Replaced one of our old carbon monoxide detectors. It is mounted on the wall well. My wife was worried it wouldn't wake us up. Needless to say we tested that theory one night, on purpose, and it woke her right up and when she did it to me it woke me up. No, we didn't set a fire we just hit the test button. But it's loud enough to wake you out of a dead sleep.
