Definitely true!
My smoke alarms started sounding at 5:15 a.m. this morning and wouldn't stop. A full blown alert not just the battery going bad chirp. Got up and checked the entire house....nothing. They wouldn't stop. Took batteries out....didn't work. Finally, I had to unplug them from the ceiling. (My poor, poor babies) Must have a faulty one in the circuit that needs replaced. Get to work, and my boss is in some kind of mood! Whoa. Just get me to 5:00 p.m.....
