FlameproofCombined Sounder/Beacon
1)Introduction
TheBExCS110-05Disaflameproofcombinedsounder/
beaconwhichiscertifiedtomeettherequirementsofthe
ATEX directive94/9/EC andtheIECExscheme. Thesounder
sectionproducesloudaudiowarningsignalsandthebeacon
sectionproducesasynchronised visualwarningsignal. The
unit canbe usedinhazardousareaswherepotentially
flammableatmospheresmay be present. Thirty-twodifferent
firststageaudioalarmsounds can be selected byinternal
switches,andeachonecan be externallychanged toa
secondorthirdstagealarmsound(seetone tableonPage
5). The sounderproducesoutputlevelsinthe110dB(A)
range andthebeaconhasaflashenergyof5joules. Theunit
can be usedinZone1andZone2areaswithgases in
groupsIIAandIIBandwithTemperatureClassifications of
T1, T2, T3 andT4.

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
