
4DESIGNDESCRIPTIONS
TheDOT‐4046detectorisequippedwithtwosensorsthatdetecttwofirefactors:heatandsmoke.
Heatisdetectedbyatemperature‐sensitiveresistor(thermistor)whereassmokeisdetectedbya
specialopticalmoduleconsistingofalighttransmittingdiodeandareceivingone.Theyaremounted
insuchawaythatthelightemittedbythetransmittingdiodedoesnotreachtheotherdiode
directly;alabyrinthprotectsthediodesfromexternallightinterference.Ametalprotectivenet
preventsthedetectorfromirruptionofsmallinsectsorpiecesofdirt.Thewholestructureisplaced
inawhiteplastichousing.

5PRINCIPLEOFOPERATION
TheDOT‐4046detectoroperationbasisisTyndalleffect–lightrayscatteringonsmokeparticles.
Whensmokeparticlespenetratethemeasuringchamber,theyreflectthelightemittedbythe
transmittingdiode.Thereflectedlightreachestheopticaldiodeproducingphotocurrent.Theheat
enteringthedetectorevokesthethermistorresistancechange.Informationaboutfirefactors
deliveredbybothsensorsarethoroughlyanalysedbythemicroprocessorthatevaluatesafirehazard
level.
CommunicationbetweenthePOLON4000systemfirealarmcontrolpanelandtheDOT‐4046
detectorsisprovidedthroughatwo‐wireaddressabledetectionline.Aunique,fullydigital
communicationsprotocolenablespassinganyinformationfromthecontrolpaneltothedetector
andinversely,e.g.evaluationofsurroundingconditions(smokiness,temperature),tendencyofits
changeaswellascurrenttemperatureanaloguevalueandsmokinessdensity.
Thedetectoroperationcontrollingmicroprocessormonitorscorrectnessofitsbasiccircuits
operationand,incaseanirregularityisfound,deliversrelevantinformationtothecontrolpanel.
TheDOT‐4046detectorisananaloguedetectorwithdigitalself‐regulationmechanism,i.e.it
maintainsconstantsensitivityduringthemeasurementchambercontaminationprogress.Incasea
settledtechnicalalarmthresholdisexceeded,thedetectorsendsinformationtothepanelofthe
measurementchamberpartialcontaminationinordertoinformserviceteamsofanecessityto
undertakeappropriateactions.
Thedetectorisequippedwithaninternalshortcircuitisolatorthatcutsoffanefficientdetectionline
fromtheneighbouringshortedsectionwhatenablesfurtherundisturbeddetectoroperation.
Analarmmodeisindicatedwithapulseredlightemittedbyanilluminatingdiodeinstalledinthe
detectorcasing.Theindicatorenablesfastlocationoftheactivateddetectorandishelpfulinperiodic
detectorinspections.Incasethedetectorishardlyvisibleorisinstalledinadifficult‐to‐reachspace,
anadditionalopticalalarmindicator(WZ‐31)maybeconnectedinanaccessibleandvisibleplace.
Afaultmode,atechnicalalarmandanactuationofashort‐circuitisolatoraresignalledwithyellow
flashesofthediode.

6DETECTOROPERATIONMODES
Detectorisfurnishedwithfourbasicoperationmodes(apartfromalarmvariantsinthecontrol
panel)thatenablethebestadjustmentofitscharacteristicstogivenoperationenvironment:
‐‘1’mode ‐ multi‐criteria,equivalenttointeroperationoftwosmokedetectors(DOP)
andtwoheatdetectors(TUP)inA1Rclass;
‐‘2’mode ‐multi‐criteria,equivalenttointeroperationofasmokedetector(DOP)anda
heatdetector(TUP)inBRclass;
‐‘3’mode ‐ independent,equivalenttoindependentoperationoftwodetectors,
providingthesamesuitabilityasDORdetectorandTUPdetectorinA1Rclass.
Thissetupsensurehighfalsealarmresistanceatlowersensitivityasin‘1’
mode.InthismodeaDOR‐4046detectorsubstitutestwodetectorsand
eliminatesanecessitytoinstallDOR‐4046andTUP‐4046detectorsinA1R
classsidebyside;
‐‘4’mode ‐ independent,equivalenttoindependentoperationoftwodetectors,
providingthesamesuitabilityasDORdetectorandTUPdetectorinBRclass.
Thissetupensureshighfalsealarmresistanceatlowersensitivityasin‘2’
mode.InthismodeaDOR‐4046detectorsubstitutestwodetectorsand
eliminatesanecessitytoinstallDOR‐4046andTUP‐4046detectorsinBRclass
sidebyside.
Additionally,thedetectorprovidesapossibilitytoprogramthreemodesintendedforparticular
detectoroperationdiagnostics:
‐‘5’mode ‐inwhichonlyasmokedetector(DOR)operates;
‐‘6’mode ‐inwhichonlyaheatdetector(TUP)inclassA1Roperates;
‐‘7’mode ‐inwhichonlyaheatdetector(TUP)inclassBRoperates.
7OPERATIONANDSERVICINGCONDITIONS
Duringthedetectorsoperationitisobligatorytoavoidcreationofdeworrimeonthedetector
surfaceaswellastoprotectagainstexcessivecontaminationwithdust.
Fortheperiodofrepairworks,thedetectorshouldbetakenoutorprotectedwith
appropriateforthispurposecover.Suchacovercanbeobtainedfromaninstalleror
purchasedfromthemanufacturer.Incasethedetectoristakenout,itsbaseshouldbe
protectedagainstbeingpaintedutilisingapaintingtape.Detectorswhicharedamaged
duringpaintingandrenovationworksduetoafaultofthepersonsexecutingsuchworks
(e.g.painteddetectorcasing,stuck‐with‐paintnet,etc.)arenotsubjecttowarrantyrepairs.
TheDOT‐4046addressablemulti‐sensordetectorshouldbesubjectedtoperiodicalinspection
accordingtoPKN‐CEN/TS54‐14:2006standard,whichisexecutedinordertoconfirmthedetector
properoperationanditsappropriateinteroperationwiththecontrolpanel.Theinspectionshouldbe
carriedoutatleastoncein6months.
Thesmokesensoroperationshouldbetestedusingasmokesimulator(emittingnoheat)and
afterwardstheheatsensorshouldbetestedusingaheatimitator(generatingnosmoke).
TheDOT‐4046detectorlong‐lastingoperationmayresultindustaccumulationinsideitssmoke
sensor.Afterexceedingtheself‐regulationrangeduetothesmokesensorcontaminationprogress,

Adelicatebrushaswellasvacuumcleanerarerecommendedforcleaningworks.Compressedaircan
bepossiblyused.Itispermittedtowashthelabyrinthwithwarmwaterwithadditionofwashing‐up
liquid.Nodamppatchesshouldremainonthelabyrinthinternalsurfacesafterwashinganddrying.

IK‐E301‐001GB7
Aftercleaningthedetectorshouldbeassembled.Inordertodoit,itisnecessaryto:
a) fastenthelabyrinthwithtwoscrews;
b) locatethermistorbasisplacingthethermistorleadsintothelabyrinthnotches;
c) laydownthebasketinthepositionasshownonthefigure;
d) insertthemaskinggridintothebasketpayingattentiontoitspositioning–alignmentwith
