Watt Stopper Ultrasonic Sensors are 24VDC switching gadgets that automatically change lighting and HEATING AND COOLING systems off when no motion is noticed over a provided period. They notice when a location is inhabited and turn lights back on again. Watt Stopper ultrasonic occupancy sensing units use the doppler shift principle to detect occupancy. Movement in the regulated location triggers a small modification in the shown frequency and amplitude of the broadcast ultrasonic waves. Watt Stopper sensors then control lighting systems through Watt Stopper power and auxiliary relay packs. Positioning of the sensor is crucial for correct operation. Watt Stopper sensors are volumetric sensors and sense motion in a 360 degree pattern. It is best to put the sensor so that it has a clear view of all the desktops or work surfaces within the coverage area. Likewise, ultrasonic sensing units may false-trigger when confronted by high volumes of air circulation. Sensing units ought to be installed a minimum of 4 feet from the majority of supply ducts and a minimum of 6 feet from horizontal discharge ducts. In addition, do not mount sensing unit within 6″ of power pack. Always mount the sensor on a rigid, vibration-free surface area. When positioning the sensing unit make certain the receiver is intended away from nearest wall and towards location to be covered.
