Functional Description
Initialisation:
Whenthedetectorisswitchedon,its
LEDindicatorblipsontosignifypower
up.Duringthefirst10secondsthe
detectorperformsautocalibrationto
establishthequiescentobscurationlevel.
Please note:Itisimportantthatthe
beampathisclearedtoahealthystate
(noobscuration)priortoresettingthe
detector.Ifthebeampathisnothealthy,
thedetectorwillrecalibratetothe
currentlevelofobscurationinturn
reportingfalsealarm/faultconditionsas
thepathclears.Ifobscurationishigh(dir-
tylensesoroil/smokeispresent)then
thedetectorwillnotbeabletoestablish
operationalstateandwillreportaclean
fault(LEDpulsesonfor4sec)oralife
fault(LEDisilluminatedcontinuously).
TheP-UIMwilllatchthefaultcondition
andthedetector/P-UIMwillrequire
resetting.
Alarm Level Detection:
Thedetectormonitorstheobscuration
levelwithinthebeampathandwhenit
detectsalossof0.5dBitlatchesalow
levelalarmcondition.Ifthelossis
maintainedwithinthe0.5to<1.5dB
bandduringthesubsequent15second
alarmmonitoringperiod,alowlevel
alarmwillthenbereported(LEDwill
pulseOn/Offfor30seconds).Iftheloss
exceeds1.5dBthenahighlevelalarmis
latchedandthisstatuswillbereported
(LEDpulsesOn/Offfor2minutes)atthe
earliest8secondsfromthebeginningof
thealarmmonitoringperiod.Ifthehigh
leveloccurssubsequenttotheinitial8
secondofthealarmmonitoringperiod
andbeforeatotalof15secondshas
elapsed,thehighlevelalarmwillbe
latchedandreportedimmediately.Please
Note:Iftheleveloflossduringthealarm
conditionmonitoringperiodfallsbelow
0.5dB,thelatchedalarmlevelwillreset
andthedetectorwillcontinuetomonitor.
Beam Block:
Ifthelevelofobscurationincreases
suddenlytoahighleveloflossabeam
blockedstatuswillbelatchedandifthe
levelismaintainedfor60seconds,Beam
Blockedwillbereported(LEDflashesON
for2seconds).Ifthebeamblockedlevel
ofobscurationclearsformorethanafew
secondsduringthe60secondperiod
monitoringperiod,thedetectorwill
returntoitsnormaloperatingstate.
Dual Automatic Compensation:
Thedetectorautomaticallycompensates
forgradualdetectorlenscontamination
andalsocompensatesforthemorerapid
environmentalchanges(eg.Temperature
Change).Thedetectorwillreportaclean
fault(LEDFlashesonfor4seconds)
once.Ifthedetectorisnotcleaneditwill
continuetooperateuntilalifefaultis
detected(LEDonsteady)atwhichpoint
thedetectorlatchedtoanoffcondition.
Thedetectormustbecleanedandreset
oncethelifefaulthasbeendetected.
Installation Procedure
Toinstallthedetector,findan
unobstructedpath,ideallyabovehead
heightthatcoverstheareatobe
monitored.Whenchoosingthebeam
paththedirectionofanyprevailingair
currentsshouldbenotedtoassessthe
directionthatanyoilmistwouldbe
conveyed.
Itshouldbenotedthatthebeammust
notbewithin500mmofanywallor
partition.Theoperatingrangeis2-50
metres.
Thereflectorsheetmustbemountedon
aflatsurface(selfadhesivebacking)such
thatthedetectorandreflectorare
alignedhorizontallyandvertically.To
assistinthisprocedureatoolisavailable
(01-33-21)toensurethedetectorbeamis
focusedcentrallyonthereflector.The
alignmenttoolintensifiestheIRbeam&
convertsitsimagetovisiblelight.Dueto
thenatureofoperationofthealignment
tool,itisrecommendedthatitshould
usedinsubduedlightconditions.The
physicsofthereflectorconstruction,
enablethereflectortobeupto10
degreesoutofalignmentinanyone
planeasdetailedinthefollowing
