摘要
分析点式感烟探测器、缆式线型定温探测器、红外光束感烟探测器在地铁电缆夹层、高大的车库空间、装修方案复杂的车站站厅公共区、站台公共区等场合应用的不足,通过对吸气式烟雾探测技术与传统的火灾探测器在地铁环境中的应用特点进行对比分析,说明吸气式烟雾探测系统具有安装灵活、易维护等特点,推荐在地铁上述重要或特殊场所采用吸气式烟雾探测报警技术。
This paper analysed the weaknesses of adopting point-smoke detectors, linear heat detectors, infrared beam smoke detectors in the current laminated cable floor, large garage space, concourse with complex decorations and public areas of station platforms in subways. It introduces the trend for using air sampling early alarm smoke detection （ASD） in the subway environment by comparing the peculiarities between the traditional and the new fire alarm technologies. The subway ASD technology features easier installation and maintenance which is recommended to be adopted in the above-mentioned critical and special areas in subways.
