I am having problems with my smoke alarm, it won't stop beeping! I tried changing the battery and that helped for about a half an hour. When I got home from work today it was beeping again. I took it down and noticed all of these wires underneeth, I assume that means it is hard wired. I looked for a switch on my breaker, and there isn't one. It is too late to go to the store, what do I do?
