The low-cost approach to presence-controlled lighting

Presence-controlled lighting can be provided using standard low-cost components with TridonicAtco’s corridorFUNCTION. Standard presence detectors and luminaires with PCA T5 ECO lp and PCA T5 EXCEL one4all lp control gear is all that is required to provide presence-controlled lighting, particularly in rooms with no daylight, such as underground garages and warehouses. The corridorFUNCTION eliminates the need for a separate controller using the switchDIM input terminal and can be programmed so that if no-one is in the room, the lighting is not switched off, as is the case with non-dimmable control gear, but dimmed. It can then be switched off automatically after a preset delay. The corridorFUNCTION enables any number of presence detectors and luminaires to be connected in parallel. Long corridors or large areas such as underground garages can be simply connected and yet well lit.
