From the Manufacturer Occupancy sensors have two tasks: 1) Keeping the lights ON while the room is occupied and 2) Saving energy by keeping the lights OFF while the room is unoccupied. OSCxx-RMW sensors combine the benefits of both PIR and U/S technologies for unrivaled performance and reliability. Additionally the sensor is designed with an isolated relay contact; which enables the sensor to interface with other systems (example: BAS HVAC or any dry-contact capable device or system).
