I’ve only been in 2 people’s houses where the smokr alarm was doing the battery chirp. Like… Get a new battery for it! Or, hell, take the near dead one out so it at least stops beeping. It probably doesn’t habe enough juice to actually function in the event of a fire, anyway. At least it doesn’t need to be annoying.
I’m not exactly sure how smoke alarm logic works, but at least in my current and previous house, once one starts beeping all the ones in the house start; and removing the offending one doesn’t always stop the others.
