The manlock also provides would-be victims a view of SY3's co-location hall 2 via a huge viewing window. The hall is mostly vacant at the moment, with a single customer currently residing there.
LED lights illuminate the hall in a blue glow when no one is working in it, switching to conventional lighting once sensors detect that someone has entered in order to conserve energy. It is a similar set up that exists at SY2. The power distribution units either side of the hall are colour-coded according to their function. Grey represents primary power, while orange represents redundant.
