smoke detectors

i am confused over the NEC language on wiring for smoke detectors, my interpretation is for a new house they must be hardwired but for an existing structure/remodel(not an addition) - battery operated is ok is this correct?

I don't have my copy of the NEC with me, but as I remember, smoke detectors are regulated by building codes, not electrical codes. Because there are local variations on smoke detector codes, I suggest a quick call to your building department can clear up your question.

P.S. My interpretation is the same as yours, but that doesn't count for much.

New work is hardwired and all units must go off if one is activated. I could swear they buried it the code somewhere but I cannot find it right now. It may be in Special Equipment. I remember seeing it, but not sure where.

All my sources say BOCA and/or CABO.
