How The Alarm Is Installed
Nov 26, 2018

Depending on the position set by the transmitter and receiver, the receiver is divided into the type of mounting mode and the reflective installation method, and instead of receiving the infrared beam emitted by the transmitter directly, it receives the infrared beam reflected back by the reflector or the appropriate reflector (such as the lime wall, the smooth paint layer on the door plate surface). An alarm signal is issued when the position and direction of the reflector change or when one of the infrared emitting beams and reflected beams is blocked and the receiver is unable to receive the infrared reflected beam.
