The answer to your question depends on whether the wood is fire retardant treated or coated. Treated (as in pressure treated) wood qualifies for the omission. Coated does not.
It should be recognized that the above is my opinion as a member of the NFPA, and has not been processed as a formal interpretation in accordance with the NFPA Regulations Governing Committee Projects and should therefore not be considered, nor relied upon, as the official position of the the NFPA, nor any of their technical committees.

I have a metal building with acoustical ceiling tiles. Above the ceiling they have framed with metal studs and fire rated plywood a mezzanine for the AHU's to sit on. These are electric and not gas fired. For some reason I recall reading that if the AHU's are not gas fired then no sprinkler protection is required above the area of the mezzanine. Can someone please clarify?
