2. Leviton Exclusive Leviton Advantage

3. MULTI - TECH Sensor Technology Passive Infrared (PIR) Ultrasonic (US)
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

10. Field of View (FOV) Major Motion vs. Minor Motion FOV for WSC04, OSC04
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

11. 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

12. PIR Masking - Leviton Advantage

13. 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

14. 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)

15. 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.

16. 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
Occupied Operational Test Mode
Perimeter Walk Test Mode

17. Application & Design Tool

32. 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

33. 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

34. 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 auto-adjust the U/S sensitivity to compensate for air flow to prevent false-ON 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
