Assuming it’s the same specs the UFC has recently changed to in the last year. FM design requirements for Ordinary hazard I are a big jump from NFPA. Not sure if it is a change from before not having don't one in while myself. But for a 30'-0" of less ceiling building you need 0.20/2500 with 8.0K heads and 250 hose. This is per FMG Engineering Bulletin 4-12. Maybe you'll different criteria.

I haven’t worked with FM for a while so what are the main differences between NFPA 13 and FM? The plans have already been approved by the AHJ so the owner is looking for any potential cost impact. I know that the products used should be FM approved. I did take a reduced design area for my light hazard areas.
