I’ve seen this condition happen pretty regularly. I’m not aware of anything prohibiting it. I suppose you are concerned about the potential impact to sprinkler activation?

I should have clarified they are roof top exhaust fans.

Initially, the locations were coordinated with the mechanical contractor, and our branchline locations, however, his plans were never updated. The exhaust fan curb and gutter roof penetration is located directly below our sprinkler. The exhaust fan itself is located on the roof, and the louvers are flush with the roof deck on the interior. There is no obstruction that is created, but I can't find anything in NFPA 13 that would address this issue. Is this an acceptable situation?
