X10 PRO Wall Transmitter Base Module (XPT-NS)

Create a custom X10 wall switch with the X10 PRO Wall Transmitter Base Module. This X10 transmitter installs in a standard single-gang wall box and wires into your powerline. Simply decide how many X10 receivers (1, 2, or 4) you want to control with the switch, and then attach the appropriate keypad faceplate (sold separately). Once installed, you have both local and X10 remote control over your X10 receivers! How It Works: The transmitter base can control multiple X10 receivers by running the Unit Number Addresses in sequential order. In other words, if you have the dials on the transmitter base set to House Code B and Unit Code 4, a four-button keypad will control the X10 receivers set to House Code B and Unit Codes 4, 5, 6 and 7. The top button will control Unit Code 4, the next button below will control Unit Code 5, and so on.
