Fault records by panel

Yellow LED indicator. Indicates that there is a fault condition in the Fire Brigade signalling equipment. From the official Advanced MxPro5 User Manual (LED Status Indicators table, section 2.2). This is the User…

Yellow LED indicator. Indicates the presence of a fault in one or more sounder wiring circuits. From the official Advanced MxPro5 User Manual (LED Status Indicators table, section 2.2). This is the User Manual, not the…

Yellow LED indicator. Indicates the presence of a system fault. From the official Advanced MxPro5 User Manual (LED Status Indicators table, section 2.2). This is the User Manual, not the fuller Installation and…

The panel's internal earth-monitoring circuit reads outside its normal band, typically indicating cable insulation breakdown or earth leakage. From the official Advanced MxPro5 User Manual's Local Hardware diagnostic…

Applies only when the Routing Interface is set to Monitored (Section 3.3.15.8). Function LED3 (Yellow) indicates a fault in the transmission path of the fire routing connection, and also illuminates if there is a fault…

A monitored output circuit (sounder, bell, relay output) has reported an open or short circuit. The panel monitors these circuits with an end-of-line (EOL) device.

Raised against an analogue loop device once its measured compensation-drift value exceeds a preset limit — typically dust or contamination affecting a detector's chamber over time. Preceded by a non-fault "Warning"…

The panel display shows the affected zone and device text with "DEVICE MISSING" alongside the device type (e.g. "(MULTI.SENSOR)"), from a worked example in the official Advanced MxPro5 User Manual (section 3.3, Fault…

The panel raises this fault once the programmed "next service due" date is reached, alerting the site operator that a maintenance visit is overdue. It clears automatically once a new service date is entered. From the…

The loop current reading indicates an open-circuit state — a break, loose terminal or removed device on the detection loop. All devices beyond the break will be reported as missing; short circuit isolators (SCIs), if…

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.

From the panel's own "View - Panel" diagnostic table: Earth Monitor is monitored 0V-30V, normal 1.3V; the panel reports Too High when the reading exceeds the expected range. Whether Earth Fault is shown on the display…

Loss of incoming AC mains. The green Power LED flashes immediately; the fault condition itself can be configured with a reporting delay (Address 14.0, "AC Fail Delay") before the panel raises it as a fault. From the…
