Its principle is: high sensitivity aspirated feeling smoke detectors, that is very early fire detection system is through the extremely high sensitivity of air pollution by monitoring equipment from detectors or area air samples from continuous analysis to determine whether one have smoke ingredients. This type of detector is a kind of turbidity plan than the traditional smoke detector sensitivity high hundreds of times.
Asd system pipe is usually installed in the ceiling, or upper, each tube in the appropriate drilling sampling interval has holes. Air pump or breathe in through the pipe and sampling machine hole continuously will air learned in the probe. Air samples of the smoke concentration and a group of calibration is critical in smoke. If air samples of the smoke concentration in advance of the calibration smoke more than ? critical value
