OSSMT-TM/GT
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
coordinates with Leviton’s popular line of Decora wiring
devices.
• Convenient push button 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
• 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 vacancy sensor for installations
where manual-ON switching is required but auto-OFF
switching is still desired
• 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 .
• Self-adaptive technology: callbacks for adjustment
are eliminated. Time delay and sensitivity settings are
continually adjusted to occupant patterns of use in auto
adapt mode.
• Vacancy confirmation: when the time out expires and
the relays turn OFF, a 30 second vacancy confirmation
exists to turn the relays back on
• False detection circuitry
• Small motion sensitivity (U/S): ultrasonic technology
provides excellent minor motion sensitivity
• Ability to disable U/S (OSSMT-TM). For added flexibility,
OSSMT-GT has the ability to disable PIR or U/S
• Exclusive Leviton 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
• Non-volatile memory: after power loss, product returns
to last state
FIELD-OF-VIEW
The OSSMT provides a 180° field-of-view with a maximum
coverage area of approximately 2,400 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.
