The DUS804C-UP is a 360º ceiling surface mounted sensor that combines Ultrasonic (UP), Passive Infra-red (PIR) motion detection, ambient light level detection (PE) and infra-red remote control reception (IR) in the one device. In applications such as office buildings, lecture theaters, and homes, the DUS804C-UP universal sensor can be utilized to detect motion within its scan area to trigger a programed action with the lighting. When the DUS804 has detected a room is unoccupied for a set time, lights can be automatically dimmed or switched off to provide energy savings. The same sensor provides IR control reception to enable full remote control over lights, audio-visual equipment and blinds. A range of hand-held infra-red transmitters to complement series of universal sensors are available. In situations where it is critical to maintain precise lighting control for large workspaces such as open office floor plan, the DUS804C facilitates light compensation in an automatic“ Daylight Harvesting” mode for energy savings.
