Smoke and C02 Detector Activation and Chirping

Modified on Mon, 8 Sep at 4:34 PM

If your smoke and C02 detector alerts or chirps it is important to take immediate action to ensure your safety and the safety of others in your home.


Immediate Action

  • Check for signs of smoke or fire; if the alarm is a smoke detector, quickly check for signs of smoke or fire in your home. If you see smoke or flames, evacuate immediately and call 911. 
  • Check for signs of carbon monoxide; if the alarm is a carbon monoxide detector, open windows and doors to ventilate your home, turn off any fuel-burning appliances, and evacuate the home immediately. Call 911 or a qualified technician to check for carbon monoxide levels.
  • Silence the alarm: if you determine that the alarm is a false alarm, such as from burnt toast or cooking fumes, silence the alarm by pressing the "silence" or "hush" button. Do not remove the batteries or disable the alarm unless you are sure there is no danger.
  • Replace the batteries: If the alarm is low on battery, replace the batteries immediately to ensure that it continues to function properly. 
  • Test the alarm: Regularly test the alarm to make sure it is working properly. Refer to the user manual for instructions on how to test the alarm.


Chirping units

Manufacturers provide a product warranty, however the builder is only responsible for the product for one year from your closing date.


Smoke and C02 detector type and location are highly regulated in the Province of Ontario. Builders are understandably the first call when there is a nuisance alarm. The builder does not select the product nor control the cleaning, dust or humidity in a home after occupancy. 


Although a nuisance alarm is irritating, it is not an emergency as defined by Tarion, review the Chirp Codes found on backside of unit. If the issue persists, submit a ticket and we can assist guiding you through manufacture's options using the links below.
