Fire-Lite MS-5024: Ground fault

Fire-Lite MS-5024·1 view·0 field notes

What This Code Means

The control panel has detected a ground fault condition on the supervised field wiring or initiating device circuits.

Common Causes

  • 1Field wiring contact with ground
  • 2Improper Earth Ground connection to the grounding stud
  • 3Use of conduit for the Earth Ground connection
  • 4Lightning induced transients

Resolution Steps

Check all field wiring for ground faults. Connect the Earth Ground wire (minimum 14 AWG) to the grounding stud indicated by the ground symbol label. Do not use conduit for the Earth Ground connection since this does not provide reliable protection. Verify that wire sizes are adequate for all initiating and indicating device loops.
