Smoke Detectors
Couple of questions on smoke detectors wired in series.
1) Do they have to all be on the same circuit?
2) Do they have to all be on the same circuit even if they are on different floors?
3) Can any other fixture / receptacle be on the same circuit as the smoke detector?
Thanks,

Smokes:
The have to be installed all on the same circuit, because of the interconnection wiring between them (3 conductor). They also have to be battery back-up. They may share a circuit, but what I have seen to many times is their electronics don’t much care for power consumption from other devices, and this creates a "chirp" every time a switch or app. ext. is turned on.
