FlameproofCombined Sounder/Beacon
1)Introduction
TheBExCS110-05Disasecondgenerationflameproof
combinedsounder/beaconwhichiscertifiedtothe
European StandardsEN50014:1997 andEN50018:2000
andmeetstherequirementsoftheATEX directive94/9/EC.
Thesoundersectionproducesloudaudiowarningsignals
andthebeaconsectionproducesasynchronisedvisual
warningsignal.Theunitcan be usedinhazardousareas
wherepotentiallyflammableatmospheresmaybepresent.
Thirty-twodifferentfirststage audioalarmsoundscan be
selected byinternalswitches, andeachonecan be externally
changed toasecondorthirdstagealarmsound(seetone
tableon Page5).Thesounderproducesoutputlevelsinthe
110dB(A)range andthebeaconproducesan outputlevelof
5joules.Theunitcanbe usedinZone1andZone2areas

6) Location andMounting
Thelocationoftheunitshouldbemadewithdueregardto
theareaoverwhichboththesounderandbeaconwarning

fixed toservicesthat cancarrytheweight oftheunit.
Theunitshouldbesecurelyboltedtoasuitablesurfaceusing

adjusted inthedirectionsuchthatitswarningsignalscan be
bothheardandseen.Thiscan be achievedbylooseningthe
twolarge bracketscrewsintheside oftheunit, whichallow
adjustmentinstepsof 18°.Oncompletionoftheinstallation
thetwolarge bracketadjustmentscrewsonthesideofthe
