You replied to a post I made yesterday about the ceiling drywall. Take a look at my response.
I have an AC powered smoke detector. I am replacing it with a newer one, plus I want to add a separate one for carbon monoxide detection.
The AC power to this thing seems to be always on. I can see that you might not want it on a breaker with other electrical outlets or appliances, but I can't shut down power without killing power to the whole house.
Do most electrical codes allow smoke detectors to be not protected by a breaker?
