Leviton Telcom OSSMD-MDT Wall Box Occupancy Sensor

Product Description

The LEVITON TELCOM OSSMD-MDT is a wall box occupancy sensor designed for automatic lighting control in commercial and residential applications. It operates at dual voltage, supporting both 120 volts and 277 volts, making it compatible with a wide range of electrical systems. The sensor detects occupancy within a space and switches lighting loads on or off accordingly, reducing energy consumption and eliminating the need for manual switching. Licensed electricians typically handle installation in standard wall box locations during new construction or retrofit projects.

This occupancy sensor is suited for offices, conference rooms, restrooms, storage areas, and similar spaces where automatic lighting control is required. The dual-voltage design allows deployment across both standard 120-volt branch circuits and commercial 277-volt lighting circuits, reducing the need to stock separate sensors for different voltage environments. It ships as a single unit and is intended for permanent wall box mounting.

Key Features

• Dual-voltage operation at 120 volts and 277 volts for flexible installation across circuit types
• Wall box mount design integrates into standard single-gang electrical boxes
• Automatic occupancy detection switches lighting loads without manual intervention
• Sold as a single unit for individual zone control

Compatibility

Designed as an OEM-style replacement or new-installation wall box occupancy sensor for standard single-gang electrical boxes on 120-volt or 277-volt lighting branch circuits.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements. De-energize the circuit at the breaker panel and verify absence of voltage before wiring. Follow the manufacturer wiring diagram included with the unit and ensure the wall box is properly grounded before completing the installation.
