Schneider Electric CCT551023 HF High Bay Presence Detector is a type of occupancy sensor or motion detector used in industrial or commercial settings. HF stands for"High Frequency. It refers to the use of microwave technology for detecting motion. Microwave sensors emit low-power microwave signals and measure the reflection of those signals. 

High bay areas have ceilings that are significantly higher than in standard commercial or residential buildings. Specialized sensors are often used in these areas due to their unique requirements. Presence Detector is designed to detect the presence of people or objects within its range. The detector can monitor two separate areas or zones. 

In summary, Schneider Electric CCT551023 HF High Bay Presence Detector is a motion sensor designed for high bay areas that use high-frequency microwave technology for detection. It has the capability to monitor two separate areas for presence or motion.
