Lutron RadioRA 2 GRAFIK T RF C•L Hybrid Keypads Specifications
Introduction
The Lutron RadioRA 2 GRAFIK T RF C•L hybrid keypads combine a dimmer and a keypad in a single unit, offering an ideal solution for renovation projects by eliminating the need for two separate devices. These keypads function as normal keypads even when no load is connected or if the load fails.
Features
- Customizable, backlit, engraved scene/zone descriptions on the faceplate.
- Dynamic Backlight Adjustment (DBM) automatically sets backlight intensity for clear text visibility in any lighting condition.
- Fully programmable buttons, including raise/lower functionality.
- C•L technology with microprocessor-based dimming for compatible LED lamps.
- Optional neutral connection for superior LED dimming performance.
- Simple tactile feedback.
- Distinct architectural appearance.
- Adjustable high-end and low-end trim settings for enhanced LED dimming performance.
- Installs in single-pole or multi-location applications. Auxiliary devices are available for multi-location control (up to four auxiliary devices per keypad, one master control per circuit).
- Uses Lutron GRAFIK T wallplates (sold separately).
- GRAFIKT wallplates attach with invisible fastening means.

Design Attributes
- When neutral is connected, the hybrid keypad can operate as a normal keypad even without a load.
- If a load is connected, the top button will activate the load.
- The internal dimmer can be assigned to any button and controlled by any keypad.
- Can be installed in single-pole or multi-location setups using auxiliary devices. Auxiliary devices control the local lighting zone only.
- Can be wired in 2-wire or no-neutral applications.
- Dynamic Backlight Adjustment (DBM) automatically sets backlight intensity for clear text visibility in any lighting condition.
- Buttons provide smooth, gradual light transitions or shade/drapery movement.
- Buttons are programmable for scene or room preset levels, or for raise/lower functions.
- Faceplates are ordered separately and can be custom engraved with scene or zone descriptions.
