Cover of a fluid control valve assembly for fire protection systems

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.

Systems and methods for fire protection of horizontal interstitial spaces with expanded localized heat detection areas

A device and method for protecting and installing a fire protection sprinkler. The protective and installation device has two discrete protective members coupled to one another about the sprinkler by a releasable locking arrangement defined by a connection between the two discrete protective members. At least one of the members includes a torque assist portion for applying torque to the fire protection sprinkler and each of the members includes a deflector protection portion.

Protection and installation device for fire protection sprinklers

Differential-type dry pipe valves for fire protection systems are provided. The valve includes a body with a clapper assembly disposed in an internal passage of the valve body between an inlet and an outlet. The clapper assembly is movable between a closed position and an open position to respectively prevent and permit fluid flow through the passage from the inlet to the outlet. With the clapper assembly in the open position, an internal mechanism is positioned to stop the clapper moving to the closed position. The valve includes a resetting assembly having a knob exterior to the body. Translation of the knob toward the outlet moves the internal mechanism which permits the clapper assembly to move to the closed position.

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.

Fluid control valve assemblies for use in fire protection sprinkler systems to control the flow of firefighting fluid to the system sprinklers. The assemblies include a pressure-operated fluid control valve having an internal fluid chamber in which fluid contained therein acts on an internal diaphragm to control the flow of fluid from an inlet to an outlet of the valve. An environment-responsive control device in fluid communication with the internal fluid chamber along a first fluid communication line controls the flow of fluid out of the fluid chamber to initiate actuation of the valve. A fluid-flow latch in fluid communication with the outlet of the valve along a second fluid communication line subsequently controls the simultaneous flow of fluid out of the fluid chamber and the actuation of the valve.

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.

Automatic fire sprinklers, systems and methods for suppression fire protection of high hazard commodities including commodities stored in rack arrangements beneath ceilings of up to fifty-five feet in height

A fire protection containment unit for protection of an intermediate bulk container (IBC) having an internal flame and drain barrier disposed above a basin portion of the containment unit. The barrier includes pans having an impact surface that is angled to drain toward a central grid of the barrier to direct escaped liquid from the IBC into the basin portion of the containment unit. The basin portion includes a base surface on an incline to define a pooling region of the containment unit to collect escaped liquid from the IBC. The containment unit includes containment walls which define various configurations of the containment unit including an open configuration, partially open configuration, a completely contained configuration and a packaged configuration.
