We have a single floor structure that is protected by a Class-I dry standpipe that runs a partial loop around the periphery edge of the structure, with short (~5 feet) tee-offs to fire hose valves every 150 feet. This ensures that the entire structure has hose coverage. The dry standpipe is fed from multiple FDCs at street level, spaced every 300 feet (or part thereof) around the structure.
In this situation, how would you comply with NFPA 14, clause 6.5.2? See below:
"Valves shall be provided on all standpipes, including manual-dry standpipes, to allow isolation of a standpipe without interrupting the supply to other standpipes from the same source of supply."
Where would one place the valve(s), given the multiple sources of supply via FDCs?
