Smoke detector problem, need help!

So what does it mean when you replace with new detector with new battery and it still chirps in the evening at random times? I went through and replaced the detectors only to have one chirp. Light will blink red every once in a while. Pulled battery and reset the unit. Still problems. Is it defective? My system links all of them with hardwire plugs with battery back up. Some suggestions have you install with power off then turn breakers back on.

Suggestions?

Maybe blow it out with canned air-sometimes mine chirps if I don't clean it.

PSA: CO detectors have a mandatory 7 year service life. It will start chirping 7 years after you first plug it in, they have to be replaced. So if you hear a detector with one chirping, and battery replacement doesn't work, you gotta replace the damn thing.

Must be a residential only thing? My RV CO detector is 11 years old.

Ionization detectors have americium 241 in them it has a half life.

Impacts will also take out a detector. Dropping from waist high or more is bad

Loose plugs sometimes cause intermitant false alarms as they will chirp when the power is off. Also loose wire nuts.

I've been in the same boat, nothing like a hidden chirper that drives you nuts

I would agree with having to replace them. I had to do the same with mine. They were 7 plus years old. Fixed the problem. They were just old

BOY DO I FEEL STUPID!! I found a CO detector hidden behind the dresser in the bedroom. Dammed if it wasn't the one making the racket. At least we'll be able to sleep tonight

And I like your Title too.
