OSSMT

Decora

Wall Switch Multi-Technology

Occupancy Sensor

OSSMT-MD/GD

BASIC OPERATION

Occupancy sensors have two tasks: keeping the lights

ON while the space is occupied and turning the lights

OFF when unoccupied.

The Passive Infrared (PIR) sensors provide immunity

to false ON through a specialized Fresnel lens which

divides the field-of-view into sensor zones. When

a person passes into or out of a sensor zone, the

sensor detects motion and switches the lights ON.

The Ultrasonic (U/S) sensors provide maximum

sensitivity and range in difficult spaces with irregular

shaped rooms and partitions that can block the PIR

field-of-view. A pair of U/S sensors will detect Doppler

shifts caused by motion in a space preventing false

OFF. These sensors are more sensitive to small

movements since they do not rely on zones.

APPLICATIONS

The Leviton Decora

Wall Switch Multi-Technology

Occupancy Sensor (OSSMT) is used to provide

automatic lighting control for energy savings and

convenience in a variety of commercial applications:

• Retrofit

• Private and executive offices

• Conference rooms

• Storage areas

• Restrooms

• Classrooms

• Lounges

• Training areas

• Multi-location switching (similar to 3-way)

SELF-ADAPTIVE TECHNOLOGY

Designed for “install-and-forget” use, the OSSMT

automatically analyzes room conditions and adapts to

errors or changing environment.

HOW THE OSSMT-MD AUTOMATICALLY ADAPTS

CONDITION EXAMPLE ADAPTIVE REACTION

False-ON:

Sensor

incorrectly

turns the

lights ON

False-OFF:

Sensor

incorrectly

turns the

lights OFF

After an initial movement

is sensed, if another

movement is not sensed

within the timer setting the

delayed off-time setting is

automatically reduced

If motion is detected

shortly after the lights

go OFF, the current

delayed off-time setting is

increased

The sensor detects

movement in the

corridor or hallway

and the room light

turns ON

The sensor

does not detect

movement because

an occupant is

virtually motionless

and the lights turn

OFF

FEATURES • Fast, simple installation: fits in a standard wall box and replaces a single-pole wall-switch; neutral and no neutral options available. Sensor can be ganged together with other units in a multiple-switch wall plate. • Low-profile design eliminates obtrusive “scanningdevice” look. Elegant Decora wallplates complement any interior for sleek aesthetics; uses Decora wallplates and coordinates with Leviton’s popular line of Decora wiring devices.

INSTALLATION The OSSMT is preset to deliver optimum performance in a wide variety of applications without requiring any adjustments during installation. Exclusive self-adjusting operating features will automatically compensate for real-time occupancy patterns to provide maximum convenience and energy savings. The unit may replace a single-pole wall switch mounted in a standard wall box. The OSSMT-MD must have a neutral and be properly grounded in order to operate.
