Leviton OSSMD-MDW Installation guide

Brand: Leviton

Model: OSSMD-MDW

Type: Installation guide

Leviton OSSMD-MDW is a multi-technology wall switch occupancy sensor with dual relays, designed for commercial and residential applications. It combines passive infrared (PIR) and ultrasonic (US) sensing technologies to provide accurate and reliable motion detection. The device offers multiple modes of operation, including auto ON and manual ON, and can be configured to control two separate lighting circuits from a single unit.

Key Features of Leviton OSSMD-MDW:

Dual-Technology Sensing: Utilizes both PIR and US sensors for enhanced motion detection, ensuring reliable performance in various environments.
