High-Density Multi-Button Control with Executive Metal Finish

Designed for environments requiring centralized management of multiple lighting circuits, HVAC states, motorized curtains, and custom scene presets, the Smart Laffey D29 Series packs high-density control capability into a single compact faceplate. Built with precision-machined metal button keys, the D29 offers robust wear resistance and a sophisticated tactile feel tailored for high-end architectural interiors.

Universal Multi-Protocol Integration for Smart Buildings

The D29 Series integrates effortlessly with major building management networks and Room Control Units (RCU), supporting KNX, Tuya Zigbee, RS485 bus protocol, dry-contact IO, and Matter standards. Operating across low-voltage bus systems (12V/24V) or standard 220V AC mains circuits, it provides seamless multi-point control across both commercial hospitality and high-end residential setups.

Key Features & Product Highlights

  • Multi-Button Metal Panel Architecture: Configurable key layouts (including 8-button key density) to consolidate multiple lighting and scene controls onto one wall panel.
  • Universal Protocol Support: Native compatibility across KNX, Tuya Zigbee, RS485, dry-contact IO, and Matter protocols.
  • Acoustic Noise Reduction: Integrated TPE elastic dampening absorbs button actuation and rebound sounds for near-silent operation.
  • Soft LED Backlight Illumination: Anti-glare multi-color LED backlighting provides subtle key orientation in dark or dimmed rooms.
  • Modular Multi-Gang Framing: Mounts universally into 1-gang through 5-gang continuous modular frames in metal, glass, or plastic finishes.
