Title: FIRE PROTECTION NOZZLE, FIRE PROTECTION SPRINKLER, FIRE PROTECTION SYSTEMS, AND METHODS OF MANUFACTURING A FIRE PROTECTION NOZZLE AND A FIRE PROTECTION SPRINKLER
Abstract:
A fire protection nozzle includes a body having two frame arms having proximal ends connected to an outlet of the body, and distal ends, the two frame arms defining a frame arm plane, and a junction formed by the distal ends of the frame arms, the junction including a central bore and a cylindrical outer wall. A circular deflector is mounted to the body, and includes a planar disk having a mounting hole in a center of the planar disk to receive the cylindrical outer wall of the junction, and a plurality of slots on a periphery of the circular planar disk. The plurality of slots includes four radial first slots, four radial second slots, eight radial third slots, and eight fourth slots. The nozzle has a K-factor of at least 28 gpm/(psi)1/2.
