Possible causes and solutions:
Ground Fault Detect enabled
The control panel has a ground fault detection circuit that when enabled, detects ground faults on Terminals 1 to 9 and 11 to 30. If a ground fault condition occurs, the keypads annunciate a ground fault and control panel transmits a trouble message.
Ground Fault condition is corrected
When the control panel recognizes that the ground fault condition is corrected, and remains corrected for between 5 to 45 consecutive seconds, the control panel clears the fault from the keypad display and sends a restoral report
Measure earth ground (Terminal 10) and COMMON (Terminal 9) to determine whether the control panel has the necessary 0 VDC decay to -2.1 VDC. Measuring and comparing voltage for ground fault detection:
Set your digital voltmeter (DVM) to measure VDC.
Connect the red DVM lead to control panel Terminal 10, and the black DVM lead to Terminal 9.
Compare this voltage to the following table:
Enable Ground Fault Detect and reports
To enable fault detection, use RPS. Set the following parameters:
· PANEL WIDE PARAMETERS > Miscellaneous > Ground Fault Detection. Set to Enable
· PANEL WIDE PARAMETERS > Report Routing > Burglar Reports > Trouble Report. Set to Yes.
· PANEL WIDE PARAMETERS > Report Routing > Burglar Reports > Burg Restore (After Trouble). Set to Yes.
