Quoting: Anonymous Coward 1382127 When I was a residential electrician, all the newer home smoke detectors got wired together. If you take one down you'll see that theres a black, white, AND a red wire. The red wire inner-connects all the smokes. That's why they all went off at once. They're not your mommas old smoke detectors. I hope this helps.

If they're the hardwired kind, they'll be linked together, so if one gets dusty and has a false alarm, they'll all go off.

Could be a bad 9-volt or just loose wiring on the 3 wires ... check the wire nuts, but turn the power off first.

NEC makes smokes have their own designated breaker. Usually if the battery is low they chirp. Good call on that one DOOMBREAKER!
