Why is my smoke detector beeping or chirping every few minutes?

Most likely the battery needs to be changed. It is a good idea to change the batteries every six months. If smoke detectors continue beeping after adding fresh batteries, it could be time to replace them. It is recommended that smoke alarms be replaced after 8 to 10 years.
