SensaLinkIndoor Lighting Controls for interactive lightingin applications, requiring higher levels of comfort

IntroductionThorn’s Indoor Lighting Controls offer consists of three portfolios1 2 31 SensaLite features Thornluminaires with built-insensors, and remote sensors,offering stand-alone presencedetection, daylight linkingand infra-red control.SensaLite is the first step tocomfort and energy saving,and is used for small officeapplications, simpleclassrooms, corridors etc.2 ControLiteDIM is usedfor mid-sized projects (1room): The modular systemcreates scene setting,enabling daylight linkingand integrating presencedetection. It is easy tocommission by the contractor:When wiring the system, theluminaires are allocated tothe switches, scene platesand presence detectors.3 SensaLink features Thornluminaires with built-insensors and remote sensorsoffering presence detection,daylight linking and infra-redcontrol, scene setting andthe possibility to link sensors.It provides an interactinglighting management systemfor projects requiring greaterlevels of comfort.2

SensaLinkHow does SensaLinksupport the Thorn PECstrategy?Performance:SensaLink sets the right lightlevel, at the right place and atthe right time.Efficiency:SensaLink is a perfect toolto provide an efficient light.It enables you to dim theluminaires, link the luminairesto presence and link them to theincoming daylight to achieveenergy saving. Therefore lightis only provided when youneed it and in the quantity thatyou require. SensaLink alsocontinually adjusts its light outputand energy input. This maintainsilluminance over the entireperiod, saving the energy thatconventional systems waste whilefulfilling the objectives of manyinternational and local lightingstandards.Comfort:Manual dimming and presencedetection are features ofSensaLink that provide acomfortable lighting solution tothe user. SensaLink is very easy toinstall and set up. By maintainingthe illuminance level over theentire period, you will alwayshave the same light level that yourequire. Therefore the lightingremains comfortable all of thetime, without the need for regularand inconvenient re-adjustments.Additionally you can link severalzones or rooms within anapplication that interact withone another.Where is SensaLink used?The typical applications for SensaLink are:comfort of scene setting, screen and blackout blind control, e.g.lecture theatres or conference rooms that divide into smaller andindividually controlled areas.daylight and presence linked zones within each floor, e.g. openspace offices, with the possibility to link the luminaires withinthese zones and adjacent areas.FeaturesApplicationsOfficesConferenceroomsLecturetheatresClass roomsDimming and Switching Presence-link Daylight-link Luminaires interactingwith adjacent areas Distributed intelligence Scene setting Partition managementMotorised Screen control Motorised Blackout blind control 3

Overview of functions and their benefitsResponse topresence/absenceSensaLink sensor heads providepresence linking that will detectyou entering and leaving theto a pre-programmed level, and5 to 60mins. Additionally, thesystem offers a ‘semi-automatic’mode (absence detection),lighting manually (via a switch,a hand held controller or ascene plate), and the detectorwill switch or fade the lighting toleft the room. Both cases givethe possibility to dim the light toa minimum or a defined levelDimming response toincoming daylightSensaLink detectors providea dimming facility thatautomatically adjusts the lightlevel in response to the availabledaylight. You decide which lightlevel the controlling sensor shouldmaintain through the day, andif the sensor should switch thedaylight.Switching response toincoming daylightHere, dedicated SensaLinkheads, with relay output, switchthe ambient light level. Theseproducts come with an adjustablelight level.Local overrideinfra-red hand held controllerto override sensors that areresponding to the incomingdaylight – very convenient,especially in larger officeapplications, where you wantto change the lighting allocatedto one desk only, or to a groupof luminaires.

Parameter setting fortailor-made functionalityThis portfolio uses an infraredprogramming tool tore-programme a wide rangeof parameters, and to set theregulating light level. This isparticularly useful in that you areable to change the parameterswithout touching the installation,and is therefore fast, hassle-freeand doesn’t disrupt the roomusers: The programming is doneremotely and hence can beoperated from the ground.Maintainedilluminance levelLight levels reduce overtime due to lamp age anddirty optics. Conventionalinstallations provide morelight than is necessary toensure that the right level isreached when depreciation isworst. This results in energywastage and unnecessarycost. Being intelligent,the SensaLink detectorscontinually adjust the lightoutput and energy input. Thismaintains illuminance overthe entire period, saving theenergy that conventionalsystems waste and fulfillingthe objectives of manyinternational and locallighting standards.IlluminanceMaintenance intervalMaintenanceIlluminance in accordancewith age and soiling of lampRequired normal illumuminanceEnergy savings through dimmingof surplus capacity5

