Dennis, Hear in Ashville most of us have the smokes on a seperate circuit and they are linked togeather so if one goes off all will go off. One in each bedroom, outside of each bedroom and on each floor including basement. I wire them on 14/2 for the first one and 14/3 between smokes. In the smoke dector box thats what the instructions say. Semper Fi.Dennis Alwon said:You need to check with your local authority. Here in NC they use to require the smokes on a circuit with the lighting but it is not required any more. We never had to have them on a separate circuit.
Remember they have to be on an arc fault circuit when they are installed in a residential bedroom.
BTW-- this is not in the NEC but a building code issue

winnie said:IMHO it is _good design_ to place the smokes on a circuit shared with some small but frequently used loads, eg. the front hall light. Ideally _not_ lights that you would want on when working on a detector

Dennis Alwon said:Exactly-- I agree wholeheartedly. I am curious as to why our state changed that ruling.
What building code would that be? I've got the IRC and the IBC at hand, and neither one says any such thing.donselectric said:i think if you read the building code they say lighting cir
Cavie said:THe NEC does not require smokes be on AFC. They end up there by default because the are reqired to be in the bedrooms in which all outlets are required to be AFC therefor they also end up on the lighting circuit so you will know they have power on them.
