A method and device for protecting and installing a fire protection sprinkler assembly having a thermally responsive trigger. The method includes shielding and torqueing a fire protection sprinkler with a protective device having a torque assist portion. The protective device includes a first and second member strapped about the sprinkler assembly. Each of the members of the protective device has a first lateral end and a second lateral end disposed about the thermally responsive trigger. At least one of members has a concave segment and a convex segment formed between the first lateral end and the second lateral end. The convex and concave segments define therebetween an external torque assist surface of the protective device that can be used to manually torque and install the sprinkler assembly.

Fire protection systems and methods having piping interconnections for connecting a fire protection device to a fluid source. The piping interconnections include a branch connector connected to a pipe header. The branch connector includes a tubular member and an internal annular seal member housed in an internal gasket chamber of the tubular member. The tubular member includes an internal stepless surface between a terminal end of the tubular member and the internal gasket chamber.

A helipad fire suppression system includes a helipad having an outer boundary that defines an impervious deck area for at least one of landing or storing one or more helicopters, with at least a portion of the impervious deck area being designated a fire suppression target area. The system includes a nozzle assembly having a spray-type nozzle for spraying a fire suppression fluid in a radial pattern. The nozzle assembly can include a nozzle enclosure for enclosing the spray-type nozzle and can be configured for installation in a surface made of an impervious material. The nozzle assembly is disposed in an interior portion of the impervious deck area so as to provide the fire suppression fluid to the fire suppression target area.

A proportioner having a body portion that defines a foam passage and a fluid passage. The proportioner also includes a restrictor assembly having a restrictor disk and an orifice plate having an opening for receiving the restrictor disk. The proportioner can further include a rod member connected to the restrictor disk and a clapper assembly connected to the rod member via a sliding interface. The clapper assembly can be configured to control a flow of the foam concentrate through the foam passage in proportion to a flow of the fire protection fluid through the fluid passage by moving the rod member to vary the distance between the restrictor disk and the orifice plate. The sliding interface can be disposed between a first guide and a second guide, and at least a portion of the restrictor disk is disposed in the opening.

Proportioner for a fire protection system

Fire protection systems and methods having piping interconnections for connecting afire protection device to a fluid source. The piping interconnections include a branch connector connected to a pipe header. The branch connector includes a tubular member and an internal annular seal member housed in an internal gasket chamber of the tubular member. The tubular member includes an internal stepless surface between a terminal end of the tubular member and the internal gasket chamber.

A proportioner having a body portion that defines a fluid passage for transporting a fire protection fluid and a foam passage for transporting a foam concentrate. The foam concentrate mixes with the fire protection fluid to form a fire protection solution. The proportioner also includes a restrictor assembly having a restrictor disk and an orifice plate. The orifice plate has an opening for receiving the restrictor disk. The restrictor disk and opening are configured to form an annulus between an outer surface of the restrictor disk and an inner surface of the opening when at least a portion of the restrictor disk is disposed within the opening and the restrictor disk is spaced from the orifice plate. The restrictor assembly is configured to maintain the annulus for a full travel range of the restrictor disk.

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.
