一种适用于面积大、净空高的仓库、隧道、古建筑、电站机房等场所使用的火灾探测器——JTY—HS型红外感烟火灾探测器,今年3月下旬在北京通过了定型鉴定,将由锦州消防安全仪器厂批量生产。“红外感烟火灾探测器”是公安部沈阳消防科研所的科研成果。它是利用物质燃烧时产生的烟雾对红外光束的遮挡和散射,将光束的辐射量减到感烟动作阈值,并发出火灾报警信号的装置,对初期
A suitable for large area, high headroom warehouses, tunnels, ancient buildings, power plants and other places used fire detectors - TY-HS infrared smoke detectors, in late March this year in Beijing passed the stereotypes identification, Jinzhou Fire Safety Instrument Factory will be mass-produced. “Infrared smoke detector” is the Ministry of Public Security Shenyang Institute of Scientific Research. It is the use of material combustion smoke generated on the block and scatter the infrared light beam, the radiation dose reduced to the threshold of smoke action, and send a fire alarm signal device, the initial
