Abstract
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. This diverse-stimuli sensing capability enhances the false alarm immunity of the system.
