Combustible gas detector is a very practical safety equipment, which can detect the combustible gas in the air in time, such as methane, propane, acetylene and other toxic gases, and avoid the occurrence of potential dangerous events. The installation of a combustible gas detector is a very critical operation, and attention should be paid to details to ensure the normal operation and detection effect of the equipment. This article will introduce the installation method and precautions of combustible gas detector.

1. to select the installation site

first need to select the appropriate installation site. Normally, combustible gas detectors should be installed in areas where air is circulating and susceptible to combustible gas contamination. Because if the installation location is close to the source of combustible gas, it may cause the sensor to false alarm or false alarm. At the same time, be careful not to install the detector in high temperature, humidity, darkness or mechanical vibration environment, these conditions will affect the accuracy and life of the detector.

2. preparations before installation

Before installing the combustible gas detector, you need to check whether the equipment is intact, whether the sensor is clean, and whether the back plate is firm. At the same time, it is necessary to prepare installation tools and the required cables, power supplies, etc.

3. to install the detector

1, fixing the back plate
First, the back plate needs to be fixed at the installation position. Select the appropriate size and material of the fixing plate, and fix the detector on the wall or ceiling with screws. Make sure that the fasteners of the back plate are secure and reliable.

2. Connecting the circuit
Then, the cable needs to be connected to the back plate of the combustible gas detector. Make sure the cable passes through the wall or ceiling and connect it to the detector. At this time, pay attention to ensure that the connected wires are in good contact, and the length of the cable should be sufficient, but not too long.

3. Test whether the detector can start normally after
installation. Connect the power supply to the detector to observe whether the detector performs self-test reliably, and can correctly detect the presence of combustible gas and send an alarm.

4. Precautions

1. Select the appropriate installation location to ensure the suitability of the detector's working environment.

2. Before installation, check whether the equipment is intact, whether the sensor is clean, and whether the back plate is firm.

3. Pay attention to good wire contact when connecting the circuit. The length of the cable should be enough, but not too long.

4. After the installation is completed, test whether the detector can start and work normally.

5. The installation of combustible gas detectors shall comply with the corresponding safety operation procedures and standards to ensure the effectiveness and safety of the equipment.
