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

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 'sensor-link' 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.


The layout of the space should be considered

carefully when selecting an occupancy sensor.

Areas to Consider:

Private Office

Private & Multi-Stall Restrooms

Utility Closet

Copier / Mail Room

Health Care Labs & Exam Rooms

Storage / File Rooms

Locker Room

Janitor’s Closet

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.

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

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%

(Both poles should be operated from the same circuit)

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
