How to stop a Smoke Alarm from beeping or chirping when there is NO SMOKE and you have replaced the batteries. Our smoke alarm/smoke detector was beeping and going off at night so we changed the smoke alarm batteries and it was still chirping.
Why is your smoke alarm beeping or chirping? Its probably because it is dusty!
Here is a quick 1-minute solution to fix beeing and chirping smoke alarms. Grab a vacuum and vacuum the smoke alarm to remove the dust from the vents. This should stop your smoke alarm from going off randomly for no reason.
