Many smoke detectors only last for 10 years. What you’re describing is what mine did in my house when they hit the 10 year mark. If you remove it from the ceiling, they usually have a human readable date printed on the ceiling facing side of the smoke detector.
I’m betting if you pulled one of your “one chirp” smoke detectors down, you’ll find a date more than 10 years ago printed on it. Buy new ones, dispose of these. Note on disposal: old school smoke detectors contain a very small amount of radioactive material. If you have one of these there will be a radioactive logo on it **PLEASE DO NOT PUT THIS IN THE LANDFILL TRASH! ** Please dispose of these and your registered hazardous waste site.
Newer style smoke detectors don’t use radioactive material and instead use regular light sensors. These are safe to dispose of as regular ewaste.
