The Cooler is a closed in room with a space above. You calculate all the heads inside the cooler if less than 1500 SF. If the area outside the cooler is fully sprinklered then you probably have performed calcs already. I'd ask the AHJ to review NFPA 13.

I calc'ed the entire area of the cooler and submitted. The AHJ is telling me that I need to calc additional sprinklers at the ceiling to have a 1500 sf design area. I don't think I need to do this, I was looking at this as a separate fire area, and I don't see it being much different than not adding heads below ducts or other large obstructions. Do I need to calc additional sprinklers at the ceiling for this application?
