Fire sensing and suppression method and system responsive to optical radiation and mechanical wave energy.

摘要

Described herein is a method and system for sensing explosive fires by the parallel processing of signals derived from both electromagnetic radiation and mechanical wave energy simultaneously emanating from or near the source of these fires. The electromagnetic wave energy and mechanical wave energy are detected by sensing means including an electric or magnetic field transducer (150) in one signal processing channel and thermal (178) and photon (184) detectors in parallel signal processing channels.
