DALI lighting control integrates with existing BMS at Imperial College London
The new DALI lighting system at Imperial College London is controlled by LiGO controllers from Open Technology with virtual TrendIQ built into them. This enables them to be controlled by the existing Trend 963 system, with control of the lighting and the receiving of alarms and notifications being handled as if the LiGO were a Trend IQ system. Even the graphs of lighting levels and PIR profiles are displayed on the 963 system.
There has been no need to retrain operators, and lighting can be maintained and operated from the same PC as the BMS. A LiGO controller provided details on consumption through its built-in analytics feature. The LiGO system also integrates with the Creston equipment controlling the audio-visual equipment in the teaching spaces and a lecture theatre.
A LiGO controller can serve eight DALI networks of 64 points each. It has an embedded web server and Ethernet connectivity. The PIR signal that is used to control lighting according to occupancy is also available to the BMS to control other services such as air conditioning.
This project has two LiGO panels. Open Technology’s engineers designed and commissioned the system under contract to Gratte Brothers.
