MS1500 Ultrasonic Series


Standard Series LightSpot is a general purpose, fully automatic, directional presence detector with photocell. It saves energy by switching off lights in unoccupied areas and by holding lights off in occupied areas, which have adequate natural light. It uses a specially developed ultrasonic radar to monitor the controlled space for movement. This radar is sensitive enough to respond to even very small movements thus ensuring that lights are sustained whenever the controlled space is occupied. If no movement has been detected for a pre-selected period, LightSpot switches the lights off until the next visitor is detected.
