Abstract

A dry sprinkler has a casing tube having an inlet orifice and an outlet orifice. When the sprinkler is in a non-actuated state, an inlet seal assembly operatively seals the inlet orifice and an outlet seat assembly operatively seals the outlet orifice. A translating member extends through the casing tube between an inlet and an outlet. The translating member axially translates from a first position, in which the translating member retains the inlet seal assembly in a sealed state, to a second position, in which the translating member releases the inlet seal assembly, toward the outlet when the outlet seat assembly is released. The sprinkler has a nominal K-factor greater than 17 gpm/(psi)1/2. A difference between a cross-sectional area of the casing tube and a cross-sectional area bounded by an outer perimeter of the translating member is more than 30% of the cross-sectional area of the casing tube.

Abstract

A support bracket for use in installing a sprinkler fitting for a fire protection sprinkler in a building. The support bracket includes a support beam and a center bracket. The center bracket has a body that defines an opening to receive a sprinkler fitting, and a closure assembly, including a closure member having a first end rotatably connected to the body, and a second end having a handle. The closure assembly is movable between an open position and a closed position. When in the closed position, the closure assembly presses the sprinkler fitting against one of the body and the support beam, thereby urging the center bracket against the support beam to maintain the center bracket stationary relative to the support beam. In addition, the closure assembly includes a lock that engages with the closure assembly when the closure member moves from the open position to the closed position, and that prevents the closure member from returning from the closed position to the open position.

Abstract

A pressure maintenance device is connected to a fire protection sprinkler system having downstream piping that is exposed to freezing temperatures, and supplies a pressurized fluid to the downstream piping when the sprinkler system is in an inactivated state. When an outlet pressure sensor near an outlet of the pressure maintenance device detects that a pressure of the pressurized fluid downstream of an outlet regulator falls below a first predetermined pressure, the pressure maintenance device supplies the pressurized fluid in a primary supply mode or a secondary supply mode. The pressure maintenance device automatically switches from the primary supply mode to the secondary supply mode if a supply pressure sensor detects that a pressure of the pressurized fluid downstream of a first pressurized fluid valve, and upstream of the outlet pressure regulator, falls below a second predetermined pressure.

A horizontal sidewall fire protection sprinkler has a deflector having a vertical face, transverse to the fluid flow from the output orifice, and a horizontal shelf positioned above and perpendicular to the vertical face. A portion of the horizontal shelf extends in the fluid flow direction by a first length, with respect to the vertical face, and this first length is less than about half of the total length of the horizontal shelf in the fluid flow direction. The sprinkler may be installed in a support cup having a raised mounting platform configured to receive the sprinkler body and a cylindrical outer surface. A horizontal or pendent fire protection sprinkler has a body having an output orifice and a flange and a seal cap to seal a flow of fluid from the output orifice and a thermally-responsive element positioned to releasably retain the seal cap.
