JGD一1型红外感光探测器,对火灾的响应速度快,通用性较强,可以配用于多种报警箱和灭火装置。探测器性能比较稳定,电路工作比较可靠,结构比较简单,适用于大楼、仓库、计算机房、恒温室、变电所、燃料库等场所,特别适用于没有阴燃阶段的易燃液体火灾的早期检测。此种探测器可在-25℃一45℃环境下使用,静态工作电流小于5毫安,视场角为90°×90°,响应时间小于5秒,可以检测到距探测器5米外的10厘米油盘的火光,是我国自动火灾报警装置的新品种。这种探测器是公安部上海消防科学研
JGD-1 infrared photodetector, the fire response speed, versatility, can be used for a variety of alarm boxes and fire extinguishing devices. Detector performance is relatively stable, more reliable circuit work, the structure is relatively simple, suitable for buildings, warehouses, computer rooms, thermostats, substations, fuel depots and other places, especially for non-smoldering phase flammable liquid fire early Detection. This detector can be used at -25 ℃ a 45 ℃, the working current is less than 5mA static, angle of view of 90 ° × 90 °, the response time of less than 5 seconds, you can detect from the detector 5 meters away 10 cm oil pan fire, is China’s new automatic fire alarm device varieties. This detector is the Ministry of Public Security Shanghai Fire Research
