His stand is that I have one of three options that I have not used: (1) Density/area curves of Figure 11.2.3.1.1 in accordance with the density/area method of 11.2.3.2 (2) The room that creates the greatest demand in accordance with the room design method of 11.2.3.3 (3) Special design areas in accordance with 11.2.3.4
Keep in mind that this is a jurisdiction that has told me in the past that you can't use the exceptions in 13 (this was before they became part of the body), and that they can't use common sense.

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. Regards, G. Tim Stone G.

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?
