  • Title: [Research on early fire detection with CO-CO2 FTIR-spectroscopy].
    Author: Du JH, Zhang RC, Huang XY, Gong X, Zhang XH.
    Journal: Guang Pu Xue Yu Guang Pu Fen Xi; 2007 May; 27(5):899-903. PubMed ID: 17655099.
    Abstract:
    A new fire detection method is put forward based on the theory of FTIR spectroscopy through analyzing all kinds of detection methods, in which CO and CO2 are chosen as early fire detection objects, and an early fire experiment system has been set up. The concentration characters of CO and CO2 were obtained through early fire experiments including real alarm sources and nuisance alarm sources. In real alarm sources there are abundant CO and CO2 which change regularly. In nuisance alarm sources there is almost no CO. So it's feasible to reduce the false alarms and increase the sensitivity of early fire detectors through analyzing the concentration characters of CO and CO2.
