防虫网对点型感烟火灾探测器迟滞时间的影响

The influence of mask on lag time of point fire detector

迟滞时间是反映点型感烟探测器对环境变化跟随性的指标,防虫网是影响火灾探测器迟滞时间的较大因素之一。通过实验研究了防虫网对报警迟滞时间的影响程度,提出了根据环境合理选择点型感烟探测器的方法。

Lag time is a patameter which estimates the response of the point fire detector to environmental change,the mask is a means to prevent point fire detector from accidental. There are many factors which effect the lag time of point fire detectors, and the mask is one of the most influencing factors. Studies the influence of mask on lag time, and introduces the optimize method of the usage of point fire detector based on the character of environment.
