W-2000A WattStopper 360 Degree Ultrasonic Motion Ceiling Occupancy Sensor, 24V Watt Stopper


(as of 10/22/2018 at 15:02)

Product Description

Watt Stopper Ultrasonic Sensors are 24VDC changing gadgets that immediately change lighting and HVAC systems off when no motion is sensed over an offered time period. They notice when an area is inhabited and turn lights back on again. Watt Stopper ultrasonic occupancy sensing units use the doppler shift principle to identify occupancy. Movement in the controlled area causes a minor modification in the shown frequency and amplitude of the broadcast ultrasonic waves. Watt Stopper sensing units then control lighting systems through Watt Stopper power and auxiliary relay packs. Positioning of the sensing unit is vital for proper operation. Watt Stopper sensing units 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 protection location. Likewise, ultrasonic sensing units might false-trigger when challenged by high volumes of air circulation. Sensing units need to be installed a minimum of four feet from the majority of supply ducts and a minimum of 6 feet from horizontal discharge ducts. In addition, do not mount sensor within 6″ of power pack. Always install the sensing unit on a rigid, vibration-free surface area. When placing the sensing unit make sure the receiver is intended far from nearby wall and toward area to be covered.
