The DUS804C is a low profile recessed flush mount 360o ceiling mount sensor that combines motion detection (PIR), Infra-red remote control reception (IR) and ambient light level detection (PE) in the one device. In applications such as office buildings, lecture theaters and homes, the DUS804C universal sensor can be utilized to detect motion and switch on the lights. When rooms are unoccupied, lights can be automatically dimmed or switched off to provide energy savings. The unit also incorporates a segmented click-up bezel surrounding the motion sensor element. This enables a portion of the sensing field to be readily masked to prevent nuisance detection from adjacent doorways or corridors. 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 DUS804 series universal sensors are available. In situations where it is critical to maintain precise lighting control for individual workspaces, such as an office workstation or even air traffic control centers, the DUS804C facilitates light compensation. The DUS804C can also be placed in an automatic “Daylight Harvesting” mode for energy savings.
