  3. MULTI - TECH SensorTechnology • 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

  4. Ultrasonic Multi-Tech +47 % +17 % MULTI - TECH Technology Cost Comparison This is why it is important to understand sensor technologies and applications. PIR Lowest Cost Sensor Heads Only – 1000 SF Coverage

  5. Low Voltage Ceiling Sensors Technology and upgrading – it is important to understand sensor technologies and applications for layout design and operation. PIR Ultrasonic Multi-Tech OSC05-U OSC10-U OSC20-U OSC05-M OSC10-M OSC20-M OSC04-I OSC15-I Sensor Head Coverage – 150, 500, 1000, 1500 or 2000 SF

  6. Low Voltage Wall Mount/Corner Sensors OSWHB-I0W OSWWV-I0W OSWLR-I0W OSW12-M0W

  7. Power Base Adaptor Combine Power Base Adaptor with any Leviton low voltage sensor for a Leviton stocking advantage. Patented

  8. 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 OSC04-RIOSC15-RI OSC05-RMOSC10-RMOSC20-RM OSC05-RUOSC10-RUOSC20-RU OSW12-RM OSWWV-RIOSWHB-RIOSWLR-RI

  9. Low Voltage Sensors • Field of View • PIR Masking • Time Delay • Sensitivity • Photocell • Auto Adapt for both Time Delay and US • Walk-Through • Field Configurable • Walk Test

  10. 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

  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 withAuto 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 OccupiedOperationalTest Mode Perimeter Walk Test Mode

  17. 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!

  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
