New generation digital frequency Infrared 4 beams detector

Working principle:

The EB800-ABH series are Three photoelectric detectors designed to provide reliable perimeter security both indoors and outdoors.
It consists of separate transmitters and receivers. The transmitter emits invisible infrared beams with changing frequencies to the receiver. The frequencies change in a certain range to protect beams from disturbance.
This detector uses 4 pulsed infrared beams that are designed to activate an alarm only when 3 beams are simultaneously blocked.

Features:

Four beams
Digital frequency conversion
Active infrared detector
Three beams simultaneously blocked inspection
Infrared LED lighting
PC engineering plastic material
Dew and frost proof solution: Heating housing
Other additional function: Photic instruction, OK instruction, test terminal
