I encountered a problem while rewiring that has me scratching my head. When I powered up a new smoke detector circuit all of the detectors started sounding (as though there was a fire). The detectors do not trip when there is no AC power. There are 12 detectors in the circuit wired together with 14/3. There is less than 1000′ of wire in the circuit – actually a bit less than 250′. In addition to the smoke detectors there is are three overhead lights wired through the same circuit. The circuit is protected by a 15A AFCI breaker. Any thoughts on what might be causing this problem? Could is be dead backup batteries in one or more of the detectors? Any help would be appreciated. The smoke detectors are Kiddie 1275s/
