DALI-2 Emergency lighting control strengthens interoperability

Certification of DALI-2 control gear for self-contained emergency lighting adds interoperability to DALI features such as automated testing and reporting.

September 28, 2021

The DALI Alliance has extended its highly successful DALI-2 certification program to include control gear for self-contained emergency lighting. Focused on device interoperability, DALI-2 certification is built on open, international standards.

DALI emergency lighting is widely used as a robust and reliable solution that meets safety-critical requirements in buildings throughout the world. The DALI protocol enables integrated, digital control systems that combine illumination and emergency lighting.

DALI-2 Emergency further extends interoperability of lighting-control devices and facilitates integration with building management systems, which can access DALI control and querying capabilities including automated testing and reporting.

Emergency lighting, which provides light when the mains supply fails, is a critical feature that is mandated by various regulations. “Self-contained” means that the battery – which provides power during an emergency – is inside, or placed next to, the luminaire.

“While the industry has enjoyed the benefits of DALI emergency lighting for many years, the introduction of DALI-2 Emergency is a huge step forward,” says Paul Drosihn. “For DALI-2, the level of testing has increased dramatically, and the results are independently verified. This means that the industry can have a great deal of confidence in the interoperability of certified DALI-2 devices.”
