re: Smoke detector wont stop beeping every 30 seconds

I don't know what model we have... but I had to deal with this last night. The detectors are all hard wired in electrically and to the alarm system, but they also each have a backup battery (9 volt) in them. I replaced the backup battery and all is well.

What was weird was... it wasn't chirping at a constant rate. It would chirp, then wait 30 seconds, then chirp, then wait 10 minutes then chirp, then wait 5 minutes then chirp, then chirp every 5 seconds for a minute, etc.

When I took it down to replace battery some dust did fall out.

Throw it in a fire to show it who’s boss.
