277V keypads provide configurable buttons for controlling lighting, scenes, and other connected systems, but they do not directly dim a connected load. 277V keypad dimmers combine those configurable controls with a built-in dimmer for adjusting compatible lighting loads, such as LED, incandescent, halogen, fluorescent, and low-voltage lighting.

When installing 277V keypads, plan for line-voltage wiring rated for the device, a neutral wire for configurable keypad functions, and either mains power or a compatible 36VDC keypad power supply, depending on the model. Keypad dimmers connect to a 277V lighting circuit, while three-way applications use existing in-wall three-way wiring to connect with a compatible dimmer or fan-speed controller.

277V keypad dimmers can control LED, electronic low-voltage, magnetic low-voltage, incandescent, halogen, fluorescent, and compact fluorescent loads. They support forward-phase and reverse-phase dimming, with load-type detection to help select the appropriate dimming method.

277V keypads can provide one-touch control for lighting scenes, shades, music, security functions, garage doors, and other connected automation devices through a compatible control system. Configurable buttons, backlit engraving, programmable status LEDs, and wireless communication help users identify commands and receive device feedback from one wall-mounted interface.
