Basic principles
Infrared radiation, alsoknown as thermalradiation, is associatedwith electromagneticwaves. Each object emitsthermal radiation accordingto its specific temperature.
for detection purposes. TheBusch-Watchdog® Presencehas 4 sensors, an optimisedlens and an additional high-quality system of mirrors sothat even the slightestmovement from peoplewho are seated can bereliably detected.
As a room heats up, itsthermal radiation changesat a very slow rate incomparison. It is therebyguaranteed that anymovement by people (ther-mal movement) can bedetected.
IR sensor technology
Traces of infrared can bedetected with infrared sen-sors and converted intoelectrical signals. As these
sensors only receive and donot emit any infraredradiation themselves, theyare also called “passive” IRsensors.
Optical system
The monitored area is divid-ed into numerous fields orsegments with the aid oflenses, mirrors andsensors. If someone movesfrom one segment to anoth-er, this movement is detect-ed. The higher the numberof segments, the smallerthe movement needs to be
Passive IR sensors
Passive IR sensors aredesigned so that they onlyreact to changes in thermalradiation e.g. due tomovement. If the thermalradiation is at a constantlevel, no signals areproduced.

Prerequisites for detection of people
The movement of people,including the slightestmovements made whilesitting at a PC workstation,is dependent on themounting height and the

reduced. Depending on theapplication, a greaterresolution is not requiredand a higher mountingheight is possible (e.g. instorerooms, corridors,hallways).
Exterior detection area
(with people walking)
When detecting peoplewho are walking around, alarger detection area is
Interior detection area
(with people sitting
down)
People who are seatedmust be positionedcompletely within thedetection area. The smallerthe distance between theperson and the Busch-Watchdog® Presence, thesmaller the movementneeds to be for detection
purposes. The referencelevel for the detection ofseated activities is approx.1 m. At this height, thedetection area is 6 m indiameter (mounting heightof the Busch-Watchdog®
Presence = 2.5 m). At agreater mounting height,the detection area will belarger but the monitoringdensity will be reduced.
Mounting heights
The detection propertieschange dependent on themounting height. As themounting height increases,the sensitivity andmonitoring density are

Interference sources
Switching operations arenormally triggered by peoplemoving around. Externalheat sources can also causeunwanted switching
operations which shouldbe taken into account atthe planning stage.
• strips of luminaires whichhave been inserted deeper than the Busch-Watchdog® Presence
• large plants• partition walls• panes of glass
• additional fans• switching on/off of lamps
which are in the direct vicinity (< 1.5 m) of the Busch-Watchdog®
Presence, especially incandescent and halogen lamps
• moving machinery, flapping posters
• radiators (distance> 0.5 m)
• surfaces warmed bythe sun
• EDP systems (computers, printers, monitors)
• ventilation systems as the warm air is flowing directly into the detectionarea of the Busch-Watchdog® Presence

Setting options
1. Measuring daylight
A main advantage of theBusch-Watchdog®
Presence lies in the evalua-tion and disconnection ofthe lighting without
dependence on movementin order to achieve thegreatest potential forsaving energy. In contrastto conventional motiondetectors which are only
activated below a dusk val-ue, the Busch-Watchdog®
Presence must constantlymeasure and assess thebrightness and then switchthe light on or off
accordingly.
7
value measured at theworkstation is thus storedas the new higherbrightness limit.
2 Brightness limit is set
too high
This means that the lightingis still switched on althoughthe daylight coming into theroom would be sufficient.The lighting is switched offvia remote control and thebrightness value is stored.A lower current brightnesslimit is therefore stored andthe lighting is switched onearlier.
* The function is not availablefor the Busch-Watchdog®
Presence EIB as modificationscan be carried out in this casevia the laptop
Adaptation of the
brightness limit via IR
remote control*
The Busch-Watchdog®
Presence enables a simpleadaptation of the set bright-ness value using IR remotecontrol without disruptingthe operating sequence andinstallation work.

Extension input operation
If required, the Busch-Watchdog® Presenceoffers the possibility at anytime for manualintervention into automatic
processes. The lighting canfor example be switched offin this way for presen-tations. In exceptionalcases, it is possible to
switch on the lighting direct-ly at any time regardless ofthe selected setting. Thereturn to the automaticmode is carried out

Active extension unit*
In large rooms in which oneBusch-Watchdog® Presenceis not sufficient, thedetection area can beextended using additional,economical extension units.The switching function iscarried out by the masterunit. It is advisable to installthis master in the darkestplace in the room and todefine the brightnessvalues measured as
• after continuous movement and underflow of the brightness limit over 4 hours.
2. Lighting is switched off
The lighting can beswitched off (if already on)by pressing the rocker on aconnected plateswitch.When the lighting isswitched on again for aminimum of 2 hours, theBusch-Presence reverts toautomatic operation, wherethe light setting isdependent on movementand brightness.
Push button operation*
In this case, conventionalplateswitches areconnected to the extensioninputs of the respectiveflush-mounted inserts.

