If you have a security/home automation set up in your home, you can easily add wireless RF control to almost any device. Send a signal to the 1-Channel RF Receiver from a 1-Button, 1-Channel Slimline RF Transmitter (sold separately) to unlock secure doors, control house lights or garage doors, or signal your alarm panel. Get creative: You can use this RF system to add remote control to almost any electronic device or system. The 1-Channel RF Receiver's relay output can be programmed for one of four different modes, depending on the application: 4-second momentary, 1-second momentary, toggle, and latch. Up to 15 different transmitter buttons can be programmed to each 1-Channel RF Receiver, so every member of your household can access the RF remote control feature. Set up multiple RF control devices in your home: A 2-Channel Receiver and a 4-Channel Receiver and corresponding transmitters are also available.
