Carbon Monoxide Detector False Alarms

  • updated 1 mth ago

It is important to regularly test and maintain all system sensors. A low battery or abnormal damage to the sensor can cause irregular activity. 

Troubleshooting False Alarms

  1. Make sure the detector is a Cove sensor and not a pre-existing Carbon Monoxide detector
  2. Make sure the sensor was not installed in any of the following places:
    • Directly above a sink
    • Directly above a stove or within 5 feet of any cooking appliance
    • Next to a door or window that would be affected by drafts, like an extractor fan or air vent  
    • Where airflow would be obstructed by curtains or furniture
    • Where dirt or dust could collect and block the sensor
    • Where the sensor could be knocked, damaged, or accidentally removed
  3. Verify the sensor has not expired (a sticker on the outside of the device has an expiration date)
  4. Replace the battery (CR123A)
