Home combustible gas supply one million insurance co-brand of CCTV specified Yongkang brand household combustible gas. Yongkang brand household gas gas gas leak detectors from Shenzhen to automatically cut off the gas pipeline, gas continues to prevent leakage. Yong Kang household gas leak alarm effectively detect a gas leak, a timely audible alarm to alert users to take security measures to prevent toxic gas leak and explosion occurred, reduce household hazards, protection of life and property safety! Installation and wiring 1. First determine the required gas detection heavier than air or lighter than air, heavier than air gas: liquefied petroleum gas; lighter than air gas: Natural gas, artificial gas, methane. 2. Install the detector in a suitable place according to the severity of the gas. Probe gas is heavier than air: Installation in above ground installation in less than the ceiling of 0.3-1.0 0.3-1.0 meters away from the gas source radius 1.5 Mi Neimi, from the air within a radius of 1.5 m; probe gas is lighter than air: Installation in less than a ceiling of 0.3-1.0 meters away from the gas source within a radius of 1.5 m (see below). 3. Attach the mounting screws on the wall, hang detector. 4. Family should also pay attention, the installation location can not be too close to the gas stoves, in order to avoid stove flame detector by baking; fumes can not be installed in large areas, in order to avoid false alarms or lead to air intake probe poor intake, thus affecting the detector sensor sensitivity; can not be installed on the exhaust fan, doors and windows at the side and a large bathroom moisture. 5. All the wiring installation must comply with valid national and local regulations, and standards. The thickness of the wire core should be appropriate wires detectors and other auxiliary devices shall be color logo, so as not to pick the wrong line. Improper connection will result in the event of a gas leak, not the normal police. Operating instructions for this product can be used alone as a detector, but can also drive solenoid valve. Specific instructions are as follows: 1. The detector installed in the proper position, the probe power plug into the power outlet. 2. Turn the power detector, the buzzer "beep" is heard, the circuit enters warm-up state, then the power indicator light flashes once per second (about three flashes 3. The solenoid valve connected state: the positive solenoid valve solenoid valve connected to the detector output line red line, the solenoid valve solenoid valve and the detector output negative line of black cable. The detector detects carbon monoxide or combustible gas leaks, carbon monoxide or combustible gas alarm lamp blinks buzzer "beep - beep" alarm sound, the detector output signal for driving the electromagnetic valve cut off the gas supply, carbon monoxide or flammable gas is removed, the detector automatically returns to the monitor state 4. Fault indicator was accompanied by bright yellow long beep. sounding device, showing internal fault detector. 5. Detector internal fault, turn off the detector off, and then turn on the detector again self, still reported fault, should cut off the power supply, contact a service center Product Test combustible gas test: After the detector is installed, can be used with no ignition lighter way, away from the gas convection Window> 5cm or so from the release of some of the gas to around to test the detector alarm, the detector combustible gas alarm indicator glows red and flashing buzzer happen "beep - beep" sound the alarm when the gas concentration is lower than the concentration of combustible gas alarm detector will stop alarm enter into the normal monitoring state do not use too much gas frequently test, this would reduce the gas. sensitivity sensitive components.
