LRD‑309S Series

Line Voltage SmartDIM Occupancy Sensor

The LRD‑309S is a low profile, fixture integrated occupancy sensor designed to control 0‑10V dimmable ballasts and LED drivers. This two‑way IR remote programmable sensor is capable of providing four different occupancy sensing control schemes with fully adjustable multi‑level high/low StepDIM or SmartDIM control to the integrated fixtures.

This sensor comes with a compact body design and can be easily integrated with luminaires through a 1.34" hole. The LRD‑309S series are available with interchangeable lenses.
