address, i.e. left at factory default of '00'. No separate remedial action is stated beyond this cause in the source.

No separate cause description is given beyond the message name. Action: For IPX sensors, replace with SDX751TEM or equivalent. For other MULTI and SMART sensors, replace (sensor is faulty).

For VIEW, MULTI (Optiplex), or SMART sensors: the analogue reading is below the Chamber fault threshold, or below the Maintenance Urgent threshold, or a Maintenance Alert has existed for longer than 100 days without any…

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,…

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…

From the panel's own "View - Panel" diagnostic table: each loop's load is monitored 0mA-500mA; the panel reports Open Circuit when the reading falls outside that range in the open direction. Loop Load, V.Out and V.In…

From the panel's own "View - Panel" diagnostic table: Sounder A/B is monitored 0V-14V, normal 5.5V; the panel reports Open Circuit when the reading falls outside that range in the open direction.

The loop current reading indicates an open-circuit state on the detection loop. From the official Advanced MxPro5 User Manual's Local Hardware diagnostic table (section 3.9.7.2, pp.22–23), which lists Open Circuit as…

A supervised sounder output circuit (Sounder A/B, and C/D on the 5400) reads open circuit. From the official Advanced MxPro5 User Manual's Local Hardware diagnostic table (section 3.9.7.2, pp.22–23), which lists this as…

If a control panel previously configured to be in the fire network is not detected, a fault message indicating the offline status (with the Firenet ID) is reported. From the ZP2 Series Installation Manual, "Firenet…

There is a short circuit fault in the network between CH1+ and the screen. Not available on some panel options.

There is a short circuit fault in the network between CH1- and the screen. Not available on some panel options.

Message shown on the Vigilon panel. Meaning per the manual: the device indicated is not functioning correctly. Indications listed: Fault. Action listed in the manual: the device needs replacing.

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…

Circuit broken at input 'Alarm Confirmation'.

Event message on the SIMPO addressable panel. The manual's Appendix A table describes it as: Circuit broken at Extinguishing output. The manual gives no cause or action for this message.

Event message on the SIMPO addressable panel. The manual's Appendix A table describes it as: Circuit broken at Fault output. The manual gives no cause or action for this message.
