in many industrial production fields, the use of combustible gas alarm can carry out fast, reliable and stable monitoring of gas or combustible gas. when the monitoring concentration reaches the preset alarm value of combustible gas alarm, the sound and light alarm will be linked to prompt the field staff to take necessary protective measures. However, in the process of installing combustible gas alarm, we generally need to wire first. Do you know what wiring requirements should be met for the field installation of combustible gas alarm ? The following is a brief introduction by yi yun Tian:

Combustible gas alarm field installation wiring shall meet the following requirements:

1. The threading hole of combustible gas alarm should be blocked, and protective measures should be taken for the detector after installation.

2. the connecting wire of combustible gas alarm shall have a margin of not less than 150mm and shall have obvious signs at its end.

3. The combustible gas alarm can only be installed when it is about to be debugged. It should be properly kept before debugging, and dust-proof, moisture-proof and corrosion-proof measures should be taken.

4. Three-core shielded cable shall be used for the wiring of combustible gas alarm probe. The single wire diameter shall be greater than 1 mm². The shielding layer must be grounded during wiring.

5, combustible gas alarm should be installed firmly, and the wire connection must be reliable crimping or welding. When using welding, should not be used with corrosive flux.

6. the combustible gas alarm shall be wired under the condition of power failure, and power on after confirming that the wiring is correct; When it is confirmed that there is no combustible gas leakage on site, the probe shall be opened and debugged.

To sum up, it is some relevant requirements that the on-site installation wiring of combustible gas alarm should meet. The product performance and quality of combustible gas alarm is directly related to the personal safety of employees at the work site, and it is one of the guarantees of safe production.Therefore, we can better ensure the smooth operation of the combustible gas alarm by meeting the relevant requirements of the on-site installation and wiring of the combustible gas alarm.
