The RFX Wireless RS-485 Communication Modules provide a means of communication between the FalconXT system controller and RS-485 devices such as keypads, or between any two remote devices using RS-485 communications. These modules are perfect for retrofit applications where wiring does not exist, can't be added, or is cost prohibitive. Capable of communicating over several miles line-of-sight, the RFX wireless modules can even communicate over large distances to remote facilities. Three antenna options are available to fit your needs perfectly.
