ABSTRACT:
A concealed extended coverage quick response sprinkler has a sprinkler body with an axial passage for water, a cap normally closing the axial passage, and a thermally responsive structure supported from a pair of frame arms retaining the cap in position. A deflector slidably supported from the sprinkler body includes a substantially planar imperforate plate with opposed peripheral edge portions disposed on opposite sides of a plane containing the frame arms which are bent away from the sprinkler body. The sprinkler has a K factor of about 11.4 and provides quick response for light hazards at spacings up to 18 feet and standard response for light hazards at spacings of 20 feet.
