DALI-2 Certification of Sensors and Input Devices Is Now Underway

The Digital Illumination Interface Alliance (DiiA), the global industry organization for DALI lighting control, 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).

The first input device to achieve DALI-2 certification was the zc-switch, a push-button device from DiiA member zencontrol, which implements Part 301 of the DALI-2 specification. The first certified input device to implement more than one of the new DALI-2 Parts was the LDALI-BM2 from LOYTEC electronics, which implements both Parts 301 and 302.

Also, the first DALI-2 sensor has achieved DALI-2 certification. The zc-pir from zencontrol is a combined occupancy (PIR) and light (lux) sensor, which implements Parts 303 and 304 of DALI-2.

"Our member companies have worked together to create robust DALI-2 test specifications that will further build market confidence in product interoperability," said Paul Drosihn. "We expect to see many more certified DALI-2 products in the near future, supporting the acceleration in market demand."

For all product types, DALI-2 certification is granted only after DiiA verifies that testing is complete and successful. Certified DALI-2 products can be identified by the DALI-2 logo, and are all listed in the Product Database on the DiiA website.

About Digital Illumination Interface Alliance (DiiA):

The Digital Illumination Interface Alliance (DiiA) is an open, global consortium of lighting companies that aims to grow the market for lighting-control solutions based on Digital Addressable Lighting Interface (DALI) technology. DiiA is driving the adoption of DALI-2, the latest version of the internationally-standardized DALI protocol. DALI-2 includes more product types, more features, clearer specifications, increased testing, and product certification.
The DALI 2 certification and logo program, operated by DiiA, builds confidence in cross-vendor product interoperability. DiiA develops test specifications for DALI-2 product compliance testing, and also creates new specifications for additional DALI-2 features and functions. For more information, see www.dali2.org
