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.

A trigger device is disclosed including a body including first and second ends. The first end is configured to be operatively coupled to a tensioned line of a mechanical fire detection line. The trigger device includes a piston configured to be slidably disposed along a length of the body, the piston configured to be operatively coupled to the tensioned line. The trigger device includes slots provided on the body configured to receive actuation cables. The trigger device further includes a coupling element configured to be coupled to the piston and configured to slidably move responsive to movement of the piston. The coupling element includes a free end configured to move through the slots to selectively couple with the actuation cable. responsive to the piston moving towards the second end of the body, the coupling element moves out of the slots to decouple with the actuation cable.

A sprinkler includes a frame, a deflector member, a sealing assembly, and a releasing mechanism for a controlled actuation. The releasing mechanism includes a hook member, a strut member, a load member, a link member, and an actuator. The link member surrounds or frames the strut and hook members and holds the members in a static relationship of an unactuated configuration. A preferred link member includes a single central slot through which each of the hook member and the strut member extend. The actuator is arranged with respect to the link member to separate the hook and strut members and break the link member upon operation of the actuator.

A fire extinguisher valve for controlling a flow of a fire extinguishing agent in a fire extinguishing system comprises a valve body; a manual lever, which is manually movable between an open position, in which a fire extinguishing agent discharge path through the valve body is established, and a closed position, in which the fire extinguishing agent discharge path through the valve body is closed; and a mechanical actuator, which is mounted to and supported by the valve body. The mechanical actuator comprises an actuation element for acting upon the manual lever for moving the manual lever from its closed position to its open position; an elastic element for moving the actuation element, and a trigger mechanism for holding the actuation element in a preloaded position, in which the elastic element is preloaded, and for releasing the actuation element, when the mechanical actuator is activated.

A fire protection system includes a pipe system in fluid communication with a water source. A local processing unit is operatively coupled to a radio frequency identification (RFID) tag reader antenna. Sensors monitoring a sensor area for the presence of a fire are in electrical communication with the local processing unit. Fluid distribution devices in fluid communication with the pipe system are configured to deliver water from the water source to the sensor area. An RFID tag apparatus is coupled to one of the fluid distribution devices and includes an RFID tag antenna positioned within the pipe system and is configured to transmit and receive radio frequency (RF) signals to and from the RFID reader antenna and local processing unit, through the pipe system.
