I use the 12" from the ceiling then protect under obstructions over 4' wide rules. With that simple explanation I've never had an arch not get it. Of course I've never had an arch care about above the ceiling. Just why we're putting them in their clouds.

OK here is my situation, the room has a ceiling that the opening between the wall and ceiling is 24" wide. The room is approximately 24' wide by 40' long also in the middle of the room is a 24" wide gap between the ceilings. The ceiling height is 9'-0" A.F.F. and the roof deck is 14'-0" to t.o.s. The Architect can not understand that this room needs sprinkler protection above and below. Now where in NFPA-13 do I find this requirement?
