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. If you have interconnected alarms, the first step is finding the initiating unit, as that is the key. See the owner's manual. Avoid putting the alarms 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

I have a small 10x10 room and the detector works for about 18 months and then I need to replace it. So this product is pricey for the safety.
Works but so expensive
