How to Fix It

  1. Identify the faulted zone number

  2. Inspect the sensor on that zone

  3. Check the battery in wireless sensors

  4. Check wired sensor connections

  5. Bypass the faulted zone temporarily

  6. Check the zone fault code details on the keypad

Frequently Asked Questions

Honeywell Home alarm shows zone fault even when all doors are closed — why?

A zone fault with closed doors usually means a wireless sensor has a dead battery, or a wired sensor has a broken loop wire. Check the battery first in wireless sensors.

Honeywell Home alarm zone fault cannot be cleared — how to reset?

If the fault remains after fixing the sensor, enter your user code to reset the fault acknowledgement: user code + Off key. If the fault persists after resetting, the sensor or wiring still has an issue.

Honeywell Home alarm zone fault on a zone that has no sensor installed — cause?

An unused zone programmed as active in the panel will show a fault if no sensor is connected. The zone should be programmed as Not Used in the system programming. Contact your alarm installer to update the zone configuration.
