I am not sure this qualifies as a combustible concealed space (combustible enclosure being key words) as much as a ceiling mounted obstruction. Your situation leads me more along the lines of the obstruction rules (8.6.5.3-2007).
8.15.1.6 also specifically calls out wood truss/joist/double wood joist..also a disqualifier for your described situation. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Todd Williams Sent: Thursday, February 18, 2010 1:13 PM To: [email protected] Subject: Spklr in non comb space I am working on a classroom building with cloud ceilings in each of the classrooms. Construction is concrete on steel beams. Sprinklers are to be installed bothabove and below the cloud. The space between the ceiling and the deck is 2'-6". 8.15.1.6 calls for concealed space sprinklers in combustible concealed spaces of 3'-0" of less. Am I correct in assuming that I can use regular upright sprinklers in this situation since the space in not combustible? Todd G.
