Steve, I thought that as well, but in all my musings I also figured that the sprinklers at the cloud level were more likely to operate than say a sprinkler under a duct. I also figured in my little head that sprinklers would activate at the ceiling level as well. I understand what your point is, but how do I substantiate that with code to the inquisitive AHJ? The same would be for Thom's suggestion of two.

NFPA 13 is clear on the intent the only the most demanding complement is required to be calculated.

I will have a 1500 sf area w/ no reduction. I will obviously be calc'ing all the uprights w/in the design area, but what about the pendent's in the clouds? Do I calc all the ceiling cloud heads w/in the DA? Two heads?
