Fire protection systems and methods for ceiling-only high-piled storage protection. The systems include a plurality of fluid distribution devices disposed beneath a ceiling and above a high-piled storage commodity having a nominal storage height ranging from a nominal 20 ft. to a maximum nominal storage height of 55 ft. and means for quenching a fire in the storage commodity. The stored commodity to be protected may include exposed expanded plastics. The fluid distribution devices include a frame body having an inlet, an outlet, a sealing assembly, and an electronically operated releasing mechanism supporting the sealing assembly in the outlet.

Various aspects of the invention are directed to a triggering device for a quickly triggering extinguishing system for explosion suppression. In some embodiments of the present disclosure, the triggering device may include a pawl body having a pawl flank, a catch, at least one electromagnet to transmit an electromagnetic field, and a sliding pin. The sliding pin triggers an extinguishing system for explosion suppression by movement from a blocking position into a release position. In the blocking position, the sliding pin is pushed against the pawl flank of the pawl body by means of the catch and is held in the blocking position by said pawl flank. The pawl body releases the engagement of the catch and the pawl flank, and thereby releases the sliding pin, in response to the at least one electromagnet exerting the electromagnetic field on the pawl body.

A fire sprinkler head (12) has a valve (42) with an X-brace latch (54), and includes a flexible conduit (14). A sprinkler nozzle (16) is secured to a first end of the flexible conduit (14). The sprinkler nozzle (16) includes a first fitting (28), a sprinkler orifice (20) and fusible element (22). A second fitting (40) is secured to the second end of the flexible conduit (14) and includes the valve (42). The valve (42) has a valve element (44) which is moveable from a latched position to an unlatched position. A flexible link (56) extends from the sprinkler nozzle (16) to the X-brace valve latch (54). Breaking of the fusible element (22) releases the flexible link (56) to move from the latched position to the unlatched position, releasing the valve (42) for flow there-through.

The present invention discloses an automatic security cylinder system comprising one or more cylinder which are provided with cylinder valves, the cylinder valves are connected with an electronic control device which can realize signal transmission with the controller, the electronic control device is opened by the controller, so that the gas in the upper cavity is discharged outward, the pressure of the upper cavity decreases, and the piston moves upward, so as to realize the automatic opening of the valve port, the medium in the cylinder is released outward through the nozzle, the electronic control device is closed by the controller, and the piston moves down and reset, so as to realize the automatic closing of the valve port and stop the nozzle releasing the medium. The present invention has the functions of automatic starting and resetting, thereby realizing multiple medium releasing. The present invention also discloses an automatic control method of an automatic security cylinder system.

A fire suppression system includes a feed port and a channel to couple the feed port to an actuation chamber. A solenoid valve controllably blocks a connection between the feed port and the channel. Pressure from the feed port builds up in the actuation chamber based on the solenoid valve unblocking the connection. A piston is in communication with the actuation chamber. The system also includes an inlet port closed off by a disc. The piston travels through the inlet port and burst the disc based on the pressure in the actuation chamber. An outlet port is coupled to the inlet port.

An actuator assembly for use in fire suppression systems for use in vehicle and industrial fire protection systems. The actuator assembly engages a cartridge of pressurized gas and releases the gas contained therein with a puncturing assembly. The actuator assembly includes a receptacle that controls the manner in which the actuator assembly and cartridge engage one another. The actuator assembly is configured for electrical and pneumatic actuation for rupturing the seal of the cartridge of pressurized gas. The actuator assembly has a housing that includes at least one inlet port that is coupled to a pressurized gas source, which is formed between a first chamber for electrical components sealed from the operative environment of the actuator assembly and a second chambers for the puncturing assembly. The actuator assembly allows for serial interconnection of multiple actuator assemblies for operation by a single source of pressurized gas.
