LSI Lighting OS-XXC-M-WH Multi-Technology Ceiling Occupancy Sensor
Product Spec Sheet
Passive Infrared (PIR) is an excellent and precise technology for initially turning the lights ON, but lacks sensitivity for minor motion at distances. Ultrasonic (U/S) technology provides maximum sensitivity with continuous reflective high frequeny waves. This is opitmal for keeping the lights ON. The multi-technology sensor combines the benefits of both PIR and U/S technologies for unrivaled performance and reliability.
