Steve, Yes there is a hose connection at the first floor landing of the remote stand pipe. Yes there is access to occupied first floor space via the exit passage and the remote stairway. Thanks

And is there access to occupiable areas on the first floor from the passageway or stairwell? Obviously, two or more hose connections supplied by a feed main on a single floor is a horizontal standpipe by definition, but it would seem to me that in this type of egress system that would be redundant or not of value depending on where a firefighter would be going with the water after connection to one or the other hose connection. The foregoing does not represent any opinion or interpretation of the standard on behalf of NFPA or the NFPA 14 Technical Committee.

The remote stair is on the interior of the building and has a rated exit passageway on the first floor that is 73' long. I am placing all hose valves on the main floor landings and one a the exit door of the exit passage way. I am planning on calculating 500 gpm from the remote stand pipe and 250 for the 2nd standpipe. The exit passage way hose connection will be fed by a 2/12 lateral pipe fed from the 4" horizontal supply to the remote standpipe as it pass by the exit passageway. Do I need to include an additional 250 gpm in my calcs at the hose valve at the exit passageway? Thanks Christopher S. Wilson SET Project Design Manager Treasure Valley Fire Protection 2731 S.
