＊Adopt patent gas detector, lower consumption, longer lifespan.
design to induct coal gas, natural gas and petroleum gas.
＊Intelligent control, check by themselves, prevent from wrong alarm, exterminate missing alarm, be more reliable.
＊Be used singly or used with alarm system. Alarm by voice and ray.
Kinds of gas: coal gas, natural gas and petroleum gas
Alarm density: 0.1% to 0.5%(coal gas, petroleum gas)
0.1% to 0.3%( natural gas)
Voltage: 9-15v DC
Operational temperature: -10℃ to 50℃
Humidity: less than 97%
Transmit frequency: 315MHz
Alarm decibel: more than 85db
Respond time: less than 20s (according to density of gas)
Dimension: 80×75×29 mm
First assure the proportion of combustible gas and atmosphere, and then fix SG-278 gas leak detector on the position, which are 1.5M far away from gas source.
·Coal gas & natural gas: Lighter than atmosphere, float in the higher place
·Petroleum gas: Heavier than atmosphere, sink in the lower place
After connect the power, there will be a ”click” sound from detector. It enters into normal working status if power LED (red light) shines at the same time. When there is gas leak, the detector will give out two “click, click” alarm sounds and alarm light shines. Then the alarm message will be sent out. After getting rid of alarm event, the detector will resume normal working status.
If there is something wrong with detector, it’ll give out “click” long sound. The stoppage light will shine all the time. And alarm message will be sent out. After getting rid of it, the detector will resume normal working status.
