Preventing False Alarms From the Smoke & Carbon Monoxide Detector


Our Smoke & CO Detector uses photoelectric sensors, meaning it detects smoke through the distortion of a light beam inside the detector. Photoelectric smoke detectors will detect smoke faster than other detector types but can occasionally result in a false alarm. False alarms often occur when the device detects other particles in the air. Common false alarms are typically due to excess steam from a bathroom or kitchen, dust build-up inside the sensor, or (rarely) a tiny bug finding its way inside. 

You can prevent false alarms by cleaning the device once a month:

  1. Make sure to remove the battery before cleaning

  2. Open the cover and vacuum the dust off the sensing chamber at least once a month

  3. Replace the battery after cleaning

  4. Test the smoke detector to make sure the battery is working correctly

Vacuuming the device monthly should prevent dust or debris build-up, and is an especially good idea after you have experienced a false alarm. Also, make sure to install the Smoke & CO Detector away from anything that will produce steam. 

If there is a false alarm triggered by steam, dust, or debris, the primary contact will receive an alarm text prior to being called. The alarm text will notify you of the alarm at your location, but cannot be used to cancel the alarm or the request for emergency services. The primary contact who receives a phone call can cancel the alarm event over the phone by providing the agent with your safe word. If you do not answer the phone call, we will place a call to your local fire department to request assistance at the location of your system.

If the Smoke & Carbon Monoxide (CO) detector detects CO, three things will happen at once. You will receive an alarm text, you will be called, and emergency services will be requested at your location. There is not a way to cancel the request for dispatch of emergency services when a CO detector is triggered, as Carbon Monoxide poisoning is a serious, and potentially life-threatening occurrence.
