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.

A valve body (5) for a cartridge-operated fire extinguisher includes a first socket (51) configured to have an end of a cartridge (11) filled with propellant installed therein; and a latch (57) movable relative to the first socket (51) between a first position and a second position; in the first position the latch (57) is configured to permit an end of a cartridge (11) filled with propellant to be installed within and removed from the first socket (51); and in the second position the latch (57) is configured to engage with an end of a cartridge (11) installed within the first socket (51) to thereby lock and retain the end of the cartridge (11) within the first socket (51).

A cartridge-operated fire extinguisher 100 that includes a valve body 104 and a cylinder 102. The valve body (104) includes three fixing points 300, 302, 304 each including an aperture 300a, 302a, 304a with a fixing point axis A, B, C. The third fixing point axis C is oriented at an angle relative to the first fixing point axis A and the second fixing point axis B. The cylinder includes three bolts 210, 212, 214 for fixing the valve body to the cylinder. Each bolt includes a shaft 210a, 212a, 214a with a shaft axis X, Y, Z. The first shaft axis X and the second shaft axis Y are parallel, and the third shaft axis Z is oriented at an angle relative to the first shaft axis X and the second shaft axis Y.

A hose connector 106 for a cartridge-operated fire extinguisher 100, the hose connector 106 including: a valve body connection tube 330 for connecting the hose connector 106 to a valve body of the fire extinguisher 100, the valve body connection tube 330 is non-threaded; a hose connection tube 332 for connecting a hose to the hose connector 106; and a fixing plate 334 for fixing the hose connector 106 to the valve body of the fire extinguisher 100.

An aiming assembly including a housing and a light source. The housing is configured to be coupled to a nozzle and includes at least one mounting feature configured to retain the housing in a desired position relative to the nozzle. The light source provided at least partially within the housing and configured to selectively generate a conical light beam, and generate a light image.

A fire suppression system includes at least one spray nozzle for expelling a fire suppression agent into a space; a first container at least partially filled with a first fire suppression agent. The first fire suppression agent within the first container has a first pressure. A conduit extends from the first container to at least one spray nozzle. A second container is at least partially filled with a second fire suppression agent and is arranged in fluid communication with the conduit. The second fire suppression agent within the second container has a second pressure less than the first pressure. A mixture of the first fire suppression agent and the second fire suppression agent is movable through the conduit to the at least one spray nozzle via the first pressure.

A portable fire suppression device includes a cylinder, and a handle assembly. The cylinder is configured to store and discharge a fire suppressant agent. The handle assembly includes a handle and a resilient bumper. The handle includes a grasping portion for grasping with a user's hand and a connection portion. The connection portion defines a gap configured to receive and attach to a lug of the cylinder. The handle includes a free end located opposite the connection portion. The resilient bumper is positioned within an opening of the lug. The resilient bumper is positioned between the handle and the lug of the cylinder and is configured to absorb vibration and limit movement of the free end relative to the cylinder.
