Occupancy Sensors
A series of wall-mounted occupancy detectors designed to switch Douglas 2-wire relays or to signal other systems
Several dual-technology models are available that both measure PIR (passive infrared radiation) generated by motion and detect sounds typical of human activity
Combining PIR and sound detection allows the dual-technology units to sense occupancy through obstructions in all directions across a 180 degree arc
The dual technology units are available with 1 or 2 outputs (poles)
The dual-technology units are suitable for smaller rooms with obstructions such as an office or a bathroom with partitions
A PIR-detection-only model, the
WSD-W-DL
, is suitable for smaller rooms without obstructions
All units connect like a 2-wire switch
All units have programmable switching modes and adjustable time delay
