A fire detection device and method therefor are able to provide automatic activation so as to extinguish a fire. The fire detection can be rapid and temperature-based. In one embodiment, a heat collector can be provided to enhance thermal responsiveness. Activation of the fire detection device can be electrically induced to release an extinguishing agent at the fire. The activation can be protected such that it is durable and unaffected by vibrations.

A fire extinguisher includes a liquid fire extinguishing media, and first and second gases inside of a storage vessel at an operating pressure, and a discharge tube extending between a control valve and the fire extinguishing media. At least a portion of the first gas is dissolved in the fire extinguishing media. The control valve can be operated to control discharge of the fire extinguishing media via the discharge tube whereupon at least a portion of the second gas enters a flow of the fire extinguishing media via one or more holes in the discharge tube forming bubbles of the second gas in the flow of the fire extinguishing media. The fire extinguishing media exiting the control valve can pass through a nozzle which can causing first and second portions of the fire extinguishing media to collide forming a plume mist of the fire extinguishing media.
