BEA sensors are ideal for the wireless activation and/or sequencing of automatic doors. A unique rolling code is transmitted each time the transmitter is activated (thus providing a secure signal). Since receivers can be individually programmed, multiple receivers can be programmed differently thus allowing for sequencing in multiple applications. Those receivers programmed with NO DELAY will be active immediately upon receiving the transmitter signal. Those receivers programmed with a DELAY will activate at the end of their pre-determined time delay set by the potentiometer.
