My smoke alarms are all connected, and there is no fire. It keeps going off, and I can't figure out how to get it to stop chirping, flashing, and then going off. This is the 3rd time it's gone off since 1:00 AM, and I can't sleep. I've checked the whole house, and there is no fire. I'm sure it's just a low battery. I got out a ladder to find the battery, but I can't find it. Is there a way to temporarily disconnect until the morning? Please? Anyone? Thank you!
