Alarm density: coal gas 0.1-0.5％; natural gas 0.1-0.3％ ;LPG gas 0.1-0.5％
Working voltage : AC220V
Working environment : temperature ：-10- 50ºC relative humidity ≦97%
Working current : ≥100mA
Alarm voice : ≥85db
Response time : ≤20 second , according to the gas density
First,make sure the density rate of gas and air, then fix the gas detector to a suitable place in 1.5 m radius . coal (nature) gas are light than air ,upon the air LPG is heavier than air ,sedimentary low place.
1. Connect power source2. The green light will blinking, the device is in warming up.3. Once green light will be stable device is activated.4. When it detect the gas leakage, the green light will become red and flashing, along with the buzzer sound alert.
1. Do not install outside2. Do not install ventilate pore, door etc. air flow strongly site.3. Do not install on the place over - 10degree to 50 degree .4. Do not install in humidity place.5. Do not install on the place something block.6. Do not use glue, pesticide, dope,diluent etc.7. If has trouble,do not dismount repair by yourself.
When combustible gas density overrun thestandard, the siren will keep in alarm ,you should:
1. shut the pipe spigot right away!2. open window keep air circulated right away!3. cut off all the fire source and keep away the tinder( lighter, match etc.)4. keep away all power switch, electrical equipment.5. check leakage reason, and inform relative department to deal with !
