Hochiki Europe sensors are contributing to the aesthetic standards that have become the hallmark of the recently redeveloped St Pancras International Station in London. To maintain the design integrity of the ceiling throughout The Circle - one of the key retail areas in the station - the company has supplied black sensors that are housed in black-lined accent lighting troughs and are virtually indiscernible to the casual observer. To ensure the operational effectiveness of the sensors, each is located on a stalk that lowers the sensor to ceiling level.
