optical radiation and mechanical wave energy in response to the fire detection and fire extinguishing method and system

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 radiation or thermal energy is detected by an electromagnetic wave energy detector or a thermal detector (1 to 6) and the mechanical wave energy is detected by a pressure transducer (1 to 8). This diverse-stimuli sensing capability enhances force alarm immunity of the system.
