Wall Mounted Dual Technology Occupancy Sensors employ both passive infrared (PIR) and ultrasonic technology to accurately detect occupancy and automatically turn on lighting.
To reduce the occurrence of false on events, this sensor uses PIR technology to detect major motion. Once lighting has been turned on, it employs highly sensitive PIR and ultrasonic technology to detect minor motion and keep lighting on while areas remain occupied. When the room or area is no longer occupied, the sensor turns off lighting after a pre-set time delay.
Wall Mounted Dual Technology Occupancy Sensors also incoporate an integral light level sensor to prevent lighting from switching On when sufficient ambient light is present, such as is commonly found in windowed areas.
