indicated that the elevator meets the ASME requirements. However, the shaft must
be of non combustible construction. Gypsum wall board covering wood frame
wood not fall under non-combustible. If the elevator shaft is complete built of non
combustible construction then the sprinkler head at the top of the shaft will not be
required. NFPA 13, 8.14.5.4

Another sprinkler head is needed closer to the wall, probably along the 2 inch

this apartment. NFPA 13, 8.1
