Temperature-based fire detection
First Claim
Patent Images
1. A method for fire detection using a temperature sensor provided in an area to be monitored for a fire, said method comprising:
- securing at least one fire extinguisher to a structure proximate to the area to be monitored for a fire, the fire extinguisher including an extinguishing agent and an automatic activation apparatus, the automatic activation apparatus being operatively connected to the temperature sensor;
reading an applied voltage provided to the temperature sensor, the temperature sensor being thermally coupled to a heat collector so as to enhance temperature responsiveness of the temperature sensor;
reading a sensor voltage from the temperature sensor;
determining a sensor resistance based on the sensor voltage and the applied voltage;
determining whether the sensor resistance is greater than a predetermined trip point; and
producing a control signal by the automatic activation apparatus to initiate release of the extinguishing agent in the area by the fire extinguisher if said determining determines that the sensor resistance is greater than the predetermined trip point.

Abstract
A fire detection device and method therefore 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.
