Fix Smoke Detector Alarm Chirp

A smoke detector will chirp at regular intervals, about once a minute, when the battery is weak and needs to be replaced. So, the first thing you should do to fix smoke detector alarm chirps is replace the battery. If the chirping does not stop, check to make sure that the battery is installed correctly and not loose. Also make sure that the smoke detector inside and out is clean of any dust and insects. It is a good idea to get into the habit of cleaning the unit whenever you replace a battery. If the smoke detector is still chirping, try manually resetting the unit. An electrical condition such as power surge can also cause a unit to chirp. If none of the above suggestions fix the chirping, and the unit is hard wired, have an electrician come in and look at it. If all else fails, and the unit is still chirping, replacing it may be the only other option.
