Specification: status: New Operating voltage: 110-240v Static power consumption: <2w Alarm concentration: Liquefied gas 0.1% - 0.5%; Natural gas 0.1% to 1%; Town gas (H2) 0.1-0.5%; Gas response recovery time: ≤30s; Alarm volume: ≥70dB Working environment: humidity ≤97%RH; Temperature 15℃ - +50℃ Optional Plug: USA, EU Package List: 1 x Gas Detector 1 x Instruction Installation Instructions: 1. Alarm installation location: within 1.5 meters of the air source with good ventilation. (1) LPG has a higher density than air and remains in a low place after a leak. The alarm should be installed in a location approximately 0.3 meters from the ground. 2.Unable to install alarm position: corner, cabinet and other positions difficult to circulate air; easy to smoke directly, like the lampblack position. Application: 1. Power indication: green light, power on, when the alarm goes off. 2. Alarm indicator: red light, flashing when alarm. 3. Turn on the power, the light green or flashing for 3 minutes, the alarm starts to work normally. When the combustible gas leak is detected to reach the early warning concentration, the alarm starts to sound, the green light turns off, the red light flashes, and the continuous sound alarm of "drip-drip-drip" is issued. When the detected gas concentration falls below the early warning concentration, the alarm stops alarming. Regular tests: 1.Every month with lighter gas in the gas hole, 5-8 seconds after the alarm, the alarm should immediately sound and light up, indicating that the alarm is working normally. 2. Please always remove dust and grease near the air inlet to prevent the ventilation holes from being blocked. 3. Press the test button to simulate the alarm and check if the alarm is in good condition. Alarm handling methods: (1). Please open the door and window immediately to ensure air circulation, turn off the harmful air source, do not open or close any electrical switches at this time, to avoid combustion or explosion of spark ignition gas. (2). Report immediately to the gas management department, through professional inspection and treatment. (3). After handling by professionals, the alarm must be ventilated.
