Abstract Based on the influence of characteristics and environmental factors of large space buildings on automatic fire alarm system，the utilization ratio of the maximum detection area of early smoke detection and alarm system in large space buildings is studied combined with engineering case. Based on the analysis on the characteristics of various equipments in early smoke detection and alarm system，various indicators are set including the location，height，and length；and improvement scheme is proposed for the design and products of early smoke detection and alarm system.
Key words Large space building Automatic fire alarm system Early smoke detection Detection area Air - sampling Detection alarm
