What to do if Honeywell Silent Knight SK318PT panel indicates a ground fault?
- M
  Misty SmithAug 12, 2025
  If your Honeywell Fire Alarm panel displays a “GROUND FAULT” message, it means the panel detects an unexpected current flow from one or more terminals to the earth connection. To fix this, isolate the wiring causing the fault by removing connections one at a time, pausing at least five seconds between each removal, until the fault clears. Note that connecting a computer to the panel via a serial cable can also trigger this message, which can be ignored and will clear upon disconnection.

Why Honeywell Silent Knight SK318PT Fire Alarms SLC devices are not being recognized?
- A

  If your Honeywell Fire Alarms system displays a “Missing” message for SLC devices, check the hardware connections to ensure they are correctly wired. For the main panel, the positive side of the device should connect to terminal 34, and the negative side to terminal 33. For 5815XL devices, ensure they connect via the SLC OUT terminals. There should only be one SLC loop on the main panel and each 5815XL module, and devices should not be connected to terminals labeled SLC IN. Also, verify that the SLC devices have been properly addressed. For contact monitor modules using DIP switches, the switch must be set to the correct address before power is applied, or the device will have an incorrect address. Finally, ensure correct polarity has been observed for SLC device wiring.

How to fix Honeywell Silent Knight SK318PT Fire Alarms if 5815XL module is not being recognized?

  If a 5815XL module is not being recognized by your Honeywell Fire Alarms panel, check the 5815XL green LED. If it flashes on and off every half-second, the module likely needs to be added to the system through programming. Ensure the correct ID for the 5815XL module has been set using the DIP switches (ID#1 for the first module, ID#2 for the second). Also, verify the wiring between the 5815XL and the panel, measuring the voltage from the 5815XL Terminal (+) to Terminal (-); it should be between 27.2-27.4V when AC power is present. If the green LED isn't flashing, the wiring between the 5815XL and the panel is likely incorrect.

  If a 6815 module is not being recognized by your Honeywell Fire Alarms panel, check the status of the 6815 green LED. If the LED flashes on and off every half-second, the 6815 likely needs to be added to the system through programming. Verify that the correct ID for the 6815 module has been set using the DIP switches (ID#1 for the first 6815, ID#2 for the second). Ensure the wiring between the 6815 and the panel is correct, and measure the voltage from 6815 Terminal (+) to Terminal (-); it should be between 27.2-27.4V when AC power is present. If the green LED is not flashing, the wiring between the 6815 and the panel is likely incorrect.