Overview of functions and their benefitsCorridorCorridorInteraction betweenluminairesSensaLink allows sensorsto be linked. In this way,sensors “listen” to eachother and share informationabout presence/absencewithin their detection zones.This feature is useful forexample in office applications;notional corridors, staircases,and lobbies can be set toremain lit as long as one ofthe sensors is detecting apresence, providing enoughlight in the surrounding areasand giving a feeling of safety(also known as ‘corridor hold’function).Interaction with room partitionsSome applications require larger rooms to be divided into smallerseparate rooms, depending on the activities. SensaLink detects if therooms are separated or linked, and reacts accordingly: If the partitionis closed, SensaLink provides individual control within each room. Ifthe partition is opened, the combined rooms offer joined control.CorridorReliability withdecentralised functionsSensaLink keeps local functionslocal. All parameters andsettings for a specific sensorhead are stored within the unit,therefore it will continue tofunction even if the Bus systemit is connected to fails or isinterrupted. The benefit is thatpresence and daylight-link, andlocal override functions arecontinuously provided, withoutthe room user realising the lossof the Bus system.Upgrade abilityAs the SensaLink sensor headsare able to work “stand-alone”when they are not connected toa central Bus system (see also‘Reliability with decentralisedfunctions’), the possibility arisesto install them first, and tolink them, via the SensaLinkBus, in a second phase. Bydoing this, the functionality ofthe installation would initiallybe similar to several ThornSensaDigital installations,working independently fromone another, and then in thesecond stage provide all theadditional SensaLink functions.In existing SensaLinkinstallations the Bus system alsoallows you to add additionaldevices and to extend thesystem at anytime. Thisprovides you with the flexibilitythat you would expect from acontrol system, adapting to thecontinuously changing needs,uses and room layouts within abuilding.6

System topology and components1) Starting with a multi sensor head for eachgroup of luminaires within an area…SensaLink responds to presence/absence by switching, and todaylight by dimming. Entering an area causes the lighting to cometo a pre-programmed level and the luminaires automatically adjustdepending on the natural light present.a) Thorn was among the firstcompanies to offer intelligentluminaires:incorporate a miniaturesensor capable of controllingelectronic gears, transformersand phase dimmers via a DSIsignal.Luminaire lies in the fact thatit works as soon as you takeit out of the box and installit to the ceiling. You can stillstandard mains switch, whichalso means you do not have tochange an existing installation.are possible as well, whereyou connect further luminaires(‘slaves’) to the DSI outputof the SensaLink Luminaire(‘master’). The maximumnumber of ballasts incorporatedin all controlled luminairesmust not exceed 4, andall luminaires should be inthe detection zone of theMiniSensaLink head (diameter5m at nominal mountingheight 2m above work plane,maximum mounting height 3m).Guides for Thorn SensaLink luminaires(containing ‘HFL’ in their descriptions). ‘Slave’luminaires for connection to the SensaLinkLuminaires are the standard DSI dimmableones (containing ‘HFD’ in their descriptions).MenloSoft SR with built-in MiniSensaLink headBUS2mHFLHFD5mHFDHFDOptional ‘Master-slave’ luminairearrangement (max. 4 DSI ballasts in total)Detection patternb) Remote SensaLink sensorheads enable you to control agroup of luminaires: insteadof having a ‘master-slave’arrangement as described ina). These remote sensor headsare mounted to the ceilingand control a luminaire groupincorporating up to 8 DSI ballastseach. These luminaires shouldbe in the detection zone of thesensor head (diameter 6m atnominal mounting height 2.4mabove work plane, maximummounting height 3m). You havethe choice between a recessedmounted version that is suitablefor unobtrusive installationin suspended ceilings ref.a surface mounted version forall other types of ceilings ref.The sensor incorporates a DSIoutput that is connected to the DSIdimmable luminaires via a 2-polepolarity-free lead. The maximumlength of the DSI lead betweensensor heads and luminaires canbe 12m, using standard mainswiring 2 x 1.5mm² with solidor stranded conductors, e.g.H05VV-U (harmonised standard300/500V cable, PVC insulatedand sheathed, with solidconductors).Note: All standard Thorn DSI dimmableluminaires can be controlled via remoteSensaLink heads: look for Thornluminaires containing ‘HFD’ in theInstead of controlling dimmableluminaires, there is also arecessed remote sensor head forswitching fixed output luminaires,for a maximum load of 6A,considering inrush currents ref.This sensor is connected tothe luminaires with standardmains wiring.Please refer to ‘Product parameters’for possible sensor settings.Please refer to ‘Product parameters’ forpossible sensor settings.8

