DIMENSIONAL DIAGRAMS
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 “scanning-device”
look. Elegant Decora wallplates complement any interior
for sleek aesthetics; uses Decora wallplates and coordi-
nates with Leviton’s popular line of Decora wiring devices.
• Convenient Pushbutton provides manual-ON/OFF light
switching at any time.
• Segmented Fresnel lens provides optimum sensitivity
and performance. Designed with an extensive “minor
motion” area where even slight body movements will be
detected.
• Vandal resistant PIR lens.
• Patented Blinders: Adjustable horizontal field-of-view (PIR
may be adjusted between 180° and 60° of arc by using
integral blinders located on either side of the lens). No
masking required.
• Manual-ON/auto-OFF mode for installations where manu-
al-ON switching is required but auto-OFF switching is still
desired for CEC Title 24 energy savings.
• To comply with CED Title 24, LED indicator light flashes
when sensor detects motion to verify detection is active.
Green flashes for ultrasonic, red flashes for PIR.
• Time: The delayed OFF time is preset at 30 minutes in
the Auto Adapting mode. A choice of four delayed-OFF
time settings are available: 30-seconds (for walking test
purposes only), 10, 20, and 30 minutes for fixed time and
auto adapting. The LED will flash when the adjusting knob
is set to the indicated time value.
• Ambient Light Recognition: Integrated light sensor pre-
vents lights from turning on when the room is adequately
illuminated by natural light.
• Self-Adaptive Technology: Callbacks for adjustment are
eliminated. Time delay and sensitivity settings are con-
tinually adjusted to occupant patterns of use in auto
adapt mode.
• Exclusive Walk-through Feature provides increased
energy savings by not leaving the lights ON for an
extended period after only momentary occupancy.
• Vacancy Confirmation: When the time out expires and
the relays turn OFF, a 30 second (OSSMT-G) or 40 second
(OSSMT-M) vacancy confirmation exists to turn the relays
back on.
• False detection circuitry.
• Small Motion Sensitivity (U/S): Ultrasonic technology pro-
vides excellent minor motion sensitivity.
• Ability to disable U/S (OSSMT-M). For added flexbility,
OSSMT-G has the ability to disable both PIR and U/S.
• Presentation Mode feature: For slide or film presenta-
tions, allows pushbuttons to turn lights OFF and keep
them OFF while the room is occupied.
• Exclusive Leviton H.I.S. Circuitry. Specifically designed to
handle today’s high inrush electronic ballast loads and
offer unmatched durability and service.
• True Zero-Cross Relay switches at the zero crossing point
of the AC power curve to ensure maximum contactor life
and compatibility with electronic ballasts.
FIELD-OF-VIEW
The OSSMT provides a 180° field-of-view with a maximum
coverage area of approximately 2400 square feet. The
maximum sensing distance in front of the sensor is 40
feet, and side to side is 30 feet. The “minor motion” zone
detects relatively small body movements and allows the
lights to stay ON even though a person may not be moving
or walking around the room. The remainder of the field-of-
view, the “major motion” zone, exhibits a lesser degree of
sensitivity and requires larger movements.
