Because of the detection of heavier-than-air gases, the need to install the gas detector closer to the ground, usually about 30cm from the floor can be fast, accurate and stable detection of the gas concentration, so as to take a response to the safety measures.
To detect lighter-than-air gases, the gas detector needs to be installed closer to the ceiling, usually about 30cm from the top. It should be noted that the gas detection alarm controller host installation location standard 160cm from the ground, to facilitate the operation of the operator, but also to avoid the instrument itself becomes an obstacle.
Second, the gas detector probe wiring
Gas detector probe wiring is very simple, the premise that you need to know the detection environment should be installed a few probes, and then according to the number of probes to choose three-wire or four-wire system, out of the follow-up to increase the number of probes, it is recommended to use the four-wire system to facilitate the subsequent increase in probes and maintenance.
After determining the use of four-wire model output, you need to detect the number of gas detector probes and detect the location of the gas to set up a reasonable alignment line, this piece is very simple, only need to be connected in series, the use of splitter boxes will be connected to the probe can be connected one by one.
Three, fixed gas detector and debugging
Selected gas detector probe location and line alignment, the rest is physical work, only need to fix the gas detector probe and the line of power lines can be. After checking, power on the test.
