Smoke Detectors not required to be on arc faults

And I think you guys are putting way to much thought into it.

Just get'er done.

I agree. When it comes to residential, that's what I do.

It used to be we would put our smokes on a first floor lighting circuit because that would probably be the soonest detected tripped breaker.

It was a few years after the AC battery backups became mandatory before I realized I didn't need to do that anymore.

You still have to feed them from a circuit with other stuff on it. Mass building code.
