The SELWR433-SAT is a pluggable receiver operating on a frequency of 433.92 MHz in AM/ASK modulation. Thanks to this receiver, it is now even easier to assign transmitters to the Atrium system! The SELWR433-SAT receiver has to be plugged into the Atrium board to receive the Wiegand signals of the transmitters. Once the transmitters are accepted, their serial number is sent to the Atrium system via a Wiegand signal. From that moment on, the transmitters are ready for use. Simplicity and convenience.
