1. A fire extinguishing system, comprising:
- a fire extinguisher having an output nozzle, a breakable valve release, and a container, the output nozzle being separate and distinct from the container, the container coupled to the output nozzle via the breakable valve release that is coupled between the container and the output nozzle, and the container including an extinguishing agent; and
an automatic activation apparatus coupled to said fire extinguisher proximate to the breakable valve release, said automatic activation apparatus operable to (i) monitor local temperature, and (ii) induce breakage of the breakable valve release based on the monitored local temperature to thereby release at least a portion of the extinguishing agent,wherein the container is a cylinder container having a top end, andwherein the breakable valve release is coupled to the top end of the cylinder container.

Abstract
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.

10. A fire detection apparatus, comprising:
-
a temperature sensor; a heat collector, the heat collector being thermally coupled the temperature sensor so as to enhance temperature responsiveness of the temperature sensor, the heat collector being a distinct component from the temperature sensor; an extinguishing agent; an automatic activation apparatus; and a controller operatively connected to the temperature sensor and the automatic activation apparatus, the controller including at least; means for reading an electrical characteristic from the temperature sensor; means for determining a sensor value based on the electrical characteristic; means for determining whether the sensor value is greater than a predetermined trip point; and means for producing a control signal by the automatic activation apparatus to initiate release of the extinguishing agent by the fire extinguisher if the means for determining determines that the sensor value is greater than the predetermined trip point.
