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.
Claims20
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 activation element;
- and
- a controller operatively connected to the temperature sensor and the activation element, the controller being configured to at least:
- (i) monitor a current temperature indication using the temperature sensor and the heat collector, (ii) determine whether the current temperature indication indicates a current temperature greater than a predetermined trip point, and (iii) produce a control signal to direct the activation element to initiate release of the extinguishing agent if it is determined that the current temperature indication indicates the current temperature is greater than the predetermined trip point.
