WR4 RADIUM Stand-Alone Wireless Receiver (4-Relay)

The WR4 is standalone RADIUM receiver by CDVI. This mini sized 4-channel model uses Keeloq Hopping code and 433.92 MHz frequency.

The WR4 stand-alone wireless receiver is compatible with any RADIUM 433 MHz wireless remote (except the AES128 line). This is the ideal solution for automatic doors, gates and lights. All models use the secure KeeLoq® Hopping code and a special algorithm to keep a continuous synchronization between transmitters and receiver. The standard range can be enhanced by installing the optional SEA433 antenna.
