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.
Claims4
A method for fire detection using temperature sensing in an area to be monitored for a fire, said method comprising:
- providing at least one fire extinguisher proximate to the area to be monitored for a fire, the fire extinguisher including an extinguishing agent, a temperature sensor and an automatic activation apparatus, the automatic activation apparatus being operatively connected to the temperature sensor;
- obtaining a plurality of successive measurements of a sensor electrical characteristic from the temperature sensor;
- processing the successive measurements to obtain a stabilized sensor electrical characteristic;
- determining if the stabilized sensor electrical characteristic is greater than a predetermined value;
- producing a control signal by or for the automatic activation apparatus to initiate release of the extinguishing agent in the area by the fire extinguisher if said determining concludes that the stabilized sensor electrical characteristic is greater than the predetermined value;
- and
- causing release of the extinguishing agent in the area based on the control signal,
- wherein the fire extinguisher includes a container that contains the extinguishing agent, the automatic activation apparatus is coupled to the container, and
- wherein the container has an upper portion, and the automatic activation apparatus and the temperature sensor are physically coupled to the upper portion of the container.
