Abstract: Installation and protective devices for fire protection sprinkler assembly having a support cup is disposed about the sprinkler assembly. A protective cap engages the support cup to define an internal volume to enclose the sprinkler therein and protect operational components of the sprinkler during storage, transport, installation and when awaiting to be placed into service. The protective cap defines a tool path with slots of the protective cap in fluid communication with the internal volume. The protective cap and tools are configured to cooperate with one another to permit the tool to adjustably navigate within the internal volume to access the protected sprinkler for installation or adjustment of the sprinkler frame and/or for removing the protective cap.

Abstract: Attic fire protection systems and methods for the protection of sloped attic spaces having large roof spans over eighty feet up to one hundred feet (80-100 ft.). The systems and method provide for a five-branch system with sprinklers having a directional spray interleaved between sprinklers having a uniform radial spray at the peak ridge and sprinklers having a uniform radial spray at the eave of the attic space. The systems and methods define a hydraulic demand with a total flow rate of under 175 GPM.

Abstract: Attic fire protection sprinklers for protection of the eave regions of the attic space. The eave sprinkler has a fluid deflector for generating a directional spray with a horizontal throw of up to twenty-eight feet (28 ft.). The deflector includes a base having a leading edge with a flap extending angularly from the leading edge of the base. The flap forms a discharge channel that widens in the radial direction from the sprinkler axis. The flap includes a central canopy portion and a pair of sidewalls disposed about the central canopy portion. An attic fire protection system is provided that includes the eave sprinkler to provide a maximum roof span of protection of up to eighty feet (80 ft.) and a roof slope of protection that ranges from 2½:12 to 6:12.

Abstract: A fire protection sprinkler assembly having a frame that includes a pair of frame arms configured with a geometry that strengthens the frame arms to resist impact, shear and/or torsional loads. The sprinkler assembly can be configured for installation in any one of an upright sprinkler, a pendent sprinkler, horizontal sidewall sprinkler or a recessed sprinkler.