System topology and components2) …linking these areas within rooms and floors…Within an application severalof these individually controlledareas can now be linked via theSensaLink Bus. To accomplish thistechnically, a two-wire Bus (mainsrated and unscreened twistedpair) runs from device to device,and a Bus power supply enablesthe devices to communicate witheach other and share occupancyinformation. SensaLink provides astandard Bus power supply for upup to 200 SensaLink devices ref.The Bus wiring topology canbe a ring with short spurs,radial or star like. The Bus leadmay also run alongside mainswiring, provided that the Busis suitably insulated. The mainstopology is independent from theBus topology, as the SensaLinkdevices can be mains poweredfrom different electrical circuitsand phases.HFDHFDHFLHFDHFDHFDHFLHFDHFDHFDExample for radial bus topology; maximum length of each radial 500m (300m) with 1 5mm 2 (1.0mm 2 ) conductor sizeHFDHFDHFDHFDHFDHFDHFLHFDHFDHFDHFDHFDHFDHFDHFDHFDHFLHFDHFDHFDHFDHFDSensaLinkBusMainsBUSPower Supply(LT or G)SensaLinkBusFor interconnecting all SensaLinkitems a bus lead is used: Themaximum length of this SensaLinkBus can be up to 1500m (if wiredas a ring), the cable should be1.5mm² twisted-pair unscreened.HFDHFDHFDHFDHFDHFDBUSPower Supply(LT or G)HFLHFDHFLHFDHFLHFDMainsHFDHFDHFDHFDHFDHFDHFLHFDExample for ring bus topology; maximum length of ring 1500m (800m) with 1 5mm 2 (1.0mm 2 ) conductor sizeStandard Bus power supplyBus power supply for larger applications10

5) Comissioning Tool 6) DSI and switching outputs,blind and screen control,switch inputs and interfaceto other systemsDigital ProgrammerUniversal Bus TransceiverThorn commissioning engineers set up SensaLink installations; thisservice is offered together with the luminaires and the SensaLink items.There is also the possibility to train contractors and facility managerson site, looking after the project later as well. Whoever commissions,reconfigures or changes SensaLink installations, uses the SensaLinkgroup them, to allocate control units to the groups and to define all theinteractions between the SensaLink devices. It is also used to configuretime and many others. Additionally it can be used to copy data fromone head and to use it for other ones. This device features a large LCDscreen to make it easy to use. And due to communicating via infra-redwith all the SensaLink devices, the commissioning can happen locallyand from the ground: This makes the work easy and safe, and doesnot disrupt any room users during reconfigurations.multi-functional and provides several features:incorporating up to 20 DSI ballasts, e.g. in an area where luminairesdo not need to be linked to presence or daylight.output luminaires (with magnetic or electronic gears) and non-lightingloads, e.g. screens and blackout blind motors, to be brought into theSensaLink installation.switch inputs into the system, e.g. from an external switch, timer, firealarm system or BMS, and can be configured to recall a specific All SensaLink sensors can be allocated to Global Groups: Thisgrouping structure is of less consideration to building users, but isof great importance for facility management, as it enables centraland external systems to override all sensor heads allocated to aGlobal Group. The SensaLink Transceiver is used as the interface tothese central systems: These could be central switches, or switchingBuilding Management Systems (BMS) or timers. Global Groupaddressing is typically used for load shedding, security, night andother functions.Sensor heads and SensaLink Transceiver inputs may be allocated toone of two possible Global Groups, or to both if required.system now knows if the rooms are separated or linked, and reactsaccordingly: If the partition is closed, SensaLink provides individualcontrol within each room.

