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.

Abstract: A sprinkler head cover including an end wall and a side wall extending from and around the end wall to form a cavity therebetween. The cavity is sized for receiving a deflector and arms of a sprinkler head. The side wall is adapted for engaging the sprinkler head to thereby releasably mount the cover to the sprinkler head. The sidewall includes a tear-away strip to facilitate removal of the cover from the sprinkler head.