3 Adapting the brightness
limit for constant lighting
control
In connection with a flush-mounted dimmer insert,the lighting can beswitched on or off ordimmed with remotecontrol. The lighting isswitched on and off after ashort push button actionbut the brightness limit isnot changed. The lightingcan be dimmed with a longpush button action. If theset brightness is to bestored as the limit value,the “Memo” button mustbe pressed twice. If thebrightness is changed by adimming process duringnormal operation (withoutpressing the “Memo”button twice), the automat-ic function is interrupted for2 hours. The Busch-Watchdog® Presence thenreverts to the originalstored value.

Application example: Single office
Task
The lighting in an officeshould be controlledefficiently via a Busch-Watchdog® Presence. Itshould also be possible to
switch the lighting on andoff manually with a pushbutton. The heatingshould then be integratedas the next phase.
Installation and settings
The installation site of theBusch-Watchdog® Presenceshould be selected abovethe workstation to providethe best level of detection.The installation can beflush-mounted or surface-mounted if an adapter isused. The brightnesssetting is carried out via the“Lux” potentiometer. A set-ting between 50 and 100lux measured at the ceiling
can correspond to abrightness level of 300-400lux at the workstation,depending on the reflectiveproperties of the room. TheOFF delay is defined inthese applications atapprox. 10 minutes. Anadapter is provided for thesimplemounting/dismantling ofthe sensor during theadjustment and installationstage.
Additional integration of
heating control
The greatest energy-savingpotential lies in heating con-trol. It is a good idea toreduce the temperature inthe room via night reductionif no movement is detected.It is however generally notadvisable to disconnect theheating completely. Eachdegree of temperaturereduction leads to a savingin heating energy of approx.6%. In the case of roomtemperature controllerswith night reduction, thetemperature is lowered byapprox. 5°C. Depending onthe thermostat used, the230 V input for the night
reduction must be interrupt-ed on detection ofmovement so that thethermostat regulates thetemperature to the normallevel. This circuit can beconverted with the help ofan external, NC relaycontact. A motion-dependent ON delay is alsolinked to the OFF delay. Ifthe OFF delay is set at > 10minutes, the HVAC output isonly activated if continuousmovement is detected. It isnot advisable for example toswitch the heating on (orincrease to comfort temper-ature) if someone brieflyenters the room.

Application example: Large office (separate lighting circuits)
Task
The lighting in a large officeshould be controlled viapresence detectors. Thereare 4 workstations whoselighting should be controlled
separately via the Busch-Watchdog® Presence. Thecontrol of the heatingsystem should be motion-dependent and imple-mented at the next stage.
Installation and settings
The installation site of theBusch-Watchdog®
Presence should be select-ed directly above the work-stations to provide the bestlevel of detection. Thedetection area of each indi-vidual device must beadapted to the environmentby covering the long-distance plane or part ofthe medium-range plane(special film is suppliedwith the device) so thatonly the corresponding sec-tion is detected. In thisapplication, it is necessaryto ensure that the individuallighting circuits influenceeach other as little as possi-ble. The greater theinfluence exerted, the moredifficult the setting of the
brightness limit of each indi-vidual Busch-Watchdog®
Presence becomes.Increasing the brightnessby switching on an adjacentgroup of luminaires is thesame as an increase in theexternal brightness for theBusch-Watchdog® Presenceand can lead to thedisconnection of its groupof luminaires. If IR remotecontrol is to be used itshould be ensured that themaximum range of theremote control is 7 m. Torule out faulty operation/programming of otherdetectors it must be aimedas vertically as possible atthe Busch-Watchdog®
Presence which is to beoperated.
Additional integration of
heating control
The process is dependenton the respective heatingsystem. There are heatingsystems which permit eachheater to be controlled sep-arately. These heaters canbe regulated as describedin the single officeapplication. If it is not possi-
ble to control the heatingseparately for each area,the HVAC outputs of therespective universal seriesinserts 6402 U must beconnected in parallel. It istherefore ensured that theroom is heated even if onlyone workstation isoccupied.

Application 1
The fan should start with anON delay of 30 sec. andcontinue for a maximum of10 min. The setting on the“Time/HVAC”potentiometer must be setbetween 1 and 10 min.
Application 2
The fan starts with an ONdelay but only if amovement is detected overa longer period (e.g. 5 min.). This should preventthe fan from starting whensomeone has only enteredthe toilets for a short time.If a movement is detectedover a longer period, the fanshould continue for sometime. The “Time/HVAC”potentiometer must be setat > 10 min. The ON delayis based on the frequencyof movement in the firstfew minutes. If only onemovement is detected, theHVAC output is notswitched.

