Watt Stopper Ultrasonic Sensors are 24VDC switching gadgets that instantly switch lighting and HEATING AND COOLING systems off when no motion is noticed over a provided time period. They pick up when a location is inhabited and turn lights back on again. Watt Stopper ultrasonic occupancy sensing units utilize the doppler shift principle to discover occupancy. Motion in the controlled location causes a slight change in the shown frequency and amplitude of the broadcast ultrasonic waves. Watt Stopper sensors then manage lighting systems through Watt Stopper power and auxiliary relay packs. Placement of the sensor is important for correct operation. Watt Stopper sensors are volumetric sensors and sense motion in a 360 degree pattern. It is best to put the sensing unit so that it has a clear view of all the desktops or work surface areas within the protection area. Likewise, ultrasonic sensors might false-trigger when challenged by high volumes of air circulation. Sensors ought to be set up a minimum of 4 feet from the majority of supply ducts and a minimum of six feet from horizontal discharge ducts. In addition, do not install sensing unit within 6″ of power pack. Always install the sensing unit on a rigid, vibration-free surface area. When placing the sensing unit ensure the receiver is aimed far from closest wall and towards area to be covered.
