Draper Wireless Transmitter, RF Type (WRT), 110V

The WRT is Draper's handheld radio-frequency transmitter for a 110V motorised screen, giving three-button up, stop and down control through an LVC-IV low-voltage control module. Because it is RF rather than infrared it does not need line of sight, which is what makes it the right choice when the control position is behind a lectern, off to one side, or in a room where nobody stands still.

The receiver is already in the LVC-IV, so no extra hardware goes on the wall. The remote does have to be learned to the module during commissioning - a one-off pairing step rather than a fixed channel.
