Things you don't expect to happen: a smoke alarm to continue going "BIP!" after you've removed the battery from it.

Everything here apparently runs on pixie dust...

Some alarms are also wired into the mains, with the battery theoretically just for backup (it still eventually runs down though).

That's the case with the smoke alarms here. It also means that when you burn the toast, *all* the alarms go off. And there's no "It's only the toast!" button on them.

Curiously the smoke alarm (actually a heat alarm) I had down had a sticker stating "This heat alarm will not operate without a working battery".
