The SWITCHLITE MRE SLD 2CH recessed PIR Presence Detector provides energy saving (on/off switching) in response to room occupancy and daylight levels, controlling lighting loads with optional manual control. The detector provides two independently controlled output channels that can be used for a variety of applications. • Occupancy of two independent lighting circuits using a single detector, e.g. for essential and non-essential supplies. • Occupancy and lux control of one lighting circuit and just occupancy control of a second circuit, e.g. where a row of luminaries by a window is lux controlled whilst inner rows are switched on occupancy only. • Occupancy and lux control of a lighting circuit and just occupancy control of a ventilation circuit. • Occupancy on both lighting circuits, with separate lux control on each circuit.
