Customer Reviews for Kidde 10-Year Worry Free Smoke & Carbon Monoxide Detector, Lithium Battery Powered with Photoelectric Sensor

Hello. False alarms are most commonly caused by something interfering with the sensor. To clean the alarm, hold the unit by its edge and thoroughly blow through the gap on the side of the unit with compressed air (like keyboard cleaner). We recommend cleaning out all of your smoke alarms at least every 6 months to a year and at this point we would recommend cleaning out all of your other alarms as well as a preventative. Some of your alarms may be in one the locations to avoid listed in the owner's manuals. This would especially include alarms being installed within 3 ft (.9m) of a forced air supply ducts used for heating or cooling, ceiling or whole house ventilating fans, or other high air flow areas. We recommend that alarms not be installed near vents, flues, chimneys, or fans. We recommend that alarms not be installed near doors or windows near areas directly exposed to the weather. We strongly recommend not to install these alarms in garages, attics, and crawl spaces as you will get temperatures, dust, insects, and chemicals that can cause nuisance alarms. Try cleaning out the alarms. If you have the issue again, call us with that alarm in hand at 1-800-880-6788 so we can get this resolved for you.
