- Page 2 UNIT DESCRIPTION AND OPERATION The UW-100-24 Ultrasonic Low Voltage Wall Switch sensor employs 40kHz ultrasonic technology in a single-gang wall switch unit. The UW-100-24 sensor can turn a load ON, and hold it ON as long as the sensor detects occupancy. After no movement is detected for the selected time delay, the lights switch OFF.
- Page 3 SmartSet™ auto The sensor records typical occupancy patterns. Using this history (which is constantly updated), it chooses an adjust time delay optimal time delay from 7 minutes (if the space is and Test Mode usually vacant) up to 30 minutes (if the space gets heavy usage).
- Page 4 COVERAGE PATTERNS Coverage testing has been performed according to the NEMA WD 7 guideline. For best performance, use in spaces not larger than 15’ x 15’. Ultrasonic Sensor The sensor has two ultrasonic transceivers operating at 40kHz. Detection sensitivity can be adjusted using the trimpot under the ON/OFF buttons.
