Do you just mount the strobe to the box only or is a 4" plaster ring needed?
Most of them now will mount to most any type of box 4" square, 1 gang ring, 2 gang ring or octagonal box. (Google system sensor P2R)
This issue becomes when the box is installed in a sheetrock wall, the common box mounting methods take into account the installation of a plaster ring so the box mounts flush to the stud face.
Without the ring, the box often sits back behind the sheetrock. Not many electricians take that into account, so I include the ring when doing a take off or ordering material.

I know they must be in a box... It was the ring I was asking about
