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 universe. 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 bus as other DALI devices such as ballasts, transformers, led lighting and many 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. These emergency tests include:

• A duration test which will test the battery periodically (either initiated from the attached control system or through a calendar inside the emergency device itself). This test can give feedback on the devices current battery status, lamp status and if the device discharged for the required time before the battery was exhausted.

• A function test which gives quick feedback on the current status of the device, battery and lamp. This test can be initiated via the attached control system or through the emergency calendar inside the emergency device
