FlameproofLoudspeakers
ForuseinFlammableGasandDustAtmospheres
1)Introduction
The BExDL25D and BExDL15D areflameproofloudspeakers
whicharecertifiedto the meet the requirementsof the ATEX
directive94/9/ECandIECExscheme.The loudspeakerscan
beused in hazardousareaswherepotentially flammablegas
and dustatmospheresmaybe present. Therearefour
versionsofeachloudspeaker, 8 ohmor16ohmand70Vor
100V Line transformer. On70Vand 100Vlinetransformer
unitsthere are four outputtappings foreachsizeof
loudspeaker. TheBExDL25Dunit produces output levels in the
117dB(A)rangeand theBExDL15Dunit producesoutput
levelsinthe 112dB(A) range.Bothloudspeakerscanbe used
in Zone 1 and Zone 2areaswith gasesin groups IIA,IIB and
IICand temperature Classifications ofT1,T2,T3andT4.For
ambient temperaturesover +55ºCthegasgroupsare limited to
IIAand IIB.They canalso beused inZone21andZone 22
areas for combustible dusts and have anIP rating of IP67 and
asurfacetemperaturerating ofT100ºCup to+55ºCand
T115ºC over +55ºC.

6) LoudspeakerLocationandMounting
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 sound is 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) AccesstotheFlameproofEnclosure
Inorder toconnectthe audiosupply cables to the loudspeaker
it is necessary to removetheflameproofcovertogain access
totheflameproofchamber. To achievethisremovethefour M6
hexagon sockethead screws (see figure2) andwithdrawthe
flameproof cover takingextremecarenotto damagethe
flameproof joints in theprocess.
Notethefour M6screwsareClass A4-80stainless steel
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
sections issecureandthe‘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.
8) PowerAmplifierSelection
Itisimportant thattheloudspeakersareconnectedto power
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 currentlevelstakenbytheeachloudspeakerwill depend
onwhich output tapping hasbeenselected (see section13 of
this instructionmanual).BExDL25D70Vand100VLine units
haveoutputlevelsof 25W,12.5W,6Wand2W;BExDL15D
70V and 100VLine unitshave output levels of15W,7.5W,3W
and 1W.
9) CableSelection
Whenselecting the cable size consideration mustbegivento
the current that eachunit draws,thenumberofloudspeakers
onthelineandthelengthof thecableruns.
SAFETY WARNING: Iftheloudspeakers are usedathigh
ambienttemperatures,i.e.over+40ºC, thenthecable entry
temperature mayexceed +70ºCand thereforesuitable heat
resistingcables mustbeused,witharatedservice
temperature of at least 110ºC.
10) Earthing
All loudspeakers mustbe connectedtoagood quality earth.
The unitsareprovidedwithinternal and externalearthing
terminalswhichare bothlocatedonthe flameproofcover
sectionoftheunit (seefigures 2and3).
Whenusingtheinternal earth terminalensure thatthe
stainlesssteelM4flat washer isbetweentheincoming earth
wireand the enclosure.
Whenusing theexternal earthterminalacablecrimp lug must
be used. Thecablelugshouldbe 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.
11) CableGlands
The BExDL25DandBExDL15D loudspeakers havedualcable
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 standardEN 60079-142008 / IEC60079-14:2007.
Whenonly one cable entry isusedtheotherone mustbe
closed with an Ex ‘d’flameproofblankingplug,which mustbe
suitablyapprovedfortheinstallation requirements.
For combustibledust applications, the cableentry deviceand
blanking elementsshall be in type of explosionprotection
increasedsafety"e"or flameproof enclosure "d"andshall have
an IP 6Xratingaccording toEN60529:1992.
SAFETY WARNING: Iftheloudspeakers are usedathigh
ambienttemperatures,i.e.over+40ºC, thenthecableentry
temperature mayexceed +70ºCand thereforesuitable heat
resistingcableglandsmustbeused, with aratedservice
temperature of at least 110ºC.
12) CableConnections
The cableconnectionsaremadeinto theterminal blockson
the pcb assembly locatedinthe flameproofenclosure. See
section7ofthismanual foraccess totheflameproof
enclosure. The70V and100V Line loudspeakersare fittedwith
afiveway terminal block.Terminal Aiscommonandoneof
the other terminals B, C, DorE should beselecteddepending
onwhat output level isrequired(seetablebelow).

A singlewire withacross sectionalarea ofup to 4mm² can be
connectedto eachterminal way or ifaninput andoutputwire
isrequired two 2.5mm²wires can be connectedtoeach
terminalway.Whenconnectingwirestotheterminalsgreat
care shouldbe takento dress thewireso that whenthecover
isinsertedintothechamberthe wiresdo not exert excess
pressureonthe terminal blocks.Thisis particularlyimportant
whenusing cableswith largecrosssectional areassuchas

13) End ofLineDCMonitoring
OnBExDL25D andBExDL15Dloudspeakers,dc line
monitoringcan beusedifrequired.Both the70Vand 100V
Lineunitsand the Low Impedance unitshave blocking
capacitors fitted.It should benoted thateachloudspeakerhas
a1Mohm bleed resistorconnectedacross the blocking
capacitorand this should be takeninto account whenselecting
the valueof theendoflinemonitoringresistance.
The endof line monitoringresistor 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
monitoringvoltage.Ifan end oflineresistor is fitted to aunit
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).
