Combustible gas combustible gas prices on the market many brands of manufacturers combustible gas alarm device, be sure to look for when buying factory original, so late after-sale find people. Shenzhen Yongchang Electronics Co., Ltd. Yongkang is the leading brand of combustible gas alarm brand. Its scale of production in the country is one of the best. Quality and development, with good after-sales service for backing, the general public has become the most popular brand alarm. Core components Yongkang combustible gas is gas sensors, when the gas concentration in the air exceeds a set value detector alarm is triggered, and external audible alarm signal, if the alarm center and connect the control panel can be networked alarm , and can automatically start ventilation equipment, shut off the gas pipe valves, etc., to protect life and property safety. Use Yongkang combustible gas is an important means to deal with gas invisible killer. Gas experts pointed out that a gas leak or exhaust emissions of carbon monoxide produced in large amounts is the source of gas poisoning in the response, such as mining of useful combustible gas can get timely warnings. Authorities the long-term tests are also concluded that more effective combustible gas to prevent carbon monoxide poisoning accident rate 95%. 1. Performance and specifications. Detection of gas: natural gas, LPG, city gas (H2) Operating voltage: 220VAC or 110VAC, 12VDC-24VDC Working temperature: -10 ℃ - + 50 ℃ Working environment: Humidity ≤97% RH linkage function: linkage can be equipped with an exhaust fan manipulator, solenoid valve Networking: Wired networking: (NO, NC) Wireless networking mode: 315MHZ / 433MHZ (2262 OR 1527) Product Specifications: Weight: 240g Dimensions: 110 * 70 * 40mm Box size: 144 * 105 * 53m 2. Each component name or description of each part of the line. 3. Rationale combustible gas. 1. Power light: green, power and lights up when the alarm goes off. Alarm LED: red, alarm lights, stop the alarm goes off. 2. Power, green light or flashing three minutes later, the alarm began to work properly. 3. When the detected gas reaches the alarm point, the alarm began to alarm, the green light goes off, the alarm LED lights, the buzzer "BB .." sound the alarm, when the concentration of the detected gas down to the alarm point, the alarm then stop the alarm. (Carbon monoxide alarm has delay function) 4. Adds manual detection function, when pressing a button, the green light is off, the alarm LED lights, buzzer "B, B ..." sound the alarm. 5. If the increase in the United fan function, when the alarm alarm, has been connected to the exhaust fan started automatically remove harmful gases. 6. If the increase in the United manipulator or solenoid function, when the alarm alarm, has been connected to the robot or the solenoid valve will automatically close the gas valve, thereby cutting harmful gas source. 7. If you increase the networking function, when the alarm alarm management center or the control center at the same time receive normally open and normally closed (NO, NC) signal. (For increased wireless capabilities, the control panel will receive a radio signal 2-3 seconds) after an alarm output relay passive contact signal (normally open, normally closed can be patched) for controlled ventilation ventilation equipment or other devices normally open or normally closed for the alarm contacts. 4. Combustible gas installation method. In the selected wall position, corresponding to the mounting plate two random installation holes ready punch mark (on-board hooks should level up); lay the mounting holes into the supplied installation stopper, and then use random from tapping screws fixed to the wall mounting plate; three holes on the back of the body aligned mounting plate fixed hooks, hang the body; the connection correlation output signal, the power. 6. Maintenance and repair. We recommend that each quarter of a cleaning product, the product of one test per month (press the test button to test whether the combustible gas audible alarm) If you are interested in Yong Kang combustible gas can contact the manufacturer of staff Yu Xiansheng 0755 6,151,238,913,332,928,292
