Just a quick question, I am in the process of finishing the basement and need to run a few additional smoke detectors. The one that is currently down there has 12awg wire to it. Can I use 14awg wire off of that one to the additional two that I need to add?

Depends on the breaker that feeds the smokes, if it is 20 amp you need to use #12 wire for the extension. If it is 15 amp (doubtful), you can use #14.

Yeah it is a 20 amp breaker. I kind of figured that I would need to use 12awg but I just thought I would ask. Thanks.
