On light will be obviously reduced, then light-sensitive element is just converted into the variation of light intensity the variation of electric current, is sent out by amplifying circuit
Go out alarm signal；Air suction type, aspirating smoke detector changes traditional smoke detector, and to wait for smog to drift detector passive
The mode detected, but use new theory, i.e., Sample acquisition actively is carried out to air, when the air sample in protection zone
Sampling conduit is sucked by the asepwirator pump inside aspirating smoke detector, detector is sent to and is analyzed, if it find that smog
Grain, that is, send out alarm.Existing many fire detectors the problem of there is energy consumption is high and poor accuracy, to fire detector
Inhibition is played in popularization.
