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 sprinkler system includes a fitting, at least one tube, at least one fluid distribution device, and an actuator. The fitting connects with at least one pipe, defines an opening, and includes a seal. The seal has a closed state in which the seal seals the opening and an open state in which the seal does not seal the opening to allow fluid flow from the at least one pipe through the opening. The at least one tube connects with the fitting on an opposite side of the seal from the at least one pipe. The fluid distribution device is connected with the at least one tube. The actuator receives a detection signal indicative of a trigger condition and causes the seal to change from the closed state to the open state to allow the fluid flow through the opening responsive to receiving the detection signal.

A valve assembly includes a valve and a valve sensor. The valve includes a solenoid including a core and a coil, and a valve body having a closed state in which fluid is prevented from flowing through the valve body and an open state in which fluid flows through the valve body. The valve sensor detects at least one of the valve body and the coil and causes an alarm to be triggered responsive to not detecting the at least one of the valve body and the coil in a respective target position of the at least one of the valve body and the coil.

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 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.

A manual activation system includes a bracket rotatable about a first axis between a first configuration and a second configuration and a pulley movable between an inactive position and an active position. The pulley is mounted to the bracket and is rotatable about a second axis. A tension member is wrapped about the pulley and has a tensile force acting on the pulley. An activation member is configured to cooperate with the bracket to selectively oppose the tensile force.

A communication system includes a first radio frequency identification (RFID) device coupled to a sensor that monitors a fire condition and a second RFID device. The first RFID device includes at least one first antenna that receives a fire detection signal from the sensor, and a processing circuit that causes the at least one first antenna to transmit a radio frequency (RF) signal corresponding to the fire detection signal through an internal volume of a pipe coupled to a fluid source. The second RFID device includes at least one second antenna that receives the RF signal through the internal volume of the pipe. The second RFID device controls operation of a fluid distribution device responsive to receiving the indication of the fire detection signal.
