Abstract
A fire detection system for an enclosed area comprises: at least one infrared (IR) imager for generating infrared images of at least a portion of the enclosed area, for determining from the images that a fire is perceived present in the enclosed area, and for generating a first signal indicative of the perceived presence of fire; at least one fire detector for monitoring at least a portion of the enclosed area, the fire detector comprising at least one fire byproduct chemical sensor for generating at least one second signal representative of the presence of at least one fire byproduct chemical in the enclosed area; and a controller governed by the first and second signals to confirm that a fire is present in the enclosed area. In one embodiment, the enclosed area is divided into a plurality of detection zones with at least one fire detector disposed at each detection zone. In this embodiment, the controller includes a first controller governed by the second signals for generating a third signal indicative of the presence of fire in the corresponding detection zone; and a second controller governed by the first and third signals to confirm that a fire is present in at least one detection zone of the enclosed area.
