Leviton Telcom OSSMT-GTT Vacancy Sensor

Product Description

The LEVITON TELCOM OSSMT-GTT is a multi-technology vacancy sensor designed for commercial and residential lighting control applications. Vacancy sensors require manual activation of lights and automatically turn lights off when no occupancy is detected, making them a code-compliant alternative to standard occupancy sensors in certain jurisdictions. The OSSMT-GTT combines multiple detection technologies to reduce false-off events and improve reliable coverage in a variety of room configurations. Licensed electricians and lighting control technicians are the typical installers of this device.

This vacancy sensor is suited for office spaces, conference rooms, private offices, restrooms, and similar interior environments where manual-on control is required by energy codes such as ASHRAE 90.1 or local amendments. The unit ships as a single device per package and is intended for wall-box installation in standard single-gang or compatible enclosures. Its multi-technology detection helps cover areas where a single passive infrared or ultrasonic sensor alone may leave dead zones.

Key Features

• Multi-technology detection reduces false-off events compared to single-technology sensors
• Vacancy mode requires manual-on activation for energy-code compliance
• Single-device package suitable for individual room installations
• Wall-box mount design for straightforward low-voltage wiring integration

Compatibility

Designed as an OEM-style replacement or new-installation vacancy sensor for standard wall-box lighting control systems. No specific compatible model numbers or system families were provided in the product data.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements for low-voltage control wiring. De-energize the circuit at the breaker panel before wiring or replacing the sensor. Follow the manufacturer wiring diagram for line, load, and neutral connections. Do not exceed the sensor load rating for the connected lighting circuit.
