In regards to installing pressure reducing stations for separating areas of the building into different pressure zones, NFPA 14 calls out that the FDC needs to be installed downstream of the pressure reducing valves.
Is a separate FDC required for each pressure zone?
If you provide just one FDC, and the fire department supplies the system for an upper floor of a high-rise, you will exceed the maximum working pressure of the lower systems. I'm not sure how that's possible to avoid.
