What type of wire (14-2 or 12-2) should be used to connect detectors on a new installation?


14-3 w/a ground

14/2 is adequate due to the load, but most wired systems are three wire so that the smoke detectors communicate with each other. Check into how this is done before you buy anything or wire anything
