Leviton Telcom OSSMT-GTI Vacancy Sensor

Product Description

The LEVITON TELCOM OSSMT-GTI is a multi-technology vacancy sensor designed for commercial and residential lighting control applications. Vacancy sensors require a manual-on activation and provide automatic-off functionality when occupancy is no longer detected, distinguishing them from standard occupancy sensors. Multi-technology sensing combines passive infrared and ultrasonic detection methods to reduce false-off events and improve coverage across a variety of room geometries. This type of device is typically specified and installed by licensed electricians as part of a lighting control or energy management system.

The OSSMT-GTI is suited for indoor environments where reliable occupancy detection is required, including offices, conference rooms, restrooms, and similar commercial spaces. Its multi-technology detection approach makes it appropriate for areas with mixed motion profiles, such as rooms where occupants may remain stationary for extended periods. Installation follows standard low-voltage and line-voltage wiring practices depending on the system configuration.

Key Features

• Multi-technology detection combining passive infrared and ultrasonic sensing for broad coverage
• Vacancy sensor mode requires manual-on activation, supporting energy code compliance in many jurisdictions
• Designed for indoor commercial and residential lighting control applications
• Single-unit quantity per package for individual installation or replacement

Compatibility

Designed as an OEM-style replacement or new-installation vacancy sensor for compatible LEVITON TELCOM lighting control systems. No specific compatible model numbers were provided in the available product data.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. Power to the circuit must be shut off at the breaker before beginning any wiring work. Follow the manufacturer wiring diagram for line-voltage or low-voltage connections as applicable to the system configuration. Do not exceed the sensor load rating when connecting lighting circuits.
