This is the code we use to support our findings: NFPA 101 (2012) 8.5.6.4 Where sprinklers penetrate a single membrane of a fire resistance rated assembly in buildings equipped throughout with an approved automatic fire sprinkler system, noncombustible escutcheon plates shall be permitted, provided that the space around each sprinkler penetration does not exceed 1/2 in. (13 mm), measured between the edge of the membrane and the sprinkler.

I know that I have always written it up as a deficiency if the tile was out within a 5ft area around the sprinkler. if it's a small closet or storage room and its missing a tile or two, then I have written it down as a deficiency as well due to the potential for the heat loss not allowing for the activation of the sprinkler. As for the missing escutcheons, (this is my opinion) I don't see why they wouldn't be a critical deficiency due to the listings on the sprinklers. The sprinklers are listed with the plate to be installed in the manner for the plate that it was installed with ( recessed, flush, Concealed, 401). But you are definitely correct in the statement that this is a gray area in NFPA #25. I guess if we step back and think about the original installation of the ceilings and sprinklers, when the system was bought off by the fire marshal, wasn't it required to have all the tile in at the time of his walk through? So why wouldn't the building still be required to have all the tiles in place on a NFPA 25 inspection.

It does not specifically mention it, but it is a non-critical deficiency if it is missing escutcheons and cover plates on semi-recessed, recessed and concealed sprinklers. Wouldn't missing ceiling tiles create the same problem in a room with a drop ceiling? I would think it would really screw up the air flow of heat to the sprinklers if there are 2' X 2' or 2' X 4' holes in the ceilings. *Jay Stough* NICET IV LAYOUT NICET III ITM _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org
