DALI Emergency

DALI Emergency

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 certified products

DALI-2 certification is now open for control gear for self-contained emergency lighting. >> View press release (September 2021)

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.

SPECIFICATIONS

Tests for DALI-2 Emergency certification are developed by the DALI Alliance, based on Part 202 of IEC 62386
Control gear in Part 202 are also known as device type 1 (DT1)

BACKGROUND

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.

In many countries, there is a legal requirement for periodic testing of emergency lighting. DALI enables self-contained emergency tests to be automated, triggered by DALI commands or by an optional timer.

Emergency control gear must implement both a function test and a duration test. The function test is a quick test of the battery, charging circuit, driver/relay and lamp, while the duration test ensures that the battery will be able to operate the lamp for the full rated duration (for example 1 hour or 3 hours).
