Abstract: A system and method for providing a fire department connection (FDC) to a building fire sprinkler and/or standpipe system comprising carrying and transporting the FDC on a pumper truck with the fire department. The FDC is removed from the pumper truck and coupled to the inlet of the building with a quick-connect. The quick connect is capable of releasably coupling the FDC to the building inlet of a building fire sprinkler and/or standpipe system. When finished, the FDC is removed from the inlet of the building and replaced on the pumper truck.

Abstract: A fire sprinkler valve trigger has a body or tube segmented into opposite segments joined together at a joint by a fusible material with a predetermined and selected melting temperature less than a melting temperature of the opposite segments. An exterior of the body or tube comprises a layer added to the exterior, and comprising a preselected color corresponding to and designating the melting temperature of the fusible material. The body or tube, including the joint and the fusible material, being exposed and visible so that the layer on the exterior of the body or capsule is exposed and visible.
