Abstract: 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.

Abstract: The invention relates to a computer program product for configuration of a control center, in particular a fire alarm and/or extinguishing control center, and to an associated method. The computer program product comprises: a hardware configuration component for configuration of hardware components such as modules and/or front panel components of the control center, a logic configuration component for configuration of a functional logic of the control center, wherein the logic configuration component is designed to provide functional components. The functional components are decoupled from the hardware of the control center and embodied in such a way that reversible assignment of functional component to hardware component is made possible.

Abstract: An automatic dry fire protection sprinkler assembly and method of operation. The sprinkler assembly includes an elongate tubular outer housing having a fluid discharge end with an outlet opening, an internal channel and a contact surface proximate the outlet opening. A fluid deflection member is coupled to the housing at a preferably fixed distance from the outlet opening. An internal fluid control assembly includes an ejectable member that is ejected out the outlet opening and displaced out of the fluid flow path between the housing and the fluid deflection member. Upon sprinkler actuation, the fluid control assembly engages the internal channel to axially guide the fluid control assembly and prevent rotation of the fluid control assembly about the sprinkler axis. A surface contact between the ejectable member and the internal shelf causes the ejectable member to pivot clear of the sprinkler housing and the fluid deflection member.

Abstract: 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.
