- Abstract
- [ABSTRACT IN ENGLISH] Infrared type fire detectors detect resonance CO2 radiation given off by flame and combustion. By detecting infrared rays in several wave lengths, fire combustion temperature, combustion area, and the presence of fire were detected. From this information, a new fire detection formula to judge fire presence was devised and tests conducted. It is possible to detect changes in fire from the CO2 ratio.
