DiiA has introduced DALI-2 certification for a range of products including light sensors, occupancy sensors, push-buttons, switches and sliders. These products, known as DALI-2 input devices, provide user-derived and environmental information to the lighting-control system.

“This is a significant milestone for DALI-2,” said Paul Drosihn, DiiA General Manager. “Now, all the main components of a lighting-control system can be DALI-2 certified.”

In addition to input devices, DALI-2 already includes application controllers (devices that make decisions and send commands); bus power supplies; and control gear such as LED drivers.

The DALI-2 test specifications for input devices were written by DiiA, based on Parts 301, 302, 303 and 304 of IEC 62386, the global DALI standard. Part 301 covers push-button devices, Part 302 specifies absolute input devices e.g. switches, sliders, Part 303 covers occupancy sensors, including presence and movement sensors, and Part 304 defines light sensors. A DALI-2 input device will implement Parts 101 and 103, as well as one or more of the new Parts (301-304).
