X-10 Transceiver Module - Model RR501

As the heart of your X10 system, the RR501 X10 2-Way Plug-in Transceiver Module is both a simple and convenient tool for controlling your home or business environment. The RR501 Transceiver picks up radio frequency signals from X10 wireless remotes like the MS14A motion sensor and KR19A Keychain remote. It also reads signals sent over your existing home wiring, and sends them to all X10 modules connected via that very same wiring. No need to run new wires or costly cables.
