Abstract:
A pre-smoke detector and system for use in early detection of developing fires whereby vapors of marker chemicals generated during the melting and/or smoldering of common household materials are detected before detection by conventional smoke detectors. Vapors resulting from heating and resultant vaporization of substances are detected as well as vapors resulting from their breakdown, decomposition, or pyrolysis during the pre-combustion stage. Conventional smoke detectors focus on particle detection and are most effective after a developing fire has produced smoke. To minimize false alarms caused by common household odors, the pre-smoke detectors focus on detecting medium temperature pyrolysis products using sensor coatings that can be consistent with a  10 -year operational lifetime and multiple orthogonal detection processes. Since virtually all marker chemicals of interest for pre-smoke detection are heavier than air, a system is described that appropriately integrates with smoke detector alarm systems present in most homes.

Claim (Index 1):
A detection system for early detection of fires or potential fires, the detection system comprising:\n an array of microcantilevers on a sensor chip configured to measure a plurality of molecular properties, at least one microcantilever of the array of microcantilevers comprising a different chemical sensitive coating than at least another microcantilever of the array of microcantilevers; and an electronic circuit comprising a controller, the controller configured to:\n drive the array of microcantilevers; and \n detect at least one property of a chemical emitted from a material prior to ignition of the material.
