About DALI emergency
Traditionally the emergency control standards used to monitor emergency devices has been locked away behind propriety standards. The introduction of DALI as an international lighting control interface has led to the creation of the DALI emergency control definition.
DALI emergency is defined within the extended commands of DALI with the DALI emergency device defined as TYPE 1 within the DALI protocol. Ballast are defined as TYPE 0 while halogen converters are defined as TYPE 3. This standard allows the use of emergency lighting devices on the same DALI line as other DALI devices such as ballasts, transformers, led lighting and other lighting types.
The DALI emergency standard allows for emergency devices to run two key emergency tests as well as feeding back many other pieces of important information.
