Digital Addressable Lighting Interface (DALI) is a control protocol that makes it possible to control luminaires which have DALI control gear individually. The system allows user-friendly light management in architecture and can be integrated as a subsystem into modern building control systems. The two-wire control line with a transfer rate of 1.2 Kbits/s can be run together with the mains supply cable in a 5-core cable. The bidirectional system allows feedback from the luminaires on different aspects such as lamp failure. The DALI protocol limits the number of devices to 64. The standard version stores the settings for a maximum of 16 luminaire groups and 16 light scenes within the control gear. General information on DALI: www.dali-ag.org
The ERCO Light System DALI, saves settings in a central controller with a greater storage capacity. This allows more luminaire groups, light scenes and fading times along with the coding of the control gear memory for other features. The system is compatible with other DALI devices. Light System DALI can provide both economical light management and scenographic lighting.
