APPLICATIONS
LHR302 series gas detector is a kind of Ceiling type household gas leak alarm designed to detect the concentration of combustible and toxic gases or vapors . It provide a visual and audible signals when the concentration of the gas get to a preset level . The alarms are available for liquefied natural gas (LPG), natural gas(Methane) , propane, Hydrogen, town gas ,smoke,etc. They are not only installed at home ,but also used at any other potentially hazardous areas.
SPECIFICATIONS
Work voltage: DC12V
Sensor type: Catalytic gas sensor
Operating temperature : -10—45℃ Relative humidity ≤95%
Target gas: Combustible gas
Response time : ≤20s
Size/N.T: D115mm X H46mm @70g
INSTALLATION
1.INSTALL The Gas leak alarm 0.3 meter above the ground for LPG Gas or 0.3 meter below the roof for LNG and H2 with good air circulation.
2.Connecting DC 12V power source.
3.The gas leak alarm needs about 1 minutes warm-up. It works
properly by showing “GREEN LED LAMP”-ON,“RED LED LAMP”& “BEEP-OFF”.
4.When gas escapes,‘WARNING’ The Gas leak Alarm will be proceed with RED light indication and non-stop “beep--” sound. Both stop when safety is found.

三、使用说明
1、在您安装使用LHR302型气体报警器时,对于天然气、甲烷、一氧化碳、氢气请将其安装在距屋顶以下1米左右处;对于丁烷、LPG,请将其安装在地板上方1米左右处。气体报警器安装处应有良好的空气流通条件。连接联网信号常开触点进入监控主机相应端子。
2、启用
*将报警按器接入电源。预热1分钟,在此时间段内报警器无检测功能。
**预热1分钟后,报警器即进入监测状态。此时可用“二”条款中给出的相应气样浓度进行检验。
***当报警器所处位置空气中的被测气体浓度达到或超过“二”条款中规定的值时,报警器红色指示灯亮,并发出“嘀,嘀”报警声,常开触点闭合,传送联网信号给监控主机。此时,请立即切断气源,打开窗户,严禁开、关任何电器,并速请专业人员前来排除故障。
