Multiple FDC on large buildings is a common occurrence on industrial sites. FDCs are commonly tagged with the building number and/or system number to which they are connected. Local FDs are familiarized with the facility and often know more about the protection systems than the owner.
I've have not experienced a fire dept. that rolled on a call and upon arrival couldn't figure out what to connect to. It's part of their job to know, their lives may depend on it. So multiple FDCs on a building is typically not an issue. Craig L.

Which FDC should be charged in a fire event? Pre-fire planning, signals from FACP, dispatch, FDC signage all come into play. J. Scott Mitchell, PE Senior Fire Protection Engineer Mission Engineering CNS Y-12 | 865-576-5258 CNS PTX | 806-477-5883 From: Sprinklerforum [mailto:[email protected]] On Behalf Of [email protected]<mailto:[email protected]> Sent: Monday, February 06, 2017 10:40 AM To: [email protected]<mailto:[email protected]> Subject: RE: (1) FDC or (2) I'd provide 2 separate FDCs, one attached to each riser if there is no issue with access. If they were connected and one system was taken out of service due to some event (fire, explosion, weather related) and the piping system was compromised, the FDC would be useless for charging the other system. I've seen warehouses where one system had been compromised, one by building collapse in a fire event, one where the building was hit by a microburst and a wall was taken out, which broke the fire main. The other portions of the buildings affected were still operable since they were completely separated. Let each system stand alone. Craig L.

The architect has requested that a single FDC be located on the corner of one of the building sides. Is it feasible to do this and tie the systems together via the FDC pipe or does each Riser still require its own FDC connection? Brian Harris, CET BVS Systems Inc.
