Expansion leads
Where an Expansion Unit is required to be remote from its preceding unit, plug them together via an Expansion Lead. For example you may wish to keep all the luminaire leads short along a corridor by using more than one unit linked together via Expansion Leads. Expansion Leads also offer the perfect opportunity for Expansion Units to become part of an interconnection system radiating from a Hub Unit – particularly ideal for the distribution of intelligent control from a central source (i.e DALI bus).
