ENERGY SAVINGS
Occupancy sensors deliver maximum energy savings,
exceeding the savings provided by other control solutions
(i.e. scheduling), by ensuring that lighting is only on when
people are present. NexLight, the world’s top producer of
design built and easy to use lighting control systems,
continues its mission by providing new sensors that save
energy and assist in achieving additional design goals.
EFFICIENCY INCENTIVES
The use of occupancy sensors can assist building owners in
earning Corporate Tax Incentives including credits, deduc-
tions, exemptions and rebates based on the equipment
installed. To qualify, a building must meet or exceed the
energy performance required. Visit www.dsireusa.org for
more information and updates for your local area.
SUSTAINABLE BUILDINGS
By designing beyond the requirements of codes, design
teams can provide even greater energy savings and work
toward sustainable building practices. LEED certification
points are awarded with correct application and use of
sensors. The result is another way of providing the commu-
nity with green and energy efficient buildings.
ENERGY CODE COMPLIANCE
PerfectSense products provide convenient code compliant
Automatic-ON or Manual-ON control and are full of innova-
tive features. Our sensors use Passive Infrared (PIR),
Ultrasonic, and a combination of the two, commonly
referred to as Dual-Technology. Both Automatic-ON and
Manual-ON sensors meet the Automatic-OFF requirement
of all major energy codes, including ASHRAE 90.1 (2007 and
earlier), IECC and California’s Title 24.
ASHRAE 90.1-2010 is now including the requirement for
many spaces to be Manual-ON. A space may use
Automatic-ON control, however the Automatic-ON func-
tion cannot turn on more than 50% of the space lighting.
Whichever method your space requires, PerfectSense
offers a complete selection of compliant solutions.
AUTOMATIC-ON + BI-LEVEL CONTROL
Bi-level switching has the potential to save energy by
enabling occupants to use just as much lighting as they
want, and is a requirement by EPAct, California’s Title 24
and ASHRAE 90.1 2010. Bi-level Auto-on control is when
one zone is turned on automatically (by the sensor) and the
other zone must be turned on manually (local switch).
This method of control has been shown to use 52% less
energy* than Automatic-on only. Additionally, many occu-
pants are comfortable working in lower lighting levels. The
result are dramatic energy savings and enhancing occu-
pant comfort. (*BasedonCaliforniaLightingTechnologyCenterresearch2009.)

PerfectSense gives engineers and facility managers more control
options than ever before, offering sensors that are the best fit for
any application. Sensors featuring Passive Infrared, Ultrasonic or
Dual Technology are ideally suited for different applications. Let’s
take a closer look at each type.
PASSIVE INFRARED
Passive Infrared (PIR) technology detects occupancy in the space
by sensing the difference between temperatures of a human body
in motion and the background space. Requiring a line of sight for
detection, PIR sensors feature accurate area coverage cut-offs.
ULTRASONIC
Ultrasonic (US) technology operates by transmitting an ultrasonic
sound wave into the space and measuring the speed at which they
return back to the sensor. Occupant movements change the
frequency of the waves. This means ultrasonic sensors can detect
movement around partitions or indirect line of sight.
DUAL TECHNOLOGY
Dual Technology operates by combining PIR and ultrasonic detec-
tion into a single device. This technology increases the accuracy of
detection while decreasing the potential of false ON or false OFF
triggers.

APPLICATION EXAMPLES
Large conference rooms require detection that will account for
occupants that may be still for long periods of time. Dual technol-
ogy sensors will be able to detect minor motion to keep lights on
as long as the space is occupied.
Copy rooms, IT rooms, and janitor’s closets are ideal for occu-
pancy based controls. With a wall or switch mounted PIR sensor,
lights can be shut off just minutes after the occupant leaves
saving hours of wasted lighting energy each day.
Classrooms large and small require the ability to detect minor
motion. Ceiling mounted dual technology sensor models are
preferred to get complete room detection. In larger rooms a
second sensor and power pack could be added for multizone
control.
In private offices, use a PIR or dual tech sensor depending on
room layout and field of view. Take advantage of the integrated
light level feature to keep lights off when sufficient daylight is
present.
Lighting in restrooms is best controlled with ultrasonic sensors to
eliminate hundreds or even thousands of hours of unneeded
on-time during a year. A ceiling-mounted ultrasonic senses
motion around restroom stalls for greater coverage area.
For the open or partitioned office spaces, either the dual tech or
ultrasonic type may be appropriate. Wall mounted or on the
ceiling, expand coverage of large spaces by linking multiple
sensors together to control lighting in a coordinated way. Use
these sensors to cover the area in zones with 10-20% overlap as
illustrated above.

Understanding daily space usage patterns are essential to
properly apply occupancy sensing in a commercial building
space. If you are able to answer “YES” to some of the following
questions, adding occupancy sensors are a viable control
option.
+ Are there periods of time when the space is unoccupied?
+ Is energy wasted due to lights being left on when no one is
in the space?
+ Are lights left on after business hours?
+ Is the space used only intermittently?
+ Could some or all area lights be turned off during the day?

