Abstract

Based on numerical simulation, the delay of smoke detector alarm was studied in this paper. The air velocity fields and smoke concentrations were introduced in to help to analyze the impact of detector location and air supply velocity on the detector alarm performance. The results revealed that the position of smoke detector had a great influence on the alarm time. Inappropriate installation position delayed the alarm; meanwhile, the delay was aggravated with larger air inlet velocity. It is of great significance to study the pattern of fire and smoke spread to determine the feasibility of a fire test system.
