Abstract: Fire protection systems and methods provide for the protection of horizontal concealed interstitial spaces of either a solid wood joist, open bar joist or open truss construction system. The systems and methods provide and locate fire protection sprinklers to define localized heat detection areas that are over 1000 sq. ft., at least 2000 sq. ft., over 2000 sq. ft. and/or otherwise unconfined by draft curtains or other barriers.

Abstract: System and methods to provide ceiling-only suppression fire protection of up to fifty feet (50 ft.) of rack storage of cartoned unexpanded plastic commodities and less hazardous commodities, such as for example, Class 1, Class 2, Class 3, Class 4 and/or combinations thereof beneath a ceiling having a maximum ceiling height up to fifty-five feet (55 ft.). The systems and methods provide for hydraulic and system parameters that include a hydraulic design area based upon five to no more than twelve hydraulically most remote sprinklers spaced at a preferred sprinkler-to-sprinkler spacing of eight to ten feet (8-10 ft.) coupled to two to four branch lines tied to a common cross main supply pipe of firefighting fluid.

Abstract: Sprinkler guards to protect fire protection sprinklers in their installed and operative positions. A fire protection sprinkler guard includes a structure with a hinged arrangement to flexibly receive a fire protection sprinkler. A latch connection operates in combination with the hinge of the guard to form a rigid cage structure to shield and protect the sprinkler.

Abstract: A dry fire protection sprinkler assembly. The sprinkler assembly includes an elongate tubular outer housing having a first end and a second end opposite the first end. The second end of the housing defines a fluid discharge end of the sprinkler assembly having an outlet opening. A fluid deflection member is affixed to the housing at a preferably fixed distance from the outlet opening. The sprinkler assembly and the fluid deflection member define an unencumbered fluid flow path for a column of fluid discharge from the outlet opening. The fluid deflection member includes at least one tab to act on the unencumbered column of fluid discharge.

Abstract: A device and method of protecting and installing a fire protection sprinkler. The protective device is embodied as a tubular cap that axially receives the sprinkler. The protection and installation device includes an internal gripping portion for engaging the sprinkler. The protection and installation device includes a wall that maintains its geometry before receiving the sprinkler the same after receiving the fire protection sprinkler. Moreover, the protective installation device maintains its geometry constant to sufficiently torque the sprinkler into a fitting for installation.

Abstract: A device for protecting and installing a fire protection sprinkler. The protective device is embodied as a tubular cap that axially receives the sprinkler. The protection and installation device includes a wall with a stiffening element to facilitate the strength and rigidity of the device so that it can sufficiently transfer a torque to install the protected sprinkler.

Abstract: A sprinkler assembly includes a body, a support, which extends from the body, and a closure device that releasably closes the discharge opening of the body. The sprinkler assembly further includes a trigger that releasably holds the closure device at the discharge opening. The support is adapted to allow the fluid flowing from the discharge opening, when the closure device is released, to pass through the support substantially unimpeded by the support and, further, is adapted to reshape the flow of fluid as it flows through the support.

Abstract: Fire protection sprinkler assemblies and methods of use in corrosive environments. The sprinkler assemblies include a corrosion resistant sprinkler frame made of a gradient material. The gradient material includes a polymeric layer interlocked about a corrosion-prone core in order to protect the frame structure from a corrosive environment. The interlock between the core and the protective polymer layers are defined by ionic bonding between the core and the outer polymer layer.
