ABSTRACT:
An improved concealed sprinkler head assembly that incorporates a standard pendant-type sprinkler head includes a frame having an outlet that is connected to a water line and a valve cap that encloses the outlet and is held in the closed position by a releasable lever mechanism which includes a fusible metal. The assembly also includes a pre-assembled cover plate unit that consists of a disc having a central opening that is slid upwardly over the frame of the sprinkler head. The cover plate unit also includes a tubular sleeve having a pair of opposed notches which receive projections on the periphery of the disc. A decorative cover plate is secured through a fusible metal, such as solder, to the lower edge of the sleeve, and a coil spring, in a compressed condition, interconnects the upper end of the sleeve with the disc.
