Why isn't the FDC supplying an automatic wet standpipe system considered supplemental as well then? The required demand for the standpipes are met by the sprinkler system but NFPA 14 still requires a 2 1/2" connection for every 250gpm demand? Dewayne

Since one has to also calc the system demand from the FDC, has anyone looked at the maximum flow they can get through a single 2-way FDC and still meet their design demand?
