A fire retarding canister has a housing with aerosol exit ports. A cooling material is supported within the housing above the exit ports. A combustion chamber within the housing is above the cooling material. An aerosol forming composition is supported within the housing above the combustion chamber. An ignition mix extends into the aerosol forming composition for igniting the aerosol forming composition. A firing pin is disposed within the housing and is held in place by a temperature sensitive material. In one example, the temperature sensitive material releases the firing pin after a desired temperature is released.

Ignition unit for aerosol fire-retarding delivery device
An ignition unit for a fire extinguishing assembly has an ignition unit housing with a firing pin disposed within the housing. A spring is coupled to the firing pin, and a restraining device holds the pin in place in the housing. A formed eutectic holds the restraining device in place such that when the eutectic deforms, the firing pin is released and moved by the spring in a desired direction.
A fire extinguishing assembly includes an ignition unit and an aerosol generating unit. The ignition unit in one embodiment comprises a spring loaded piston that is held under spring tension by a formed eutectic, which deforms at a predetermined temperature. When such temperature is reached, the piston is released, and strikes a primer to ignite a desired pyrotechnic in the aerosol generating unit. In one embodiment, the piston strikes a primer, which ignites an ignition mix, which further ignites the pyrotechnic. The ignition mix may be formed of the same material as the pyrotechnic. The ignition unit may be releasably engaged with the aerosol generating unit that contains the pyrotechnic. In one embodiment, it is formed with threads for mating with threads on the canister.

Tunnel fire protection system for isolating and suppressing fires in a tunnel includes a fire detecting arrangement arranged in the tunnel for detecting a fire, curtain assemblies spaced apart from one another in an axial direction of the tunnel to partition it into zones and a control unit coupled to the fire detecting arrangement and the curtain assemblies for directing the release of curtains from the curtain assemblies based on the detection of a fire. In this manner, a tunnel fire can be isolated in a zone between a pair of barriers formed by the curtains upon their release. To suppress the fire, fire extinguisher units are arranged on the tunnel walls, with at least one in each zone, and those in the zone in which the fire is detected are activated by the control unit. The fire extinguisher units may be aerosol-type fire extinguishers.
A62C 3/02 - Fire prevention, containment or extinguishing specially adapted for particular objects or places for area conflagrations, e.g. forest fires, subterranean fires
Manually activated, portable aerosol fire extinguisher includes a casing having discharge ports, an arrangement for generating fire suppression agent which is discharged through the discharge ports, and a manual activation system which enables manual activation of the generating arrangement at a safe location a distance from the fire. The activation system includes a firing pin which causes ignition of igniter material upon contact therewith (resulting in generation of the fire suppression agent), a handle which normally prevents the firing pin from contacting the igniter material and a manually releasable pull pin arranged to maintain the handle in a position preventing the firing pin from contacting the igniter material. Upon release of the pull pin, the handle is urged out or this position with the results that the firing pin contacts the igniter material, thereby causing generation of the fire suppression agent.

Manually activated, portable aerosol fire extinguisher includes a casing having opposed end walls and discharge ports in each end wall, an arrangement for. generating fire suppression agent to be discharged through the discharge ports, and an activation system which enables manual activation of the generating arrangement at a safe location a distance from a fire. The activation system includes a firing pin which causes ignition of igniter material upon contact with a primer thereof, a delay column arranged between the primer and igniter material to delay ignition of the igniter material, a safety lever which normally prevents the firing pin from contacting the primer and a manually releasable pull pin which maintains the safety lever in a position preventing the firing pin from contacting the primer. Upon release of the pull pin, the firing pin contacts the primer causing generation of the fire suppression agent.
