摘要
结合国内外有关规范对线型红外光束感烟探测器的安装要求,运用火灾模拟软件FDS,对高大空间线型红外光束感烟探测器的响应性能进行仿真;研究探测器光路长度对报警时间的影响,指出当探测器光路长度不同时,探测器的响应性能有很大差别;提出不同灵敏度设置下发射器与接收器之间的合理安装间距。
In view of the installation for linear infrared beam smoke detector requirements specified by related domestic and international regulations, uses fire simulation software FDS to simulate the response performance of linear infrared beam smoke detector in large spaces; studies the impact of optical distance ot a detector on time of fire alarming, and point out that the response performance of a detector may vary significantly at different optical distance; provides the reasonable mounting distance receiver of different sensitivity between transmitter and settings.
