Analysis of the Response Characteristics of Smoke and Carbon Monoxide in Non-Fire Conditions

Abstract

This study confirms the applicability of cross-detection by analyzing the response characteristics of smoke and carbon monoxide detectors, to reduce non-firm alarms. Based on the results of previous studies, various scenarios reflecting non-fire conditions in Korea were selected, to conduct experiments to confirm the change in carbon monoxide concentration and the response of smoke detectors based on the measurement location. Although carbon monoxide was detected earlier than the smoke near the heating source, the smoke detector reacted earlier than the carbon monoxide meter as the distance from the heating source increased. The measured concentration of carbon monoxide was much lower than the concentration generated in the case of a fire, thus confirming the applicability of carbon monoxide cross-sensing for non-fire detection.
