1)Introduction
TheBExCS110-L1Disaflameproofcombinedsounder / LED
beaconwhichiscertifiedmeettherequirementsof theATEX
directive94/9/ECandtheIECExScheme. Thecombined unit
producesbothloudaudiowarningsignalsandvisualwarning
signalsthatcanbe used inhazardousareaswhere
potentiallyflammableatmospheres may be present. Thirty-
twodifferentfirststage audioalarmsoundscan be selected
byinternalswitches,andeachonecan be externally
changed toasecondorthirdstagealarmsound(seetone

6) Location andMounting
Thelocationoftheunit shouldbemadewithdueregardto
theareaoverwhichboththesounderandbeaconwarning
signalmustbeaudibleandvisible.Theunit shouldonlybe
fixed toservicesthat cancarrytheweight oftheunit.
Theunit shouldbesecurelyboltedtoasuitablesurfaceusing
the7mmdiameterboltholesinthestainlesssteelUshaped
mountingbracket(see figure1). Theanglecan thenbe
adjusted inthedirectionsuchthatitswarningsignalscan be
bothheardandseen.Thiscan be achievedbylooseningthe
twolarge bracketscrewsintheside oftheunit, whichallow
adjustmentinstepsof 18°.Oncompletionoftheinstallation
thetwolarge bracketadjustmentscrewsonthesideofthe
unitmustbe fullytightened toensurethattheunitcannot
moveinservice.
7) SafetyWarning (ElectrostaticHazard)
TheacoustichornsectionismadeofABSPlastic,therefore
toavoidapossibleELECTROSTACTICCHARGEtheunit
must onlybe cleanedwithadampcloth.
8) Access to theFlameproofEnclosure
Inordertoconnecttheelectricalsupplycablestothe unit it is
necessarytoremovethebeaconsectiontogainaccess to
theflameproof chamber. To achievethisremovethefourM6
hexagonsocketheadscrews(see figure2)andwithdrawthe
beaconsectiontakingextremecarenottodamagethe
flameproofjointsintheprocess.
Notethefour M6screwsareClass A4-80 stainlesssteel
andonlyscrewsofthiscategorycanbeusedonthese
units. Itisthereforeimportantthatthese screwsandtheir
springwashersarekept inasafeplaceduringinstallation.
Oncompletionofthecablewiringinstallationtheflameproof
jointsshouldbe inspected toensurethattheyareclean and
thattheyhavenotbeendamaged duringinstallation.Also
checkthattheearthbondingwirebetweenthetwocasting
sectionsissecureandthe‘O’ringsealisinplace.When
replacingthebeaconsectioncasting,ensurethatit issquare
withthesounder sectionchamber castingbeforeinserting.
Carefullypushthebeaconsectioninplace allowingtimefor
theairtobe expelled. Onlyafter thebeaconsectioncastingis
fullyinplace shouldthefour M6Stainless Steel A4-80cover
boltsandtheirspringwasherbeinsertedandtightened
down.If thebeaconsectionjamswhileit isbeinginserted,
carefullyremoveit andtryagain.Never use thecover boltsto
force thebeaconsectioncastingintoposition.
Incaseof repair, contactthemanufacturerforinformationon
thedimensionsoftheflameproofjoints.
