Replace an existing wall switch with the Keypad Linc, set up your I/O Linc Garage Door Control & Status Kit and wireless link one button on the Keypad Linc to the I/O Linc. Now when the garage door opens, the LED on that button will light up. Press the button to close the garage. It’s that simple. Easily expand the other unused buttons on the Keypad Linc to control the garage lights or any other light in the house. Just add additional INSTEON-compatible wall switches or plug-in modules to the lights you want to control.
