Occupancy switch

Two Batten-mounted PIR occupancy switches from Danlers are said to be capable of achieving energy savings of up to 50%, keeping the payback period to a minimum.

UK-manufactured, the IP53 rated controls can switch lighting loads of up to 10A and can be mounted onto the end of lighting battens. They detect the movement of a warm body within their detection zones (either 5 or 10m variants) and include a photocell which can be set to between 100 and 3000 lux. A realtime photocell status indicates if the photocell is active or inactive. Its calibration process can distinguish between artificial and natural light.
