Take a look at 8.8.4.1.1.4 (2007), you should be fine so long as you don't start getting into unprotected ceiling pockets....

This situation occurs in a repeating pattern over a large section of floor area. At the top of the curve there is a small slot that serves as a return air opening. The design intent was to use concealed, quick response, ordinary hazard, extended coverage sprinklers located in the flat part of the ceiling. The question is "this a flat ceiling?". Does the portion of the ceiling that exceeds 2:12 nullify the use of the flat ceiling design? _______________________________________________ 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 _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org
