2.2 MountingtheDetector
2.2.1 Positioning‐Thedetectorshouldbeinstalledsuchthatthecenterofthedetector’sfield‐of‐view
isaimeddirectlyatthecenteroftheareatobeprotected(hazardarea).Detectorsshouldbe
installedabovethehazardareapointingdownwardwithnoobstructionoftheField‐of‐View.



2.2.3 InstallationTips:‐Wheninstallingthedetectors,beawareofthefollowingconditions:
a) Ifdetectorsareinstalledinacompartmentcontainingchemicalbathsorheaters,care
shouldbetakennottoexceedthedetector’smaximumoperatingtemperature.
b) Field‐of‐Viewofdetectorsshouldnotbeblockedbyanyobjectsforoptimumperformance.
c) Detectorsshouldbeinstalledsuchthattherearenohighintensitylightsintheviewof
detectors.Highintensitylightsmaydiminishdetectorsensitivity.
d) Detectorsshouldbeinstalledsothattheyareeasilyaccessibleformaintenance.

3.0 Operation&Startup
3.1 DetectorPerformance&Response
TheD390isaMulti‐SpectrumInfraredfireandflamedetectordesignedfordetectionofHydrocarbon
andNon‐Hydrocarbonfires.Thedetectorincludes3separateQuantumIRsensorstunedpreciselyto3
separatebandsofIRradiationintheelectromagneticspectrumforrespondingtovarioustypesoffires.
ThedetectorelectronicsmoduleassemblyisencasedinasealedPolypropyleneenclosureandisoffered
withanintegralmulti‐conductorcablewithTeflonjacketsuitableforusinginharshandchemicalladen
environment.Detector’sresponsetoaflameisnormally3‐5secondsandtheresponsetimewilldepend
onthesizeoftheflameandthedistancefromtheflame.

3.2 DetectorOperation
Oncepoweredup,theD390detectorwillgothroughitsself‐diagnosticsprocessandwillbereadyfor
operationafter10seconds.Duringtheself‐diagnosticprocess,theGreen,Amber,andRedLEDswill
turnonsequentiallyindicatingthisprocess.Duringtheself‐diagnostics,theMicroprocessorwillcheck
thestatusofIRsensors,relays,variousdevices,andtheself‐testfeature.OncetheMicroprocessor
determinesthatalldevicesandfunctionshavebeentestedandfoundtobewithinthespecifications,it
willthenterminatetheself‐testdiagnosticsandwillreturnthedetectortonormaloperation.During
thenormaloperation,theGreenLEDwillbeturn“ON”for1secondand“OFF”for1secondindicating
thatthedetectorisnowreadytodetectfires.


DetectorSelf‐Test: 
TheD390detectorisprogrammedtoperformanautomaticdiagnosticself‐testperiodically
(factorydefaultisevery5minutes).DuringtheautomaticSelf‐Test,thedetectorwillturnon
bothAmberLEDsflashingfor2‐3seconds.FollowingtheautomaticSelf‐Test,thedetectorwill
returntoNormalOperationifnoFaultwasdetected.

3.3.5
DetectorOpticalPathTest: 
Thedetectoralsomonitorsthecleanlinessofitsviewingwindowandblockageofitsviewing
windoweverysecondusingtheOptiRadarfeature.Ifthecontaminationofthewindowexceeds
thepresetthreshold,thedetectorwilldeclareaFault.Thedetectoralsomonitorstheblockage
ofthewindowbyexternalobjects.Ifanobjectisplacedonthesurfaceofthewindow,the
detectorwillturnonitsAmberlightflashingfor60seconds;andiftheblockageisnotremoved
after60seconds,thedetectorwilldeclareaFaultbychangingtheflashingAmberlighttosteady
on.

4.0 Maintenance
4.1 InspectionandCleaning
Oncethedetectorhasbeeninstalledandpoweredup,itshouldprovidemaintenancefreeperformance
foryears.Thefollowingisasimpleguidelineforkeepingthedetectorfunctioningproperlyandtrouble
free:

4.1.1 TheD390detectorrequirednofieldcalibrationoradjustment.
4.1.2 ThedetectorisencasedinasealedPolypropyleneenclosurerequiringverylittlemaintenance.
However; in harsh chemical‐laden environment, dusty and oily places contaminant tend to
accumulateonthefrontviewingwindowthusreducingthedetectorsensitivity.Itistherefore
recommendedtocheckthedetectorandcleanthefrontsurfaceasneededwithsoftcottoncloth
andIPA(IsopropylAlcohol).Priortocleaningthefrontviewingwindow,itisrecommendedto
disconnectpowertodetector.
4.1.3 ThedetectorisfittedwithaTefloncablecompressionfittingandtightenedtopropertorquefor
maintainingtheintegrityofleak‐proofenclosure.UndernocircumstancetheTefloncompression
fittingshouldbeadjusted.Ifthefittingbecomesloose,please either return the detector to
factoryforthefittingtobere‐torquedorcallthefactoryforexacttorquesetting.

4.2 PeriodicTesting
The detector should also be functionally tested end‐to‐end annuallyorasrequiredbylocalcodesor
authoritieshavingjurisdiction.Priortotestingthesystem,alldetectoroutputstoFireAlarmPanelor
extinguishingsystemsshouldbedisabledordisconnected.Thefunctionaltestshouldbeperformedby
qualifiedpersonnelbeingfamiliarwiththesystem.
