If the garage is connected to a home by a breezeway, is it required? I should know this, but I don't. I always just do it. Im in a situation where it would required cutting alot of drywall. Thanks

Re: When is a smoke detector required in garage per NFPA
I thought smokes weren't required in the garage.
Doesn't it explicitly state in the instructions with the smoke not to install one there due to nuisance detecting?
Interested to see what others have to say.

I'll just tie the reds (conditional hots) together and use the blacks as a light. It might be a good idea any how, because if the circuit ever quits working the light will not work. Therefore the homeowner will have more knowledge of the problem through a visible source and will be more apt to fix the circuit, assuring the smokes work.
