Because of its active inhalation function, inhalation smoke detector is easier to detect fire factors than traditional point smoke detector. For the problem of smoke retention layer and a large amount of diluted smoke, the air sampling pipe can be arranged near the position where the fire coefficient is easy to be detected by taking advantage of the flexible arrangement of the inhalation smoke detector. If the particle counting type air-breathing detector is used, it will have little influence on the problem of smoke retention layer and a large amount of diluted smoke, because the weight of invisible particles produced by fire can be ignored compared with smoke, and it can be taken to a higher space, with little heat energy, which can be easily captured by the detector and will not be missed. Moreover, the number of these invisible particles is huge, and the impact of being diluted in large quantities is not as serious as that of smoke. So the effect of early detection is more obvious.
As for the convenience of maintenance, the sampling tube installed at an altitude above 12 meters is made of PVC or ABS and does not contain any detection electronic components, so it is only necessary to blow the dust accumulated in the tube in the opposite direction with an air compressor regularly. The testing host can be installed at the height where ordinary people can stand for maintenance, so ordinary maintenance is not affected by the height above12m.
