MULTI
- TECH
Passive Infrared (PIR)




Sense difference in heat emitted by humans in motion from background
Detect motion in a field of view that requires line of sight
Cannot see through obstacles
“FALSE OFF” is the biggest concern
Ultrasonic (US)




Uses Doppler – transmits ultrasonic frequencies (32kHz – 40kHz) and monitor
changes in the return signal in order to detect occupancy
Not a “line of sight” device since the transmitted sound signals can bounce or wrap
around objects
No gaps, greater sensitivity, but more vulnerable to nuisance switching
“FALSE ON” is the biggest concern
Multi-Technology (MT)



Passive infrared (PIR) and Ultrasonic (US) together
Advantage : PIR turns the lights ON & US keeps them ON
Eliminates the false OFF history of PIR and mitigates the false ON tendencies of US

Low Voltage Sensors with Isolated Relay




Isolated relay allows for direct connection to the BAS or HVAC system
Multiple voltages 24VAC/VDC allows for the sensor to pull power directly
from AC designs control systems
Multiple mounting heights allow for today’s vaulted ceiling and open
architecture style
 Leviton advantage – OSC models include both 8-12ft lens and
additional 12-20ft “mid-range” lens
True white color blends with today’s daylighting trends
 Existing off-white sensors are color blend matched with shaded
ceiling spaces and ceiling tiles

 Field of View
 PIR Masking
 Time Delay
 Sensitivity
 Photocell
 Auto Adapt for both Time Delay and US
 Walk-Through
 Field Configurable
 Walk Test
Field of View (FOV)
Major Motion vs. Minor Motion
 Correct selection of sensors and the FOV is
essential for optimal occupancy sensor
operation.
 Major Motion is large side to side movement
 Minor Motion is typing or conversational
movement
 Passive Infrared (PIR) sensor with a 360 degree
field-of-view (FOV) capable of monitoring and
area up to 450 square feet. The sensor will
detect Major Motion up to 12 feet from the
sensor (24ft diameter) and Minor Motion up to
6.5 feet (13ft diameter).
 Each FOV must be matched to the ROOM
USAGE.
 Example:
OSC04 is better for minor motion
applications (See chart Diagram 1)
OSC15 is better for major motion
applications (bigger is not always better)
FOV for WSC04, OSC04
Dark Gray = Minor Motion
Light Gray = Major Motion
Field of View (FOV)
Mounting Height Effect on FOV
 Low voltage sensors are ideal for control of any
fluorescent fixture mounted 8-10’
 FOV narrows at lower heights
 Detection zones are precise at lower heights
 OSC04 can be mounted higher is major motion
application
PIR Masking - Leviton Advantage
Photocell






Photocell – Ambient Light Hold OFF
Holds lights off unless natural light falls below a user selected level
DOE indicates an average of 46% savings can be achieved when
photocells are used in combination with occupancy sensors
Photocells come standard with Leviton sensors
Reality – market has not accepted or understood Ambient Light Hold OFF
Ambient Light Hold OFF is NOT daylight harvesting
Auto-Adapt



Auto Adapting or Self Adjusting - most efficient for energy savings
 Sensor has a built in adapting intelligence that changes the adapting time-out
duration in response to the occupancy conditions of the room it is installed in
Adjusts ultrasonic sensitivity (air flow) – Leviton Advantage
 decreases sensitivity when consistent U/S triggering is occurring to prevent
false ON’s and unwanted energy use
 increases sensitivity when false OFF occurs to counter end user complaints
for lights turning OFF
Reduces time-out duration (energy)
 initializes with 2.5 minute walk-thru time delay auto-adapt uses this time delay
even if walk-thru is not enabled. To enable walk-thru for additional savings, A4
dip switch must be in OFF position.
 is decreased when no secondary motion is detected within 2 minutes of
initializing this is a decrease by intellectual algorithm within firmware (7 day
history in memory)
 (after 2.5 min) reverts to configured time delay which could be the adjustment
dial time delay or a calculated auto-adapt time delay
 increases when lights OFF (false off) occurs and motion is detected within 30
seconds this is an increase by intellectual algorithm within firmware (7 day
history in memory)
Walk-Through


Adaptive Walk-Through
When the lights turn on, the sensor initially enters the “Walk-Through”
mode. Once the room is occupied for longer than 2.5 minutes, the sensor
exits the “Walk-Through” mode and enters the “Occupied” mode.
Walk Test - Leviton Advantage


Built in testing modes enable the
installer to fine tune sensors faster
than any other sensor on the market
Occupied Operational Test Mode


By using the dip switch B3, an
installer can enter a 15 min test
mode with Auto Exit (Leviton
Advantage) where the sensor will
Auto-ON/Auto-OFF every 15 sec.
This is for testing the room use
specifics (occupied sensitivity) to
assure the lights will not shut off
on a single occupant in a specific
location
Perimeter Walk Test Mode

By reducing the time delay dial to
30 sec, the installer is able to test
the true perimeter of the FOV
(unoccupied sensitivity) for entry
points and/or total FOV coverage

Application & Design Tool
Select Coverage Pattern
 Partition larger spaces into control zones, with one sensor/zone
 Ensure coverage overlaps by 20%
 If partitions >48 in. high, de-rate sensor range by 50%
 Don’t reduce the optimal number of sensors!

Wall Switch Sensors - Leviton Advantages



Exclusive Dual Pyrometers (PIR) Sensors
 Provides for largest Field of View, 40’x40’, 180 degrees
 2x as many detection points and best in class minor motion
Vandal Resistant PIR Fresnel Lens
 Dual Pyros allow for thicker lens, smaller profile lens and re-enforced
bridge to support the lens which prevents the sensor from being
poked, tampered-with or damaged
Multi-Technology Sensing
 Combination of PIR and ultrasonic (U/S) sensing
Wall Switch Sensors - Leviton Advantages




Internal Photocell
 Standard in Leviton sensors, the internal photocell prevents lights
from turning on when there is ample natural light. The result, ambient
light hold-off which maximizes energy savings in a low cost device.
Field Configurable to Single Tech (on select models)
 OSSMD models can be configured to become a single tech device by
turning off the PIR or U/S. This allows the sensor to be modified to fit
the unique needs of an application while in the field
Field of View and PIR Masking
 Switches designed for multiple points of view: sensors range from 20
to 40 feet of coverage, allowing customers to tailor an occupancy
sensor plan to their specific needs
 PIR Masking: patented blinders allow for customized blocking of
false-ON sensing areas (adjacent hallways, etc.) so loads only
activate when necessary, preventing unnecessary energy
consumption
Presentation Mode - Manual-OFF occupant override
Wall Switch Sensors - Leviton Advantages


H.I.S (High Inrush Stability)
 Zero-Crossing
 Mechanically Held Relay
 Return to last state (Latching)
 Safety and energy savings
Self-Adaptive Technologies
 Reduced time-out durations: optimize energy savings. Sensors autoadjust the U/S sensitivity to compensate for air flow to prevent falseON from HVAC
 Walk-Through: adapts the time-out duration of the sensors in
response to the most common occupancy conditions of the room it is
installed in to guarantee the sensor best meets the customer’s needs
 Walk Test: To verify a correct field of view, a walk test is completed by
installer walking around the perimeter of the coverage pattern, which
allows the PIR technology to divide the area into “detection zones.”
This initial test improves sensor performance and reduces labor and
maintenance associated with returning to adjust the sensors
