DALI device addressing is not required in broadcast mode, therefore commissioning is simpler and more cost effective. Also maintenance costs are greatly reduced using broadcast DALI as faulty drivers or ballasts are simply replaced with no computer intervention, unlike “Individual” and “Group” DALI where detailed knowledge of DALI programming is required to replace faulty drivers.
The DALI Broadcast module is connected to other eDIN+ or Evolution devices in a system by the MBUS network connection, which provides SELV communication between system devices. The system is orchestrated by the Network Processor (DIN-NPU-00-01) which is programmed via a computer. Alternatively for small systems with up to eight circuits the Dali Broadcast Module can be used with a control plate in “standalone mode” without the need for a Network Processor. In this case set-up is directly via the DIN-DBM’s on-board keypad and the control plate with no computer required (white fixtures only).
