Fire-Lite MS-9600: GROUND FAULT

Fire-Lite MS-9600·0 views·0 field notes

What This Code Means

This condition indicates a ground fault, specifically zero impedance between the Fire Alarm Control Panel (FACP) and ground.

Common Causes

  • 1Zero impedance between FACP and ground
  • 2Conduit alone used for earth ground without a solid building earth connection
  • 3Improper wire type, gauge, or run length for system circuits

Resolution Steps

Attach solid earth ground wire to grounding stud. Connect ground wire from Earth Ground terminal to a solid building earth, as conduit alone will not provide a reliable earth ground. Disconnect all sources of power before servicing and verify that wire sizes are adequate for all initiating and indicating device loops.
