Recessed Installation of smoke detectors allowable?

I have a residential project where the architect wants to recess the smoke detectors/ combination CO device into a slatted ceiling treatment.

My AHJ has basically refused to give specific guidance and I am looking for opinions on if this is legal. My reading of NFPA 72 indicates that installation is only allowed on a smooth, flat ceiling and does not mention recessed mounting.


Any suggestions?