Support of building compliance with European standardsOffice example, fully and partly occupied500lx500lx300lx300lxSensaLink supportsyour project to complywith EN 12464Norm 12464 differs from theclassical approach in which thelighting design objective wasto achieve average illuminancethroughout the room. Next tomany other criteria, the newstandard on the one handallows lighting designers greaterfreedom and designs that aremore in line with the needs ofindividuals, and on the otherdefines that lighting must bedelivered in the location wherepeople perform their visualtasks. Different maintainedilluminance levels apply forthe different work places, andthe surrounding areas wherevisual tasks are performedless often. For example fora 500lx task illuminance theimmediate surround illuminancecan drop down to 300lx.SensaLink maintains the specifiedilluminance levels, and alsochecks for you which areas areactually needed and occupied,and adapts the light output forthe unoccupied, but surroundingareas, according to the standard.SensaLink supportsyour project to complywith EN 15193This standard establishesconventions and proceduresfor the estimation of energyrequirements of lighting inbuildings. It also providesguidance on the establishment ofnotional limits for lighting energyderived from reference schemesand gives advice on techniquesfor separate metering of theenergy used for lighting that willgive regular feedback on theeffectiveness of lighting controls.Annex D (that is informative)recommends that (depending onthe application) an area withinone room, if it is illuminatedby a luminaire or by a groupof luminaires (manually orautomatically) switched together,should not be larger than 30m 2 .In addition, in the case of systemswith automatic presence and/or absence detection the areacovered by the detector shouldclosely correspond to the areailluminated by the luminaires thatare controlled by that detector.As lighting controls system basedon a network of multi sensorheads, SensaLink is the idealtool to realise the recommendedway of linking luminaires todaylight and presence/absencefor each area within a room,and therefore will support goodenergy ratings for your building.14

Product parametersTo adapt SensaLink to the local requirements, several parameters canbe set within each multi sensor head or SensaLink luminaire. These areselected during commissioning, and can be easily copied from onehead to the other to keep the commissioning time as short as possible.Power-up ConditionWhen mains power is firstapplied, sensor heads eitherfor up to 30s before lookingcorridors and access routes,other areas reduces the start-upload following any interruptionin supply.Operation ModeSet for automatic operation,the sensor head switchesautomatically. In semi-automaticmode (also called “absencemode”), luminaires remaineither via an user interface(e.g. the Infra-red hand heldController) or when anotherhead, part of the same zone, isStart LampsWhen detecting presence, lampsmaximum or minimum level,before ramping to the level thedaylight-link calculates, or thelevel set one for a recalled scene.When Vacantabove) has elapsed, lightingcan either be set to…Entry SceneAny one of the 6 availablescenes can be chosen to beactivated when presence isdetected. As scene 1 is thedaylight-linked scene, this is theDimming RangeThe daylight-link provided bya SensaLink sensor head willregulate over the full dimmingrange of the ballast’s capacity(typically between 100 and1%), to save as much energy aspossible. In certain instances aminimum light level can be set,avoiding the light level goingbelow a certain percentage.Set Light LevelThe luminaires are brightenedor dimmed until the desiredilluminance level is achieved. Thislevel is stored using the SensaLinkProgrammer. For luminaires withdimming ballasts, any lightinglevel within the operating rangeof the luminaire may be set. Thesystem automatically compensatesfor lamp deterioration andluminaire condition, andcontinually adjusts its light outputand energy input. This maintainsilluminance over the entireperiod, saving the energy thatconventional systems waste andfulfilling the objectives of manyinternational and local lightingstandards.Bright-outLights can be programmed toconditions, and to save evenmore energy. If Bright-out is notselected, the luminaire will simplyremain at minimum light outputuntil occupancy ceases or thedaylight contribution decreases.Off DelayThis is the time between the lastdetected occupancy, and whenthe lighting automatically ischanged to the chosen ‘WhenDelay options are 5 to 60min(in 5min steps), several hours,and 10s for test purposes duringcommissioning.Fade to Offluminaires dim very slowly (thefade rate is 4min/100%) beforerecommended in open-plan officecause distraction.sensor heads, provide somefurther parameters, which aredetailed in the datasheets.Following the installation ofSensaLink, the commissioning ofthe system and the setting of itsparameters is carried out locallyusing the hand-held infra-redSensaLink Programmer.
