How to Make a Smoke Detector Stop Chirping

REPLACE THE BATTERIES - The first step in how to make a fire detector stop chirping is to replace the batteries. Unscrew the fire detector and check which batteries your model takes. Replace the battery and return the fire detector to the ceiling.

DUST THE FIRE DETECTOR - If your fire detector continues to chirp, try dusting it. Owners are supposed to dust their fire detectors two times a year. There is often dust or spider webs in the sensor. Remove the fire detector and batteries and use your vacuum brush to dust thoroughly. Return the fire detector to the ceiling.

REPLACE THE FIRE DETECTOR - If your fire detector is still chirping, there is a chance that the battery holder or the circuit has gone bad. If your fire detectors are interconnected, buy the same model and replace it. Fire detectors are rather cheap and the absence of chirping and feeling of safety will be well worth it.
