Greengate’s OSW-DT-0601-MV-W Dual Tech-PIR Wall Switch Sensor combines ultrasonic and Passive Infrared (PIR) sensor technology to monitor a room for occupancy to deliver unrivaled performance and reliability. The PIR is used to detect motion and turn lights on, while either technology is used to keep lights on while occupied. This allows the Ultrasonic to be set to higher sensitivity levels minimizing false off conditions. The PIR portion gives immunity to false on conditions through a specialized lens which divides the field of view into sensor zones. When a person passes into or out of a sensor zone, the sensor detects motion and switches the lights on. The Ultrasonic sensors give maximum sensitivity and range in difficult spaces with irregular shaped rooms and partitions that can block the PIR field of view. The Ultrasonic sensors will detect Doppler shifts caused by motion in a space. These sensors are more sensitive to small movements since they do not rely on zones. The sensitivity can be field adjusted to low, medium, and high. This feature makes the OSW-DT-0601-MV-W perfect for a wide variety of room sizes and configurations. The OSW-DT-0601-MV-W Dual Tech-PIR Wall Switch Sensor is used to provide automatic lighting control for energy savings and convenience in a variety of commercial applications. It provides for automatic switching of incandescent lamps, low voltage lighting with electronic and magnetic transformers, and electronic and magnetic fluorescent ballasts. The OSW-DT-0601-MV-W features a manual override switch that can be used to keep lights on while an area is occupied, which may be desired in conference rooms, classrooms and other areas during video presentations. Designed to replace a single pole decorator wall switch, it fits in a standard wall box, and can be ganged together with other units in a multiple switch wall plate. The unit requires a neutral and a ground connection.
