A residential or commercial sprinkler system is provided wherein the sprinkler heads and piping distribution network are provided with a relatively low pressure fire suppressant liquid in place of pneumatic pressure, which is typical, and control valve keeps fire suppressant supply pressure from entering the discharge sprinkler system at design discharge pressure until a fire detection system detects a fire condition. Upon the detection of a fire condition, a control valve is opened to provide the sprinkler heads and piping distribution network with a fully pressurized supply of fire suppressant. Also in the case of electric control power loss the system will operate from loss of outlet supervised pressure releasing sprinkler liquid suppressant to the discharge system of closed fused sprinklers.

A sprinkler assembly includes a body defining an inlet, an outlet, and a fluid passage extending along a longitudinal axis between the inlet and the outlet. A guide pin aperture is defined by at least one of the body or a bushing coupled to the body. The sprinkler assembly further includes a deflector slidably coupled to the body. The deflector includes a deflector body coupled to a guide pin. The guide pin includes a shaft portion extending through the guide pin aperture and a shoulder that is wider than the shaft portion and configured to engage at least one of the body or the bushing to limit movement of the deflector body away from the body.

A horizontal sidewall sprinkler is provided which includes a sprinkler body having an inlet passage for supply of a fluid and an outlet, the outlet being closed by a sealing assembly prior to actuation of the sprinkler. The sprinkler further includes a sleeve body secured to the sprinkler body and a yoke substantially spanning a width of the sleeve body, the yoke urging a load screw against a surface of the sealing assembly facing an occupancy, and being held in place prior to actuation of the sprinkler by two levers that are joined by a soldered link. A slide plate is located near an inner wall of the sprinkler body facing the occupancy prior to actuation of the sprinkler. According to one example embodiment, a frame or two guide pins are provided for bearing and supporting a deflector. The deflector is positioned between the load screw and the sealing assembly thereby obstructing a flow of fluid from the outlet upon actuation of the sprinkler. A spring is provided in the sprinkler body, between the inner wall of the sprinkler body and pressing (1) the slide plate and (2) the frame or the two guide pins away from the inner wall. Upon actuation of the sprinkler, the levers, the yoke and the load screw are forced out of and away from the sprinkler by the force of the fluid; the spring forces the slide plate outward from the inner wall; and the force of the fluid moves the deflector away from the slide plate to a position for delivery of the fluid to the protected area.

A device for suppressing fire inside a container includes a support structure configured to be mounted inside a vehicle at a position associated with at least one location configured to receive a container. The device further includes a deployment structure coupled to the support structure and a penetrator assembly coupled to the deployment structure. The penetrator assembly includes a nozzle having a tip configured to pierce a container and an actuator associated with the nozzle. The actuator is configured to extend the tip of the nozzle such that it pierces a container. The support structure and the deployment structure are configured such that the penetrator assembly is movable in at least one plane with respect to the support structure, and the penetrator assembly is configured to receive fire suppressant and direct the fire suppressant into the container.

A water-powered residential fire suppression and alarm system is provided. The system comprises a sprinkler head, a water-powered alarm, a fire-resistant transfer line assembly, and a housing assembly. The sprinkler activates upon excessive heat. The transfer line assembly provides an unclosable channel connecting an existing residential water fixture with the sprinkler head. The transfer line assembly includes a fire-resistant transfer line connected to a multi-port coupling which connects to the existing water fixture. The transfer line assembly also provides water to the alarm. The housing assembly has a housing with a vertical span of about 3-12 inches. The sprinkler head and alarm are mounted to the housing assembly and the transfer line assembly is connected to the housing assembly. When water is provided to the coupling and the sprinkler head activates, water flows through the transfer line, activating the alarm.

A sprinkler assembly includes a body, a support, which extends from the body, and a closure device that releasably closes the discharge opening of the body. The sprinkler assembly further includes a trigger that releasably holds the closure device at the discharge opening. The support is adapted to allow the fluid flowing from the discharge opening, when the closure device is released, to pass through the support substantially unimpeded by the support and, further, is adapted to reshape the flow of fluid as it flows through the support.
