BExL25DandBExL15DFlameproofLoudspeakers
1)Introduction
The BExL25D andBExL15D areflameproof loudspeakers
whicharecertified tomeettherequirements of theATEX
directive94/9/EC andtheIECExscheme.Theloudspeakers
canbeused in hazardousareas wherepotentially flammable
atmospheres maybepresent.There are four versions ofeach
loudspeaker,8ohm or16 ohm and70Vor100VLine
transformer.On 70Vand 100V line transformerunits there are
fouroutputtappings for eachsize of loudspeaker.The
BExL25Dunit producesoutput levelsin the117dB(A)range
and the BExL15Dunit producesoutputlevelsinthe112dB(A)
range.Bothloudspeakers canbe usedin Zone 1 andZone 2
areaswithgasesin groupsIIA,IIB andIICandtemperature
ClassificationsofT1,T2,T3andT4. For ambient temperatures
over +55ºCthegasgroupsare limited toIIA and IIB.

4) InstallationRequirements
The loudspeakersmustbe installedin accordance withthe
latestissuesof the relevant parts ofthe EN60079standards or
the equivalent IEC standards–Selection, Installationand
maintenanceof electrical apparatusforuse in potentially
explosiveatmospheres(other thanminingapplicationsor
explosiveprocessing and manufacture):-

The installationof theunitsmustalsobe in accordance with
anylocal codesthat may apply and should onlybe carried out
by a competent electrical engineerwho has had thenecessary
training.
5) Zones,GasGroup,Categoryand Temperature

6) LoudspeakerLocationand Mounting
The locationoftheloudspeakersshouldbemade withdue
regardtotheareaoverwhich the unitmustbeaudible. The
loudspeakersshould onlybefixedto servicesthatcancarry
the weight ofthe unit.
The loudspeakersshouldbesecurely bolted to asuitable
surface usingthe 7mmdiameter boltholesinthe stainlesssteel
Ushaped mounting bracket(seefigure 1). Theanglecanthen
be adjustedin thedirection that the soundis primarily required
tocover. Thiscan be achievedbyloosening thetwo large
bracketscrews in the side of the unit, which allowadjustment
in steps of 18°. Oncompletion of the installation the two large
bracketadjustment screwsontheside of the unit mustbe fully
tightenedto ensurethat theunit cannotmovein service.
7) SafetyWarning (ElectrostaticHazard)
The acoustic horn sectionis made of ABSPlastic,therefore to
avoidapossibleELECTROSTACTIC CHARGEthe unitmust
only be cleanedwith a damp cloth.
8) Access totheFlameproofEnclosure
Inorder toconnectthe audiosupply cables to the loudspeaker
it is necessary to removetheflameproofcovertogain access
totheflameproofchamber. To achieve thisremovethefour M6
hexagon sockethead screws (see figure2) andwithdrawthe
flameproof cover takingextremecarenotto damagethe
flameproof joints in theprocess.
Notethefour M6screwsareClassA4-80stainlesssteel
and onlyscrewsof thiscategorycanbeused on these
loudspeakers. It istherefore importantthatthese screwsand
their springwashersarekept in a safe place duringinstallation.
Oncompletionof thecable wiring installationtheflameproof
jointsshould be inspectedto ensurethat theyarecleanand
thatthey havenotbeen damagedduringinstallation.Also
checkthat theearthbonding wirebetween thetwocasting
sectionsissecureandthe‘O’ringseal isinplace.When
replacingtheflameproof cover casting ensurethat itis square
withthe flameproof chamber castingbefore inserting. Carefully
push thecoverin placeallowing timefor theair to be expelled.
Only afterthecover isfullyinplace,should the fourM6
Stainless SteelA4-80 coverbolts and theirspringwashers be
insertedand tighteneddown. If the coverjamswhile it isbeing
inserted, carefully remove it andtry again.Never use thecover
boltsto force the cover intoposition.
9) PowerAmplifierSelection
Itisimportant thattheloudspeakersareconnectedtopower
amplifiersthat haveoutputsthat arecompatibletothetype of
loudspeakerbeingused.Loudspeakerswith a70Vor100V
line matching transformerfitted mustbeconnected to apower
amplifier with a70Vor100Vline output.Lowimpedance 8
ohm or16 ohmloudspeakers must beconnected to amplifiers
withasuitablelowimpedance output. Whenselectingthe
cable size considerationmustbegivento thecurrentthateach
unitdraws,thenumberofloudspeakerson thelineandthe
length ofthe cablerun.
The followingtableshows therangeofloudspeakers:-

The above tablealso showsthe maximum ACsignalvoltages
at whichthe loudspeakers canbe operated.
The currentlevelstakenbytheeachloudspeakerwill depend
onwhich output tapping hasbeenselected (see section13 of
this instructionmanual). BExL25D 70Vand100VLine units
have outputlevels of 25W, 12.5W, 6W and 2W;BExL15D 70V
and 100VLine unitshave output levels of15W,7.5W,3W and
1W.

