Abstract: A fire suppression sprinkler assembly coupled to a mounting surface includes a sprinkler having a heat responsive element arranged adjacent a first end. A cover plate is positioned adjacent the heat responsive element and includes a thermally conductive cover layer. A reflective shield has a reflective interior surface. The reflective shield is positioned substantially opposite the cover plate adjacent the first end of the sprinkler such that heat reflects from the top plate towards the heat responsive element.

Abstract: A water seat is provided for use in a fire suppression sprinkler. The water seat is movable between an inactive position and an active position. The water seat includes a generally polygonal guiding surface in limited contact with the sprinkler. The water seat is slidable relative to the sprinkler when corrosion residue is present within the sprinkler. A sealing surface is positioned adjacent the polygonal guiding surface and forms a line contact seal at an interface with the sprinkler when the water seat is in an active position. The water seat also includes a guiding portion adjacent the sealing surface and opposite the polygonal guiding surface. The combination of the guiding surface and the guiding portion maintain a generally parallel orientation of the water seat relative to the sprinkler when the water seat moves from an inactive position to an active position.

Abstract: An exemplary flexible conduit (26) for use in a fire suppression system (20) includes a core layer (30) that establishes interior surface (32) of the flexible conduit that is configured to contact fire suppression fluid. A jacket layer (36) surrounds the core layer. The jacket layer establishes an exterior surface (38) of the flexible conduit. A reinforcing layer (34) is situated between the interior surface and the exterior surface.

Abstract: An exemplary method of fire suppression includes introducing a fire suppression fluid into an area by directing the fire suppression fluid along a primary trajectory that is aimed directly at a generally horizontal surface in the area.
