ABSTRACT:
A concealed sprinkler assembly includes a sprinkler head having a body defining a nozzle, an arm structure extending from the nozzle and a deflector mounted on the arm assembly opposite the nozzle. A mounting or gauge base is secured to the sprinkler head. The base positions the deflector and head with respect to a ceiling. A cover plate is snapped onto the sprinkler head assembly by a pair of metal clips. The clips are fabricated from a material which returns towards an original prebent configuration upon being exposed to a predetermined ambient temperature thereby releasing the cover plate from the assembly.
