Close the pipeline valve immediately. <br>2. Open the window immediately to circulate the indoor air. <br>Avoid using all items that can generate sparks (such as lighters, matches, etc.). <br>4. Avoid switching on and off electrical appliances. <br>5. Check the cause of gas leakage, and promptly notify relevant departments and relevant professionals to deal with it. After inspection, if the detector is a false alarm, the user should check whether the installation position of the detector is appropriate.<br>1、The detector uses the most advanced semiconductor gas sensor, safe and reliable, and has a long service life. <br>2、Built-in high reliability sensor, high sensitivity, can sense gas, natural gas, liquefied gas. <br>3、The gas alarm can be used to detect gas, when the gas concentration exceeds a certain level, it will immediately send an alarm signal. <br>4、Made with high-quality ABS and electronic components, has good durability and stability. <br>5、Support automatic fault detection and display, automatic reset, suitable for home use.1. This product must have the correct connection and the correct power supply. For any reason, if the power is lost, the detector will not work. <br>2. This product must be regularly maintained in accordance with the requirements of the manual. <br>3. It is impossible for the detector to have an unlimited life. It should be tested every six months. If it is found to be invalid, it must be repaired or replaced as soon as possible. <br>4. This product can reduce the occurrence of accidents, but can not sure on the safe side. For your safety, in addition to the correct use of this product, you should also be vigilant in your daily life and strengthen the awareness of safety and prevention. <br>5.
