360° Dual-Technology Ceiling Sensor:</br> Utilizes the benefits of advanced passive infrared (PIR) and ultrasonic technologies to provide 360-degree accurate occupancy detection. </br></br> Open Office Area Coverage</br> To get complete coverage in an open office area, install multiple sensors so that there is an overlap with each adjacent sensor’s coverage area. </br></br> Where to Install</br> The ceiling sensor is designed to be mounted about 8-10 feet off the ground. The implementation of two sensing technologies in each unit helps to avoid false triggering while still accurately sensing motion. </br></br> Fresnel Lens</br> The MDC-50V has multi-level, 360° Fresnel lens for superior occupancy detection with 6 detection options for users to trigger the ON function. The sensor can be set to require both PIR and Ultrasonic sensor detection simultaneously or either prioritize detection with either PIR or Ultrasonic sensing motion. </br></br> Important</br> This ceiling sensor is operated on 24V supplied by Enerlites MPP-24 Power Pack. Mounted on the ceiling of any office or warehouse area, the sensor should be set back from door openings to avoid detecting people passing by, and should stay 4 feet to 6 feet away from air supply ducts to avoid false activation. </br></br> Features</br></br> Time delay options: default 5 sec set, 30 sec, 5min, 10 min, 15 min, 20min, 25 min and 30 min.</br> PIR adjustment: 50% or 100%</br> The range coverages 1600 sq. ft. for PIR and 1000 sq. ft. for ultrasonic sensor.
