Fault records by panel

The earth fault monitor detects the presence of an earth on the positive or negative sides of the system. Should this condition occur, disconnect the field circuit wiring one cable at a time and view the LED at the top…

The yellow Earth Fault LED indicates an earth isolation fault. Earth fault reporting can be switched off under Panel setup > Other settings > Fault notification ("Earth", available on fire alarm control panels and…

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…

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.

Something is shorting to earth on the negative side. Located using the same method as an Earth Positive Fault, but looking for shorts to loop negative rather than positive.

Something is shorting to earth on the positive side (usually through a cable screen). Most earth faults occur on the addressable loop — disconnect all loop connections and reset the panel; if no earth fault is reported…

The ZFP earth-fault monitoring circuitry has detected an abnormal system connection to earth.

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

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…

Per the manual, if the panel detects a short circuit or leakage current to earth/screen from one of its supply rails (0 V or +Ve) an Earth Fault is displayed. The normal voltage between 0 V and Earth SCRN is 1.7 V; the…

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…

Message shown on the ID50/ID60 panel. The manual's Appendix 3 gives the meaning as: A wiring fault has been detected to earth. Action listed in the manual: The fault can be narrowed down by systematically disconnecting…

Per the manual, an earth fault indicates that something is shorting to earth, usually through the cable screen. Disconnect the earth screens one at a time to determine the problem line. Connecting other equipment, for…

Diagnostic LED 18 on the ZP3 power supply/main board: the legend lists it as default off, and green on means an earth fault.

The panel's internal earth-monitoring circuit (Earth Volts) reads outside its normal band. From the official Advanced MxPro5 User Manual's Local Hardware diagnostic table (section 3.9.7.2, pp.22–23), which lists Too…

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

The CIE-A-400 has detected a short or leakage path between earth or screen and either 0 V or a positive circuit conductor.

When this indicator is on, there is leakage current flowing between the earth connection/wiring and any other wire connected to the panel.

The xDetect panel has detected an unintended connection from a panel input or output to earth.

The xDetect Mini panel has detected an unintended connection from a panel input or output to earth.

Resistive connection between some signals and earth, below 10kΩ.

Power supply status indicator on the Zeta Premier AL power supply board. The manual lists it as: Earth fault, printed in the manual as “Earth fault (disabled)”; the diagram beside it shows the earth fault monitoring…

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

Data returned from a loop device is being corrupted over a period of time. Action - Check: a. The continuity of loop screens; b. The screen is connected to earth at one point only (normally at the panel). Note: the…
