Abstract: An adjustable nozzle assembly includes a receiver having a fluid inlet configured to be fluidly coupled to a fluid source and an internal surface defining a reception chamber fluidly coupled to the fluid inlet, a swivel member disposed in the reception chamber of the receiver, a nozzle coupled to the swivel member, fluidly coupled to the reception chamber, and configured to discharge fluid along a discharge axis, and a restriction member coupled to the receiver such that the swivel member is positioned between the receiver and the restriction member. The swivel member has an external surface including a substantially spherical external surface portion in contact with the internal surface of the receiver. The restriction member has a surface geometry defining a passageway through which the nozzle extends, and the surface geometry limits rotation of the swivel member within the receiver.

Abstract: A fire suppression system includes a delivery system that is configured to receive fire suppressant agent from a reservoir and provide the fire suppressant agent to an area at a flow rate, according to some embodiments. In some embodiments, the delivery system is further configured to provide a first quantity of fire suppressant agent to an area at a first flow rate during a first time interval. In some embodiments, the delivery system is further configured to provide a second quantity of fire suppressant agent to the area at a second flow rate during a second time interval. In some embodiments, the second flow rate is less than the first flow rate. In some embodiments, the first and the second quantity of fire suppressant agent are provided to the area via a nozzle.

Abstract: Fire suppression systems (10) include modules (14x) interconnected with a centralized controller (12). The modules (14x) are configured, assembled and sealed for system operation in harsh environments. Modules of the system include a printed circuit board (PCB, 32, 132), a microprocessor (34), and an operative component (36) assembled within a housing (30, 130). A gasket member (38) is disposed about the component to form a seal about the component. Operative components may include fire detection elements (14x, 50) or an LCD screen (36, 236). Modules of the system can include an encapsulant compound for filling a void between the housing inner surface and the printed circuit board. Modules of the system can include a sealed chamber with a port to interface a computer device. A power module of the system includes a sealed housing with connectors positioned to protect against moisture and debris and an isolating switch to permit maintenance of the system.