1. EVALUATE SPACE NEEDS
The following space characteristics are of particular
importance because of the influence they have when
making a sensor selection:
+ Room / Space dimensions and shape
+ Location of main occupant activity
+ Location of walls, doors, windows and drapes
+ Location of desks / workspaces and orientation with
regard to walls and partitions
+ Ceiling heights, partition heights and locations
+ Location of file cabinets, large furniture, large
equipment or shelves
+ Large objects that could block or alter a sensor
coverage area
+ Available daylight for added light level sensing
+ Make note of high levels of air flow or vibrations
noting the location of HVAC ducts and fans

3. LAYOUT & SPECIFICATION
COVERAGE PATTERNS
Once the technology is chosen, the next step is to select
the correct coverage size and shape. A typical design
guideline will call for a minimum of 90% coverage area of
the square footage in a room. Each product cut sheet
includes specific coverage area specifications.
It’s important to know the typical use of space. Will occu-
pants be engaged in major motions (walking, using a
forklift) or minor motion (reading, typing). Coverage
changes depending on motion type.
NEMA TESTING
PerfectSense understands the importance in producing
the highest quality products. When it comes to occupancy
sensors, that means producing sensors with consistent
detection while reducing False Triggers. All PerfectSense
products are designed to meet and exceed the quality and
consistency standards set forth in the National Electrical
Manufacturers Association guide publication. The NEMA
guide establishes two testing parameters as major and
minor motion detection. It defines minor motion as the
movement of a person sitting at a desk reaching for a
telephone, turning the pages of a book, opening a file
folder, or picking up a coffee cup. Major motion is defined
as the movement of a person walking in or through a
space.
CHOOSE POWER PACKS
Power packs are a necessary component providing
three core purposes to most occupancy sensor projects.
Power packs provide power to low voltage sensors and
other control devices, respond to signals from those
devices and switch their internal relays to control the
connected loads.
Power packs can also provide advanced features such as
switch inputs, inputs for scheduling, and dimming
control. Before selecting a power pack, consider the
following factors.
Voltage: Pay attention to the input ratings of each
power pack model.
Low voltage output needs: Typically listed in (mA) be
sure the power pack provides enough current to power
all of the connected devices for that zone.
Relay ratings: Power Packs have specific ratings for
different load types (i.e., incandescent, fluorescent,
motor). Make sure the relay is rated for the type of load
to be controlled and the load being switched does not
exceed the load rating of the power pack.
To protect against the potentially damaging effects of
high inrush current common in newer electronic
ballasts, select power packs with zero crossing circuitry
technology.

4. INSTALL & CONFIGURE
INSTALL THE SENSOR
During installation contractors should position the sensor
so it has the best view of the entire coverage area, while
minimizing the possibility of false ON and OFF triggers.
Wire sensors according to instructions. This will eliminate
any functional problems or sensor damage. If necessary,
adjust sensor settings such as the sensitivity, time delay or
daylight sensing to match the activity levels of the space
being controlled.
Be sure to increase the off time delay setting for spaces
where minor motion and limited activity will be taking
place to further reduce the risk of false offs. For increased
energy efficiency shorten off time delay settings especially
for areas of high traffic. For restrooms, stairwells or areas
with limited or no natural lighting use caution and set
longer off time delays to ensure occupant safety and secu-
rity.
MOUNTING SENSORS
PerfectSense products fall into three categories of
mounting: Ceiling, Wall, and Wall Switch types. Only
wall mount types may be mounted on both the wall
or the ceiling. This is important for applications where
one of the surfaces may be unsuitable for sensor
installation.
MOUNTING POWERPACKS
Power packs are often mounted to the outside of a
junction box, placing them in the plenum space, so
make sure the power pack is plenum rated. Smaller
power packs can be installed inside a standard junc-
tion box.
WIRING POWERPACKS
Intelligent power packs provide inputs so that multiple
control devices can be connected. This enables customiza-
tion of control scenarios for different applications and end
user preferences. Use intelligent power packs when
multi-device, manual switching, and dimming applica-
tions are desired.
PHOTOCELL CONTROLS
Most occupancy sensors include an integrated daylight
sensor to be used in building spaces that receive daylight.
This function is designed to ensure the occupancy sensors
will keep lights off in occupied spaces, when the natural
daylight coming into the space exceeds the set threshold.
If a space has inadequate natural daylight the occupancy
sensor will turn lighting on.
PROGRAMMING AND TESTING
Make post-installation adjustment as needed. This is not
uncommon and is often due to last minute changes in
placement of furniture or fixtures. A walk test of the detec-
tion area is a common method of ensuring the sensor is
located and configured properly for the space.
TIP: Double check
specified sensor
location prior
to installation
TIP: Wire according
to instructions for
proper power pack
and sensor function

