Various concepts are provided for suppressing a fire condition in an aircraft. In one embodiment, the presence of a fire condition in an aircraft is detected. After such a detection, extinguishing agents can be dispensed and/or certain areas of the aircraft can be depressurized.

A fire extinguishing apparatus of a vehicle is capable of effectively extinguishing a fire by uniformly and directly spraying a fire extinguishing agent in a wide range to a battery cell covered with an external structure in a vehicle. The fire extinguishing apparatus includes a cover, a spray nozzle, a controller, a driving device, and a fire extinguishing agent supplying device.

A dry sprinkler assembly includes a housing, a sprinkler head assembly with a sprinkler head and a trigger assembly, and an actuator assembly. The actuator assembly has a sealing subassembly for sealing the inlet port of the housing and is operatively coupled to the trigger assembly such that the sealing subassembly releases the sealing of the inlet port in response to the trigger assembly releasing its closure at the outlet opening. The sealing subassembly moves in a linear path substantially parallel with the central longitudinal axis of the housing when releasing the sealing of the inlet port wherein the flow of fire suppressant through the inlet port and into the fluid flow passage is substantially unimpeded.

A fire-fighting system includes a base component, a nozzle located remote from the base component, and a locator component mounted to the nozzle. The locator component is communicatively coupleable to the base component, and includes a transceiver configured to wirelessly receive signals from the base component, and a locator beacon including a visually-perceptible output device. The locator component is configured to activate the locator beacon in response to an activation signal received from the base component.

A fire extinguisher assembly is disclosed, providing a connection from a standard fire extinguisher tank through to a housing with dispersion vents. A spray nozzle is secured within the housing for dispersing the fire retardant agent through the dispersion vents, and a connecting means is disclosed, positioned on the housing for securing the extinguisher assembly to a structure. An adapter further comprised of a first end fastened to the spray nozzle and a second end connected to an extinguisher tank is also disclosed to provide the said connection, therefore the fire retardant agent is expelled directly from the extinguisher tank through to the dispersion vents.
