What is the principle and function of infrared anti-beam alarm?

Answer: Principle: Use infrared rays to emit diodes through LED infrared light, and then focus processing by optical mirror to make the light reach a long distance and be received by the receiver. An alarm is issued when the light is interrupted.

Role: The detector using the beam interruption method blocks an invisible infrared beam and triggers an alarm when someone crosses the monitoring protection area. Commonly used for room alarms. A transmitter only needs a 2-core power cable (the line depends on the distance and environment of the site, generally RVV2 * 0.5), and a receiver requires a 2-core power cable and a 2-core signal cable. Except for buses and other hosts; the line must be based on the distance and environment of the site, generally RVV4 * 0.5).
