Wasted lighting energy is the problem

Lighting can account for up to 50% of your
building’s total energy use. Many building
spaces remain unoccupied with the lights
on for 40% to 70% of daily operating hours,
wasting energy and money.

Lutron occupancy sensors are the solution

Lutron’s full line of occupancy sensors automate
the switching or dimming of the lights, reducing
the energy wasted in unoccupied spaces.

| benefits of using occupancy sensors

Reduced energy costs

Lutron occupancy sensors reduce energy consumption in building
spaces by automatically shutting off the lights in unocuppied spaces.

Using Lutron occupancy sensors can eliminate 20% – 30%

of lighting energy costs.

Convenience
You never have to worry about turning on or off the lights.
Lutron occupancy sensors automatically turn them on
and off when you enter or exit a restroom, a classroom,
a conference room, a hallway, or your office.

Obtain LEED™ certification points

LEED™ is a voluntary rating system sanctioned by
the United States Green Building Council (USGBC)
that provides a national guideline for what constitutes
a “green” building. Efficient lighting controls may
contribute to obtaining up to 22 points in 5 of 6 LEED™ credit
categories. A minimum of 26 points is required for Leadership in
Energy and Environmental Design certification. Lutron occupancy
sensors help you meet the requirements for these certification points.

Comply with building energy codes

Energy codes play a key role in helping us reduce our energy
consumption. They set the mandatory performance requirements
for building construction. Most commercial energy codes have
mandatory requirements that can be cost-effectively and
conveniently met with the use of Lutron occupancy sensors.

Maintain fluorescent lamp life

When occupancy sensors turn off fluorescent lamps many
times a day, the expected long lamp life is cut by up to 50%.
If the occupancy sensor turns the lamp to 10% light output
instead of completely off, the lamp life is unaffected.

Safety and security settings

Keep the lights on to a minimum level when the
space is unoccupied for added security and safety.

Flexibility
Easily reassign the lights that are controlled by
a particular occupancy sensor without rewiring.

self-adaptive technology

Typical occupancy sensors require manual adjustment

of time and sensitivity settings to avoid false triggering.
By analyzing occupancy patterns, Lutron self-adaptive occupancy
sensors constantly update their time and sensitivity settings to
ensure that the sensors have the greatest accuracy. The occupancy
sensors learn from their mistakes and make adjustments accordingly.
Therefore, no manual sensitivity or timer adjustments are necessary –
providing maintenance free “install and forget” operation.

| occupancy sensor selection guide
step 1 technology selection

Choose the technology most appropriate for the type of activity.

Passive infrared (PIR)

PIR technology senses occupancy by detecting the difference between
heat emitted from the human body in motion and the background space.
PIR sensors require an unobstructed line-of-sight for accurate detection.
These sensors utilize a segmented lens which divides the coverage area
into zones. Movement between these zones is interpreted as occupancy.
Generally, PIR sensors are good at detecting major motion (e.g. walking) and
work best in small, enclosed spaces with high levels of occupant movement. best for use in areas with:
• an unobstructed view
considerations: • high air flow
• Ensure a clear line-of-sight between the lens and the location of the activity • ceiling fans
• Ensure that there is a discernable temperature difference between
occupant and ambient temperature

Ultrasonic (US)
Ultrasonic technology senses occupancy by bouncing ultrasonic sound
waves (32kHz – 45kHz) off objects in a space and detecting a frequency
shift between the emitted and reflected sound waves. Movement by a
person or object within the space causes a shift in the wave frequency,
which is interpreted as occupancy. Ultrasonic occupancy sensors are
good at detecting minor motion (e.g. typing, reading) and do not
require an unobstructed line-of-sight, thus making them suitable for best for use in areas with:
applications such as an office with cubicles or a restroom with stalls. • low air flow
• partitions and dividers
considerations: • a high level of minor motion
• Do not place within 6ft. of HVAC as this may cause false triggering
• Avoid placement facing doors or exits as coverage may spill
into adjacent areas

Dual technology (DT)

Dual-technology occupancy sensors use both passive infrared and
ultrasonic technologies for maximum reliability. These sensors also
minimize the risk of false triggering (lights coming on when the space
is unoccupied). Both US and PIR technologies must detect occupancy
to turn lighting on, while continued detection by only one technology
will keep lighting on.

step 3 coverage considerations

Determine the range of coverage ensuring that all appropriate

areas of the space are within the sensor’s reach.

You may need to use more than one sensor in order to get the
appropriate coverage. To ensure maximum coverage reliability,
overlap coverage of each sensor as shown below.

Considerations:
• Ensure that the activity is within coverage
• For adequate minor motion detection use half
of the rated coverage
• Provide overlapping coverage to ensure reliability
• Overlap coverage by 15% – 20%

See product information on pages 14 – 19

15% – 20% overlap coverage for specific range of coverage data.

wall switch occupancy sensors

LOS-S Series
The LOS-S series of sensors offer a direct and quick
replacement of wall switches for stand-alone line voltage
switching of small spaces. Ultrasonic sensors provide
excellent detection of minor motion such as typing at
a keyboard. Infrared detectors have good false tripping
immunity, and are better suited for major motion such
as walking.

A two-circuit version of the PIR wall switch (LOS-S2IR-HD)

is designed for dual-level lighting applications and allows
for two primary input circuits, each with independent
switching. The ‘HD’ versions of this series have a hardened
lens, which provides a barrier to accidental and vandal-
imposed damage.

Lutron offers ‘M’ models (LOS-SIR-M-WH and LOS-SIR-M-IV),

which are manual-on occupancy sensors. Users push
the button to turn the lights on and the lights turn off
automatically when space is unoccupied. These ‘M’
models meet Title 24 energy code requirements for
residential buildings in California.

LOS-SIR-HD-WH Key features:

shown actual size • Coverage from 900 sq. ft to 1000 sq. ft
• Passive infrared (PIR) and ultrasonic (US) technologies
• LOS-SUS model has self-adaptive technology which
automatically adjusts timing and sensitivity
• 120/277 VAC dual voltage operation
• Dual circuit with independent switching
