PRODUCT DATA
OSSMD
FEATURES
• Provides automatic lighting control for two sepa-
rate banks of fluorescent, incandescent, or low-
voltage lighting from a single unit.
• The second relay is a manual-ON only with a maxi-
mum 30 minute time-out for maximum energy sav-
ings to comply with CEC Title 24
• The OSSMD-FT is intended to control a light circuit
and a fan. The button on the sensor provides ON
control for both circuits and OFF for lighting circuits
only. The sensor will automatically turn ON both
when occupancy is detected. When no movement
is detected, the primary relay will turn OFF after the
delay OFF time expires. The fan will remain ON to
clear the airspace for an additional 10 minutes after
the time-out or button press.
• 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 and OSSMD-FT. OSSMD-GD does not
require a neutral for installation.
• Low-profile design eliminates obtrusive “scanning-
device” look. Elegant Decora wallplates comple-
ment 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 pushbuttons provide manual-ON/OFF
light switching of each load at any time.
• Segmented Fresnel lens provides optimum sensitiv-
ity and performance. Designed with an extensive
“minor motion” area where even slight body move-
ments 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 CEC Title 24 energy
savings.
• To comply with CEC Title 24, LED indicator light
flashes when sensor detects motion to verify
detection is active. Green flashes for ultrasonic, red
flashes for PIR.
• Time delay adjustment for delayed-OFF time set-
tings 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 applica-
tions 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 con-
firmation 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 presen-
tations allows pushbuttons 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 through 277V light-
ing. 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.
