Abstract: An automatic fire protection sprinkler assembly for fire protection systems that includes a tubular outer housing having an inlet, an outlet opening and an internal shelf proximate the outlet opening. A fluid deflection member is spaced from the outlet opening along a fluid flow path of the assembly. A fluid control assembly is disposed within the outer housing for axial translation from an unactuated state to an actuated state of the sprinkler assembly. The fluid control assembly includes a seal subassembly, a fluid flow tube; and an ejectable support subassembly. The support subassembly includes a projection member. Upon actuation of a thermally responsive trigger, the support subassembly is ejected out the outlet opening such that the projection member comes into contact with the internal shelf of the housing to pivot the support subassembly out of the fluid flow path.

Abstract: The invention is directed to a pressure controller and a method for monitoring and controlling the pressure level in a fire protection piping network maintained under vacuum pressure and for detecting a positive pressure variation in the network. The rate of pressure increase is used to detect the opening of a sprinkler head in the sprinkler piping network.

Abstract: There is described an electronic fire reporting and sprinkling control module to be connected to a control bus of a fire alarm system, and to a flow control valve which controls flow of extinguishing fluid into a sprinkler system. The sprinkler system can be monitored by pressurized air.
