WARNING
Thefollowingprocedurerequiresthedetectorcovertoberemovedwhilecarryingout
supplyvoltagechecks.Thereforetheappropriatepermitstoworkshouldbesoughtin
preparation.PriortocarryingoutanyHOTWORKensurelocalandsiteproceduresare
followed.Ensurethattheassociatedcontrolpaneloutputactuationisinhibitedsoasto
preventfalsealarms.
Caution:Thefollowingprocedureshouldbefollowedcarefullyandonlyperformedby
suitablytrainedpersonnel

1. Removethedetectorcover
2. Makesurethedetector'soutputandpowerinputconnectionsdonecorrectly
3. Checkthatallelectricalconnectionsareterminatedcorrectly
4. SwitchOntheexternalpowersupplytofeedthedetector.IfitisconnectedtoDP32
Panel,cablesshouldbeinstalledaccordingtoDP32Panelusermanualaspanelcan
providebothpowerandcommunicationconnectionstothedetectors.
5. UsingaDigitalMultiMeter(DMM),checktheSupplyVoltageattheterminalsV+andV‐
thisshouldbeaminimumsupplyvoltageof12VDC(Maximumsupplyvoltageis24VDC).
6. CheckLEDstatusondetectormainboard.LEDstatusshouldbelikeexplainedabove
afterapplyingpower.
7. WaittwominutesandconfirmdetectorLEDstatuspointingnormaloperation.If
detectorsusedwithDP32Panel,panelshouldrecogniseeachdetectorcorrectlyattheir
addresses.
8. SwitchOfftheexternalpowertothedetector.
9. Fitthecoverandmakesurenonofthecablescauseanobstructionwhilefittingcover
10. Switchonexternalpowertothedetectororpanelifused.

Calibration
Itisrecommendedtoperiodicallycarryoutcalibrationtoensurecorrectoperation.
Calibrationshouldbedonebyapersonwhotrainedandcertifiedbylocalorinternational
authorities.
Detectorshouldbepoweredandstabilizedforatleast30minutesbeforecalibration.To
calibratethedetector,useanappropriatespangascylinder,constantflowregulatorand
ProsenseGasCap.Theflowrateusedforcalibrationgasis0.5L/Min.
ZeroCalibration
Itisrecommendedtouseacompressedaircylinder(20.9%Voloxygen)toperformthezero
calibrationiftheareawherethedetectorislocatedcontainsanyresidualamountofthe
targetgas.Ifnoresidualgasispresentthenthebackgroundaircanbeusedtoperformthe
zerocalibration.ToperformZerocalibrationputajumpertoZpinsondetectormainboard
andpressZerobuttonfor3seconds.Thezerolevelwillbeautomaticallyadjusted.
SpanCalibration
AsthereisonlyrelayoutputsandRS485communicationportsavailableondetectoritis
necessarytouseacontrolpaneltoseegasmeasurementofthedetectorduringthespan
calibration.IfRS485communicationisnotpossiblecalibrationshouldbedoneinaservice
center.ToperformSpancalibrationapplygastodetectorviausingtheGasCapwhile
detectorisenergisedandworking.Thesignallevelvarydependingontheusedgasfor
calibrationandgasconcentration.Ifthemeasuredlevelislowerthanthecalibrationgas
level,putajumpertoS+pinpresstoSpanbuttontillthelevelreachesthenecessarlyvalue.
Ifthemeasurementlevelishigherthanthenecessaryvalue,putajumpertoS‐pinand
presstoSpanbuttontillthelevelreachesthenecessarlyvalue.Oncethespancalibration
completedremovethejumperandputasaspareontodetectorboard.
Important:NeverputjumperonbothS+andS‐pinsandpressanybutton.
