Question: Some of our smoke detectors have lost AC power. I've tried looking for loose connections in adjacent detectors and close-by receptacle/switch boxes, but have found none.
Question: My hard wired smoke alarm system has red black, white wires leading to the smoke alarm. Does the red have power to shock me? Should I connect the third wire in the smoke detector to the red wire (inter-connect)? I have connected white to white and black to black.
Question: I have an electrical smoke alarm and it'll sound off in the wee hours of the a.m. It doesn't happen every night, but it happened this morning.