11) Earthing
All loudspeakers mustbe connectedtoagood quality earth.
The unitsareprovidedwithinternal and externalearthing
terminalswhichare bothlocatedonthe flameproofcover
sectionoftheunit (seefigures 2and3).
When using theinternal earth terminal ensurethat the
stainlesssteel M4flat washerisbetween theincomingearth
wireand the enclosure.
Whenusing theexternal earthterminalacablecrimp lug must
be used. Thecablelugshould be located between thetwoM5
stainlesssteelflat washers.The M5 stainlesssteelspring
washermust befixedbetween theouterflat washer andthe
M5 stainlesssteelnutto ensurethat thecable lug is secured
againstlooseningand twisting.
The internalearthbondingwireensures that agoodquality
earth is maintained betweentheflameproofchambercasting
and the flameproofcovercasting.
12) CableGlands
The BExL25DandBExL15Dloudspeakershavedual cable
glandentries whichhaveanM20 x1.5entry threadas
standard.Onlycable glands approvedforEx‘d’applications
canbe used, which mustbe suitablefor the type of cable being
usedandalsomeetthe requirements ofthe Ex‘d’ flameproof
installation standardEN60079-14:2008 / IEC60079-14:2007.
SAFETY WARNING: Iftheloudspeakers are usedathigh
ambienttemperatures,i.e.over+40ºC, thenthecable entry
temperature mayexceed +70ºCand thereforesuitable heat
resistingcableglandsmustbeused, with aratedservice
temperature of at least 110ºC.
Ifahigh IP (Ingress Protection)ratingisrequired thena
suitable sealingwasher mustbe fitted under the cablegland.
Whenonly one cable entry isusedtheotherone mustbe
closed with an Ex ‘d’flameproofblankingplug,which mustbe
suitablyapprovedfortheinstallation requirements.
13) CableConnections
The cableconnectionsaremadeinto theterminal blockson
the pcb assembly locatedinthe flameproofenclosure. See
section8ofthismanual foraccess totheflameproof
enclosure. The70V and100V Line loudspeakers are fitted with
afiveway terminal block.TerminalAiscommonandoneof

A singlewire withacross sectionalarea ofup to 4mm² can be
connectedto eachterminal way or ifaninput andoutputwire
isrequired two 2.5mm²wires can be connectedtoeach

care should be takento dress thewire so that whenthecover
isinsertedintothechamberthe wiresdo not exert excess
pressureonthe terminal blocks.Thisis particularlyimportant
whenusing cableswith largecrosssectional areas suchas

14) EndofLineDC Monitoring
OnBExL25DandBExL15D loudspeakers,dclinemonitoring
canbe used if required. Both the 70V and 100V Line units and
the LowImpedanceunitshaveblockingcapacitorsfitted.It
should be notedthateach loudspeaker hasa1Mohm bleed
resistorconnectedacrosstheblockingcapacitorand this
should be takeninto account when selectingthevalue of the
end oflinemonitoring resistance.
The endof linemonitoringresistor canbeconnectedacross
the terminalsonthe end of lineunit.Onthelowimpedance
unitscaremustbe taken withthepolarityof themonitoring
voltage.
On100V and 70V line units the end of line resistor usedmust
have a minimum resistancevalueof 4k7ohms and aminimum
wattage of 2.5watts
Onlowimpedance units the end of lineresistorusedmust
haveaminimum resistancevalue of2k ohmsandaminimum
wattageof 0.5watts oraminimumresistancevalueof500
ohmsandaminimumwattageof2watts.Onthe low
impedanceunits caremustbetakenwiththepolarity of the

the links on the printed circuit boards of all loudspeakers in the
line must be cut for thedc blocking capacitorsto bein circuit in
order to dc monitor theline(seefigure5).