Application example: Constant lighting control
Task
Constant lighting controlensures increased comfortin offices and conferencerooms. The lighting isgenerally a mixture of
daylight and artificial light.In this type of lighting con-trol, the brightness is main-tained at a constant levelby dimming the artificiallight. If daylight alone is
sufficient, the artificial lightis switched off.
Lighting control
The lighting must bedimmable. The flush-mounted dimmer insert isselected dependent on theload (fluorescent lamps,incandescent lamps etc.).Manual intervention viaplateswitch or IR remotecontrol is also possiblewith constant lightingcontrol.
The lighting can beswitched on and off withthe plateswitch. It ispossible to distinguishbetween short and longoperations with IR remotecontrol. A short push buttonaction is identical to thefunction of the plateswitch.The lighting is dimmed aftera long push button action.

Adaptation of the
brightness limit with
remote control
Using infrared remotecontrol, it is possible toadapt the brightness limitwhich is kept at a constantlevel.
The lighting is dimmed dark-er or brighter after a longpush button action. If thedimming process hasfinished, the “Memo”button is pressed twice tostore the values.

Application example: Interface to Busch-Powernet® EIB
Task
To extend a Busch-Powernet® EIB installationwith a presence detector,the outputs of the flush-mounted insert are
connected to the Busch-Powernet® EIB installationvia a binary input.
Installation and settings
The choice of location andthe detection area of theinstallation area is identicalto that of the single officeapplication. The outputs ofthe Busch-Watchdog®
Presence must be connect-ed to a binary input. Thiscan for example be mount-ed directly in suspendedceilings or installed in the
distribution board. The set-tings are identical to thoseof the single office applica-tion.The connection of theplate-switch and themaster/slave concept aswell as the use of IRremote control is possibleas described in theprevious applications.
Addition of heating
control
The universal series inserthas 2 outputs. Both outputsmust be linked to theBusch-Powernet® EIB via abinary input. Further heatingcontrol is then achieved byusing EIB. It is also a goodidea to lower the
temperature in the room viathe adjustable nightreduction of the appropriatethermostats if no movementis detected. All furthersettings regarding the OFF-delay in combination withthe intelligent ON-delay areidentical to those of thesingle office application.

Busch-Watchdog® Presence EIBApplication example: Interface to ABB i-bus® EIB
Task
Controlling the lighting andtemperature in a room withstandby, comfort and night-time modes. The processneeds to be fully automatic
and involve both energysavings and costreductions. When linked tothe ABB i-bus® EIB, it ispossible for the respectivefunctions to communicate
and react with each other.The detection of variousbrightness values within aroom and the direct reactionto these values is alsorequired.
Example 1:
Presence/HVAC/Signal
Switching from standby
to comfort mode for light
and temperature
As soon as someone entersthe room, the presencedetector switches the lighton and the room thermostatswitches from standby tocomfort mode. If nobody isin the room, the heating is
set to standby mode oncethe respective overshootperiod has expired and thelight is switched off. In theevening, the roomthermostat is automaticallyset to night operation via atimer. The signallingfunction of the presencedetector is enabled at thesame time so that roommonitoring can take place.

Example 2: Presence
1/Presence 2/Signal
Detection and adjustment
of various brightness
values
The presence detector canprocess 2 brightness limitsand thus adjust to variablelighting conditions in theroom. This makes itpossible, for example to
switch-off the row ofluminaires at the window(setting = 200 lux) earlierthan the row inside theroom (setting = 300 lux).Once the signalling functionhas been successfullyactivated via the bus, it canbe used to monitor theroom.

Example 3: Presence
1/Presence 2/HVAC
Individual reaction and
connection of the
heating or air
conditioning system
The lighting controlfunction corresponds toprevious application exam-
ples but also includes theHVAC mode. This meansthat if someone is in theroom, the heating or airconditioning system switch-es to comfort mode. Ifnobody is present, it revertsto the cost-effectivestandby function.
Example 4: Presence
detector combined with
constant light controller
Reaction to ambient
brightness by constant
lighting control
When dimmable electronicballasts are used (0-10 V),constant lighting controlcan be produced in additionto the presence detectorfunction. This combinationoffers the highest potentialfor saving energy in theroom. To do so, a constant
light controller such asOsram HF DIM MICO isconnected in parallel to the0-10 V control terminal ofthe electronic ballasts.
This controller maintains thelighting at a constant levele.g. at 500 lux. If theambiant light levelincreases, the artificial light-ing is dimmed down, sothat additional energy issaved even when the roomis occupied.
