A FDC sign (Fire Department Connection) is placed around the area where the fdc is located. Fire department connection is a connection on the exterior of a commercial building where a responding fire department can attach a fire hose and pump water into the building"s stand pipe system supplementing water pressure into the building's sprinkler system. The traditional FDC connection consists of a brass fitting in the shape of a Y protruding from an outside wall of the building. This is known as a Siamese valve as it usually has two 2.5" female fittings that allow water to flow into one 4" pipe on the interior of the wall. We at hpd signs carry all types of FDC/Fire department connection signage.
