In a building recognized as part of separate fire areas, the annex material in NFPA 14 Section 7.10.1.1 states the the total supply can be calculated based on the single bldg/ fire area requiring the greatest number of standpipes. In this scenario, the physical separation between fire areas is functioning as a horizontal exit requiring a hose valves at the horizontal exit. One side of the wall meets the 100 ft. + 30 ft. hose stream exemption while the other side does not. The hose valves will be fed via an independent vertical standpipe riser. Is this hose valve located at the horizontal exit calculated as part of the area it is located in or calculated as part of the building it serves on the opposite side of the horizontal exit? I thought this was addressed somewhere in 14 but I can't locate it.
Can anyone help me out this afternoon? Zach
