Researchers have found significant benefits of multi-sensor detection in reducing false triggering. Appreciable interest has been expressed in using carbon monoxide (CO) or carbon dioxide (CO2) gas sensors in combination with smoke sensors. The present study has been carried out to determine the correlation and inter-dependence between two different fire signatures like CO–OD (optical density), CO–CO2, CO2–OD. The signatures have been investigated using experimental measurements of a fire inside a closed compartment measuring 7 x 7 x 4.2 m. A range of fuels are used, and both smouldering and flaming combustion are examined. Attempts have been made to examine whether correlation coefficients between two signatures can form a basis of detection and be exploited as one of the components in multi- criteria fire detection algorithm. The CO/CO2 ratio as a criterion for detector operation has also been examined and discussed in the light of existing literature and codal provisions. 6 Fire Technology 50 ARTICULO Kumar, Rajiv 28229 Singh, M.P. 55558 189682 189682 0 0 0 0 257501 BAAB BAAB 2026-03-06 200061922 0 200061922 2026-03-06 00:19:50 2026-03-06 ARTICULO
