DOS AND DONTS

Do

> Use ultrasonic sensors in areas screened bypartitions or urniture

> Use PIR in enclosed spaces

> Create zones controlled by dierent sensorsto manage lighting in large areas

> Use dual technology sensors or areaswith very low activity levels

> Install sensors on vibration-ree, stablesuraces

> Position sensors above or close to the mainareas o activity in a space

> Integrate sensor use with other controlmethods (i.e. time scheduled control)

> Educate occupants about the new devicesand what to expect

Passive inrared (PIR)technoogyPassive inrared technology detectsoccupancy by reacting to inraredenergy sources, such as a human body,in motion.

Utrasonic (US)technoogyThe sensor emits ultrasonic sound wavesthat bounce o objects in the coveredspace, and then measures the amount otime it takes or the waves to return.

Dua technoogy (DT)Sensors that employ PIR + US sensingtechnologies are usually reerred to as"dual technology". Our Dual technologyensure maximum sensivity andcoverage in tough applications oroptimal reliability and energy saving.

Seect coverage patternsA coverage size and shapes is availableor each sensor technology. While a smallapplication is easily covered with onesensor, larger applications benet rom

grouping controlled lighting into zones(with each zone controlled by a sensor).Familiarity with these coverage patternswill help designers speciy the right

Step 3 - Design and speciy the project

Product eatures

Sart actory setLegrand ceiling mount sensors areshipped with actory pre-set. Thisunction assures the constructor andinvestor that the sensor will provideenergy savings as soon as it is installedwithout any commissioning.

The actory pre-sets are:

tm lx Ssby

cm

sss15 500

PIR 100% ,tT(PIR 100%, US 75%),

US (75%)w

msss

15' 300PIR 100% ,tT

(PIR 100%, US 75%)

O course these settings are adjustableusing commissioning tools.

Dayight set point =Reguation

The light level eature holds lightingOFF when natural light levels riseabove a pre-set level. This setting isadjustable and can be overridden.This unction is enabled by deault.

low profeMany applications call or lightingcontrols that dont take up a lot ospace and that leave the ceiling lookinguncluttered. Legrand sensors aredesigned to be extremely low prole

and compact.

CaibrationFor precise lux measurement, mostLegrand sensors permit to modiythe lux seen by the sensor withcommissioning tools, as the colour othe foor, the urniture etc... have an

infuence on the lux measurement.

Wak-through mode

For extra energy savings, walk-throughmode switches lights o three minutesater an area is initially occupied ino motion is detected ater the rst20 seconds. This unction is activatedby deault.

When enabled, this unction works inthe ollowing manner: when a personenters the room, the lights go ON.I the person leaves the room within20 seconds, the sensor will turn thelights OFF 3 minutes ater the initialdetection. I the person stays in theroom longer than 20 seconds, the settime delay o the sensor applies.

AertsAudible alerts warn occupants oimpending shuto. Audible alerts

preventing lights to turn o on theoccupant to comply with design orall rule.

ZigBee counicationIn renovation, it is sometimes dicultto make a vertical cabling betweenthe wiring devices and the sensor.To meet this specic requirement,

Legrand oers detectors equipped withtechnology ZigBee. This makes it easyto connect your control devices to yoursensors without any wiring!!

ZigBee: Radio communication protocol

Test odeTest mode allows to check and modiythe coverage pattern o the sensor.

Terina wiringLegrand sensors oer several typeso terminal wiring to make installationquick and easy:

- Automatic terminal or single relaysensor.

- RJ 45 connectors or a sensor in

combination with a room controller.

IPTo comply with all installation andenvironment constraints LEGRANDsensors oer a wide range o IPProtection IP 20, IP 42 & IP 55

High perorance ensHigh-perormance detection with IRlens Fresnel technology. Injectionmoulded lens, using IR 4 material

Vacancy/Occupancyode seectionMost o Legrand sensors can workusing occupancy mode (by deault) orvacancy mode.

Occupancy mode means that lights areautomatically turned on or o accordingto occupancy.

Vacancy mode means that lights aremanually turned on and automaticallyturned o. The vacancy mode oersextra energy savings.

lighting designers shoud aso consider specifc eatures, which can addunctionaity and flexibiity to the contro soution.

Zero crossingZero Crossing Circuitry ensures thatswitch sensor switching takes place atthe beginning o the voltage wave veryclose to zero volts. This reduces stresson the relay and increases sensor lie.

Wa ounting

Wall mount sensors have a mountingbase. For easy and quick mounting thebase has to be xed against the wall,thewires connected to the automatic wiringblock. Then the sensor part is ttedonto the base.

Ceiing ounting

All sensors have built-in bracketsystems that enable ceiling mounting.Most sensors are suitable or standardEU boxes (diam 65).This is important or applications wherethe ceiling is unavailable or sensorinstallation.Only one Cat.No or two ways o

mounting.

Step 4 - Instaation and coission

Sensor paceent, instaation and settings

Sensor paceentInstallers should position the sensorso it has the best view o the entirecoverage area. Care should be takento minimize the possibility o alse ONsor OFFs due to sensor location. Forinstance, an ultrasonic sensor shouldnot be positioned near an opendoorway, since a passer-by couldtrigger lighting ON.

InstaationWhen installing the sensor, thecontractor should wire it accordingto manuacturers instructions toeliminate any unctional problems orsensor damage.

SettingsMost sensors eature Smart Factory Settechnology, adjustments are typicallynot needed ater installation.

I adjustments need to be made (dueto last minute changes in urniture or

xture placement), sensitivity and timedelays should match the activity levelso the monitored spaces.

or advanced confguration:or standard confguration:

Cat.No 882 35 Cat.No 882 30

Two coissioning toos can be usedto adjust settings:

- Time level:3, 5, 10, 15, 20 mn

- Lux level:20, 100, 300, 500, 1000 lux

- Occupancy, occupancy walkthrough,vacancy, modes

- PIR & US detection sensibility: low,medium, high, very high

- test mode

This comissioning tool enables a veryprecise commissioning o your sensors.

- Time: rom 0 seconds to 60 mn

- Lux: rom 1 lux to 1275 lux

- Detection mode: occupancy,occupancy walkthrough, vacancy modes

- PIR & US detection sensibility: low,medium, high, very high

- It also provides access to advancedunctions such as calibration,alarms, choice o mode o detection(initial detection, maintain detection,retrigger), daylight unction

- It also allows to download sensorparameters, to save these parametersin olders, to duplicate them

Standards on energy savings

European Standard EN15193 provides a guideline or the energyperormance o lighting systems. Legrand has chosen this standard as abasis to demonstrate the energy perormance o its lighting solutions.This standard is widely recognized and provides a calculation methodologyon energy savings according to the type o solution installed, the type obuilding and the type o room.

Putting a stop to energy wasteLegrand is commited to providing customers withcomprehensive, transparent inormation on actualsavings or its lighting management solutions: saving onenergy + Green House Gas (GHG) emissions avoided.

Look or this inormation in our best practiceliteratures.

Green Buiding prograes

Green Building is an approach to building that considers the overallenvironmental impact o a building as well as the health and well-beingo its occupants.Green Building programmes are voluntary, consensus-based programmesthat provide guidelines. These programmes generally have an associatedrating tool or assessing the environmental perormance o the buildingand certiying its compliance with the standard.Green Building certication is awarded to dierentiate sustainable buildingprojects and give them credibility. Major Green Building programmesinclude LEED, BREEAM, HQE and GREEN STAR.
