Ray, Your observation is acknowledged, however there are those that lump all FDC's as supplemental across the board. Maybe this "supplemental" thinking has gone too far.
John ---------------------------- Ray wrote; As a side note, if the FDC is provided specifically for a standpipe or combination standpipe sytem in a "manual-wet" scenario, then it IS designed to provide the full flows and pressures of the standpipe system, keeping in mind the requirement to calculate the demand back to the FDC connection so the piping is sized to overcome the appropriate friction losses and elevations. Always be sure you coordinate the local fire department's ability to provide the required standpipe demands and/or keep the required pressures on the downside of 150 psi at the FDC.
