The present invention discloses a fire extinguishing system for a battery pack, including a detection control apparatus, a fire suppression apparatus, and a hydrant water extinguishing apparatus. The detection control apparatus is disposed inside or outside a battery pack. The fire suppression apparatus and the hydrant water extinguishing apparatus are disposed outside the battery pack. The detection control apparatus is connected to the fire suppression apparatus. The hydrant water extinguishing apparatus is connected to the fire suppression apparatus. Beneficial effects: It is ensured that initial fire can be suppressed and later reignition can be resolved, so that fire extinguishing is adequate. Fire is directly extinguished at a core position inside the battery pack. An exhaust filter device gains valuable time after initial fire extinguishing.

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 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 system for providing fire suppression includes multiple capsules and a suppression system. The capsules may be positioned proximate a hazard. Each capsule includes a wall configured to rupture in response to a particular temperature or in response to fluidic contact. The capsules are each configured to store a suppressant agent within the wall of the capsule. The suppression system is configured to discharge a fluid to the hazard in response to a thermal condition at the hazard. The fluid is configured to react with the suppressant agent to provide fire suppression to the hazard.
