Difficulties with gas alarm

The gas alarm, as a part of the anti-theft alarm system, has already contributed to the anti-theft alarm industry, but how to solve it if it fails during installation?

If the gas alarm in the gas alarm system cannot be searched, first confirm whether the address code of the detector has been set. It is strictly forbidden to set the address code of the detector repeatedly. In the same system, the detector can only have one address code, external output input The address code of the module can be independent of the detector address and can be repeated. Check whether the connection cable of the detector in the gas alarm system is reversed. If the GND and S2 of the controller are reversed in a long distance, it may cause the problem of incomplete search of the detector. Special attention should be paid. The voltage at the end is too low. Use a multimeter to detect the power supply voltage of the detector on the line farthest from the controller. The normal voltage should not be much lower than the voltage output by the controller, and it should be stable, otherwise it may be because of the end Poor power supply caused the detector to fail to work properly. The gas alarm does not find the detector. If the host does not find the detector, it will definitely not alarm. The host should be operated to search for the detector. Check whether the spray test operation mode is correct, the calibration gas is normal, the test distance is too far, and the test flow is appropriate.

In short, the advent of gas alarms is an extremely important way for us to protect our safety, let us wait and see.
