I hate that. Since ours were installed at the same time when I hear that irritating chirping we change all the batteries.

They have a compaciter in them so they can still chirp without batteries or electricity. If replacing the battery still makes it chirp, it's time to replace it.

They must be hard wired into the electrical system then.
