Introduction to Sensors
An occupancy sensor is a control device that detects occupancy and turns lighting (or other
equipment) on or off automatically. Occupancy sensors continue to rank among the most popular
component for lighting control solutions on the market today. Turning lights on only when
needed, and off when not needed, just makes sense.

Introduction to Sensors
There are multiple types of lighting occupancy sensor technologies:
1) Passive Infrared (PIR): Contains a detection element in the which senses infrared energy. The technology
segments the lens between the detector and the coverage area and breaks the “field of view” into narrow
segments. When a heat producing body enters a segment, or passes from one segment and into another,
occupancy is detected. The lens is carefully designed and matched with the detector to optimize
recognition of human presence and motion within the target coverage area.
2) Ultrasonic: Detects occupancy by emitting a high-frequency signal that is interpreted as motion when
frequency changes. These sensors don’t need a direct line of sight since they can “sense” motion around a
corner.
3) ADI-Voice: Contains an element that detects audio and applies signal processing technology to analyze
sounds and recognize human voices. Used in applications where movements may be small but voice
sounds may be sufficient to prevent false tripping. This technology is combined with a PIR sensor where
PIR detection is required to initially close the contacts.
4) Dual Tech: Combines PIR and a second technology to reduce inadvertent turn-on and turn-off events.

The CENTO™ Family
Wall-Switch Sensors
Ceiling Sensors
Power Packs
Universal Lighting Technologies, Inc. recently expanded its product portfolio by introducing the
CENTO™ line of occupancy sensors and vacancy sensors. The name CENTO™ represents the joining
together of control with multiple energy efficient lighting technologies (CENTO™ Connects Energy
Nodes To maximize energy savings and performance).
The initial CENTO™ line includes: PIR wall-switch sensors, ceiling sensors and power packs. Functional
options are diverse, from basic to feature-rich. Voltage options include line-voltage (120/277VAC &
347VAC) and low-voltage (24VAC pulse). Most wall-switch models come in multiple colors, and
ceiling models are available with three different coverage patterns.

CENTO™ Benefits
 Easy to Install. Simple configuration using dials
and DIP switches. Products are small in size.
 Energy Efficient. Perfect for an energy efficient
lighting solution. Reduces lighting energy costs
by turning lights on when needed and off when
not needed.
 Wide Application. (see page 14 & 15). Ideal for
spaces with irregular occupancy patterns and
changing amounts of natural daylight. Family
includes 347 volt .
 Cost-Effective. Sensors pay for themselves
quickly, even without rebates. But utility
rebates may be available to support sensor
purchases.
 Control. Some models have photo sensors
which inhibit turn-on when adequate natural
light is available. Some have photo sensors
with a 0-10V dimming function for daylight
harvesting. Some have an auxiliary relay for
coordinating with local HVAC equipment, fans,
etc. And low-voltage sensors have a 'sensorlink' function, which coordinates multiple
sensors to extend the coverage area.
 Technology. Passive infrared sensing optimizes
recognition of human presence and motion in
the coverage area. Photo sensing exploits
natural daylight, providing additional energy
savings when enough ambient light is available.
 Dependable. With proper placement, the range
of PIR sensors is precise and dependable. Ceiling
mount sensors are available with multiple
coverage patterns. And, wall-switch sensors
have a hardened lens to resist damage from
vandalism.
 Adjustable. Sensitivity settings help reduce false
triggers. Easy to switch between possible
automatic, manual, and override functions
(occupancy (auto-on/auto-off) & vacancy
(manual-on/auto-off) sensors). Ceiling sensors
feature adjustable lenses for standard, extended
& high-bay sensing ranges.
 Aesthetic Appeal. All sensors are recessed and
have a very low profile. Color variations are
available for wall-switch models, and Universal
can provide recommendations for matching wall
plates.

Applications
Universal’s PIR sensor products will be used in general commercial and industrial applications. Look
for spaces where it makes sense to assure a lights-off condition when unoccupied, especially areas
that are likely to be left on overnight or areas that are not continuously in use.
Areas to Consider:
 Private Office
 Private & Multi-Stall Restrooms
 Utility Closet
Closets,
Halls
 Copier / Mail Room
 Health Care Labs & Exam Rooms
 Storage / File Rooms

Switch Mount Operations
CENTO™ line voltage sensors draw control power directly from the lighting circuit they are
intended to control. When in operation the sensor will detect initial motion using Passive
Infrared (PIR); once motion is detected, the internal contact will close. Motion through PIR
is used to maintain the occupied condition as long as occupants remain within coverage
range and line of sight of sensor. Low voltage sensors obtain 24VAC control power from a
CENTO power pack. Sensing and control functions are similar to line voltage sensors, but
without an internal contact. Instead, a directional control pulse is returned to the power
pack to open or close its internal relay.
“P” Models use the photo sensor to prevent contact closure when natural daylight is sufficient.

Line Voltage Switch Sensor Wiring
(Both poles should be operated from the same circuit)
Note: Restroom Mode (2-pole models / DIP Switch 8)
• DIP #8 = DOWN (Synchronized)
• Pole 1 & Pole 2 are controlled together
• DIP #8 = UP (Offset)
• Pole 1 & Pole 2 both turn ON when occupancy is detected
•Pole 2 time delay exceeds pole 1 by an additional 50%
Application Example:
Light on Pole 1, Fan on Pole 2, time delay 10min
- Light stays on 10 min after last occ. detection
- Fan stays on 15 min after last occ. detection

Sensor Location Guidelines
To optimize the performance of CENTO Sensors, please review the coverage pattern, range, and model
to match with the application. Room dynamics will change when people and furniture are occupying the
space. In some rooms, after move in, some sensors may require adjustments.
• Ensure that the sensor is at least 30 inches away from air handlers/registers and not pointed directly at
windows
Sensor Location Guidelines for models with photo sensors
• Place outside the direct cone of light from fixtures and between 3 to 12 feet from a window
• As close as possible to the fixture being controlled
• Above the least illuminated space in the work area
• Away from lighting that is not being controlled by the sensor
