Critique my plan for circuits
I have also been advised to include some lights on the smoke &amp; fire detector circuit, in order to give you some indication if the smoke &amp; fire has gone offline.  I believe Ed Beal's comment about 760.41.b refers to dedicated fire alarm panels, and that residential detectors are considered receptacles.

I found this https://www.electriciantalk.com/f5/smoke-detector-circuit-72368/ which addresses the question.

Of course it's always best to check with your local building department for the final say.
