PRODUCT DATA
OSSMD
FEATURES
• Provides automatic lighting control for two
separate banks of fluorescent, incandescent or
low-voltage lighting from a single unit
• The second relay is a manual-ON only with a
maximum 30 minute time-out for maximum
energy savings and complies with California Title
20/24
• Fits in a standard single-gang wall box and
replaces two single-pole wall-switches for fast and
easy installation; neutral and ground connection
required for OSSMD-MD. OSSMD-GD does not
require a neutral for installation.
• 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.
• 180° field-of-view provides approximately 2400
square feet of coverage, suitable for a variety of
commercial areas
• Convenient push buttons provide manual-ON/OFF
light switching of each load 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 tape required.
• Manual-ON/auto-OFF mode for installations where
manual-ON switching is required but auto-OFF
switching is still desired for California Title 20/24
energy savings
• To comply with California Title 20/24, the LED
indicator light flashes when the sensor detects
motion to verify detection is active. Green flashes
for ultrasonic, red flashes for PIR.
• Time delay adjustment for delayed-OFF time
settings of 30 seconds (for walking test), 10
minutes, 20 minutes and 30 minutes. Allows
customized adjustments to maximize energy
savings.
• Light sensor measures the ambient light in the
room when it first detects motion and leaves the
lights OFF (hold-off) if there is enough light in the
room or turns the lights connected to the first
relay ON if there is not enough light in the room
• Self-Adaptive technology eliminates callbacks for
adjustments. Time delay and sensitivity settings
are continually 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
• Non-Adaptive Mode disables self-adjusting
delayed-OFF time and walk-through feature in
applications where these feature are not desired.
Optional manual adjustment for delayed-OFF
time settings allows customized adjustments to
maximize energy savings.
• Vacancy confirmation; when the time out expires
and the relay turns OFF, a 30-second vacancy
confirmation exists to turn the relays back ON
• False detection circuitry
• U/S technology provides excellent minor motion
sensitivity
• Ability to disable PIR or U/S for added flexibility
• Presentation Mode feature for slide or film
presentations allows push buttons to turn lights
OFF and keep them OFF while the room is occupied
• Exclusive Leviton High Inrush Stability (H.I.S.)
Circuitry—specifically designed to handle today’s
high inrush electronic ballast loads and offer
unmatched durability and service
• One unit can be used for 120V-277V lighting
• Compatible with both electronic and magnetic
ballasts
• 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
