LSI Lighting OS-12W-M-WH Multi-Technology Wall/Corner Occupancy Sensor
Product Spec Sheet
Passive infrared technology is an excellent and precise sensing of motion for turning the lights on, but lacks sensitivity for minor motion at distances. Ultrasonic (U/S) technology provides maximum sensitivity with continuous reflective high frequency waves. This is opitmal for keeping the lights on. The OS 12W M combines the benefits of both PIR and U/S technologies for unrivaled performance and reliability.