INTEGRATING SENSORS WITH CONTROLS
Occupancy sensors that operate independently in a space,
are referred to as “stand alone” sensors providing no infor-
mation of occupancy status to other building systems. To
increase control and energy savings, PerfectSense low
voltage occupancy sensors include isolated Form C relays
to seamlessly integrate with Building Management
Systems (BMS), HVAC (VAV controllers) or NexLight 2-Wire
Lighting Controls Systems. These relays providing real
time occupancy status “intelligence” to other systems,
adding signifcantly to a building wide control strategy and
potential savings. PerfectSense has the industries only
sensor with multiple relay outputs for greater connectivity
to building controls.
MULTILAYERED CONTROL STRATEGY
For the next level of efficiency, consider combining occu-
pancy sensors with other controls such as lighting control
panels or daylight harvesting controls. A multilayered
control strategy can assist in meeting energy codes and
green sustainability guidelines as well as provide maxi-
mized energy savings.
The images below illustrate an example of how a low
voltage sensor could be networked to a building BMS or
2-Wire lighting control system.

Overview:
The PS-DTC24 increases area lighting energy efficiency quickly
and easily by combining industry leading Passive Infrared (PIR)
technology with Ultrasonic for superior detection. Factory
preset to deliver significant savings out of the box, this sensor
has additional options to further increase energy savings if
desired. The PerfectSense PS-DTC24 is a low-voltage sensor
that works with PerfectSense class 2 power supply (PSPP1277),
to automatically control lighting. The sensor turns the lights
on and keeps them on when occupancy is detected and will
turn the lights off after the delayed-off time has expired.
Operation:
The sensor first sees motion using the PIR detection and then
activates Ultrasonic to confirm and indicate continued occu-
pancy. The standard factory programming is set to meet the
standards of most common area applications with a 10 minute
off delay time.
Additional Operational Features:
Walk-Through Mode: useful when a room is momentarily
occupied, like a storage area. When a person enters the room,
the lights turn on. If the person leaves the room before the 2.5
minute walk-through timer expires the sensor will turn the
lights off. If the person stays in the room longer than 2.5
minutes the sensor will proceed to standard operation.
Single-Tech Mode: Only one technology is active in this mode.
Dip switch selectable, a user may determine that the space
may only require one technology to properly detect the area.
One sensor model can now act as a PIR only, Ultrasonic only or
Dual-tech sensor.
Daylight Sensor: The integrated daylight sensor allows for
ambient light override functionality. If this setting is enabled,
the controlled lighting load will only turn on if the ambient
light present is less than the preset level.
Adaptive Learning: Patented adaptive learning technology will
automatically increase or decrease the off delay time in
response to the occupancy and environmental conditions of
the area over a period of time. For example, if there is
frequent motion detection, the sensor will automatically
shorten the off delay time to better meet the conditions of the
room. This technology also detects false off conditions. If this
happens, the off delay time duration will immediately be
lengthened to avoid future false off conditions.

Overview
The Wall-Mounted Dual Technology Occupancy Sensor employs both passive
infrared (PIR) and ultrasonic technology to accurately detect occupancy and
automatically turn on lighting.
To reduce the occurrence of false on events, this sensor employs PIR technology to detect
major motion. Once lighting has been turned on, it employs highly sensitive PIR and ultrasonic
technology to detect minor motion and keep lighting on while areas remain occupied. When the
room or area is no longer occupied, the sensor turns off lighting after a pre-set time delay.
The low profile sensor is wall-mounted for greatest sensitivity to motion in large areas with
obstructions. With a 110º degree field of view and up to 2500 square feet of coverage area when
mounted at 8 ft. off the ground, the Wall-mounted Dual Technology Occupancy Sensor is ideal
for conference rooms, classrooms, bathrooms, and large office areas.
These wall-mount sensors also incorporate an integral light level sensor to prevent lighting from

Common Stand Alone Control Strategies
PerfectSense
®
45
Auto On / Auto Off is the most basic occupancy control strategy.
Requiring only a standard power pack and low voltage sensor,
the space is controlled based on occupnacy with no manual
override control. Line voltage wall switch sensors may also be
configured to work in this manner. Consult local codes for using
this scenario in approved locations.
50% Manual On / Auto Off requires one lighting load to be
switched on automatically when occupancy is detected by an
occupancy sensor, while a second lighting load can be turned
on manually by the occupant if desired. Both loads can then
be turned off manually or via the occupancy sensor timing
out. Commonly required by building codes (such as California
Title 24), this is an easy and convenient method of delivering
extra energy savings without inconveniencing the occupant.
Manual On / Auto Off is the commonly used method for areas
using a single lighting load. Occupants manually turn lights
onBe sure to use a PS-PP7000X power pack designed to work
with low voltage switches.
Going above and beyond Manual On / Auto Off can be done
in a number of ways. The addition of photocells for daylight
harvesting and or 0-10v dimming are two of the most
popular choices for enahnced levels of control and energy
savings in locations with large windows, conference rooms, or
open office areas.
