That’s not my situation, as the pitch is strictly at the top level. Imagine an 11 storey tower, roughly 25 x 25 ft, with an 80 ft high peaked roof above it. There is only one sprinkler at the top level, and about 4 sprinklers at each level beneath it. The tower has an open staircase within it so all of the levels are communicating. My question is do I include sprinklers on multiple levels or just one level at a time?

At the peak, there is a single sprinkler head, with the lower levels having between 2 and 4 sprinklers at each level. I am having a problem determining the heads to include in my design area. The levels are not closed off from each other, so I think that restricting the calculations to one level would not be conservative enough. I have not found any guidance in NFPA 13. I would appreciate your thoughts about this issue. David Bitton, ing./Eng. Quest Loss Control Services Inc.
