Leviton Telcom OSSMT-MAW Wall Mount Occupancy Sensor

Product Description

The LEVITON TELCOM OSSMT-MAW is a wall-mount occupancy sensor designed for automatic lighting control in commercial and residential applications. Operating across a wide voltage range of 120 to 277 volts AC with a neutral wire connection, this sensor detects occupancy and triggers connected lighting loads without manual switching. It is sold as a single unit and is typically installed by licensed electricians performing lighting control upgrades, energy-code compliance retrofits, or new construction wiring.

The OSSMT-MAW suits wall-box installations where passive infrared or multi-technology detection is required to meet energy codes such as ASHRAE 90.1 or local jurisdiction lighting control requirements. It is appropriate for offices, corridors, classrooms, restrooms, and similar occupied spaces where automatic shutoff is needed to reduce energy consumption. The neutral wire requirement makes it compatible with standard commercial wiring configurations that include a neutral conductor at the switch location.

Key Features

• Wide voltage range: 120 to 277 volts AC accommodates commercial and residential circuits
• Neutral wire connection supports reliable operation across supported voltage range
• Wall-mount form factor fits standard single-gang or compatible wall boxes
• Automatic occupancy-based lighting control reduces manual switching
• Sold as individual unit for single-location installation or multi-point projects

Compatibility

Designed as an OEM-style replacement or new-install occupancy sensor for wall-box lighting control applications requiring 120 to 277 volt AC operation with a neutral conductor.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Power to the circuit must be shut off at the breaker panel and verified de-energized with a meter before wiring. Confirm that a neutral conductor is available at the wall box before installation, as this sensor requires a neutral connection. Follow the manufacturer wiring diagram for line, load, and neutral terminations.
