Looking at NFPA 2007-8.6.4.1.1.3 commentary adresses changes in height and it seems the key is if the change in elevation is 36" or greater, wherein it is treated as a wall and would need protection.
Forest Wilson Cherokee Fire -----Original Message----- From: Ed Cyr <[email protected]> To: American Fire Sprinkler Association <[email protected]> Sent: Wed, Aug 26, 2009 1:47 pm Subject: ceiling pockets? Forumites, Question: Are sprinklers required in the narrow pockets parallel to windows long with smoke detection? Construction is non-combustible concealed space, smooth t-bar ceiling with coustical tile, ceiling stops short of window fronts, ceiling changes levation by rising up to meet window framing as to not terminate into lass. Pocket ranges from 6” -12” from glass and rises 3 feet and higher, ockets can be 6 feet or more parallel to the glass. Pockets are not open to he concealed space. Sprinklers in lower ceiling are spaced to the windows. This is a Hospital, California OSHPD guidelines. NFPA 13, 2002 standard. IOR says we need sprinklers and smoke detection, I say no. Any response would be appreciated Thanks, d Cyr lpha Fire Sprinkler Corp. an Luis Obispo, CA ______________________________________________ prinklerforum mailing list [email protected] ttp://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum
