Function introduction The detectors, which are based on CPU, with mutual correlation detecting, are a new type of multi-beams active infrared detector. The detectors, which are slim-line design, are made up of the master detector and the slave detector. The active infrared detector is powered by the control panel or outer power supply, forming an invisible beam wall between the master detector and the slave detector to fulfill the tightly-enclosed guarding of the protector. If any outlawed intrusion occurs, the detector will send alarming signals to the control panel, or the detector will directly drive the high-power siren to give an on-the-spot alarm through electric cable or wireless transmitter.
