NFPA 72 addresses curved ceilings, and I think you have done as it calls for.
These are heat detector activation rules, and of course, closed sprinklers are nothing if they are not heat detectors first :) Brad _____ From: Sprinklerforum [mailto:[email protected]] On Behalf Of Tim Stone Sent: Friday, November 18, 2016 9:37 AM To: [email protected] Subject: Curved Roof Line In determining the increase in design area per 11.2.3.2.4 as applied to a curved ceiling/roof line, how do we measure the roof slope? I have drawn a straight line between the peak or highest point of the curve down to the eve and measured the slope to be 2:12. The straight line slope does not exceed 2:12 which would require the 30% increase. Due to the curve is it ok to treat this as a flat ceiling when applying the "Slope Ceiling" criteria? Thank you.
