Does anyone have a link to the recommended wire classes and sizes for various sensors, like DC smoke alarms, PIR's, glass break, magnetic contact, sirens, etc?

I think I saw a post that said there are a couple special classes of wire for at least a couple of these, but I can't locate that post again.

Most of that is covered in the Wiring Guide:

Typically, 22/2 for contacts, 22/4 for powered contacts like motions or glass breaks, and 18/4 firewire for DC smokes.
