Abstract (en)
A fire suppression method and apparatus has a sprinkler head support bracket which is installable immediately above a ceiling tile. The support bracket is configured with a plurality of openings such that multiple locations for the sprinkler head may be used and the exact "center of tile" installation of the sprinkler head can be accomplished with a wide variety of suspended ceiling assemblies and sprinkler heads. The support bracket rests on grid support members and arches over the ceiling tile. Hold down clips are provided to maintain the bracket in position relative to the grid support members. A pipe clamp is provided which is insertable within the bracket to retain a drop nipple within it. The drop nipple is adjustable relative to the horizontal to move it upwardly or downwardly relative to the ceiling tile. The opposite end of the flexible armover connector is attached to an adapter nipple. The adapter nipple is formed from a single piece of black steel material. The adapter nipple has a central tubular portion to either end of which extends an opposing external threaded end portion. Inwardly of one end portion is an internal chamfer. <IMAGE>
