I’m roughing in a couple of interconnected smoke/co detectors and am unsure about what wires are needed between the two smoke detectors. I have power coming into the ceiling box of the first detector on 12/2. Do I simply run 12/2 from the first detector to the next detector? Or do I need to run 12/3 between them? What provides the interconnect?

12/3 . Connect signal wire to red per detector mfr directions. If on 15amp ckt can be 14/3 I believe.

Wait for confirmation from the pro/experts here.

Same here.
Blk/wht to the first detector.
Blk/wht/red to the next, and continue same to all others.
Sure is easier with 14awg than 12.
