ForuseinFlammableGasandDustAtmospheres
1)Introduction
The BExDTS110Dis aflameproofSonteltelephonesounder
whichiscertifiedtomeettherequirementsoftheATEX
directive 94/9/ECandIECExscheme.The Sontelproduces a
loudaudible signal when triggeredby atelephoneringing
signal andcanbeused in hazardous areaswhere potentially
flammablegas and dustatmospheresmay be present. Thirty-
two differentsounds can be selected by internalswitches(see
tone tableonPage 4).TheBExDTS110Dunitproduces
output levelsin the110dB(A)range.Theunitcanbeused in
Zone1 andZone2 areas withgases ingroups IIA,IIBand IIC
and temperature ClassificationsofT1, T2, T3 andT4. For
ambient temperaturesover +55ºCthegasgroupsare limited to
IIAand IIB.They canalso beused inZone21 and Zone 22
areas for combustible dusts and have anIP rating of IP67 and
asurfacetemperaturerating ofT100ºCup to+55ºCand
T115ºC over +55ºC.

6) SontelLocation and Mounting
The locationof the Sontelsshould be madewithdue regardto
the area over whichthewarningsignalmustbeaudible. And
they shouldonlybe fixedto services that cancarry the weight
of theunit.
The Sontels shouldbesecurely boltedtoasuitablesurface
usingthe7mmdiameter boltholesinthe stainlesssteelU
shapedmounting bracket(see figure1). The anglecan then be
adjusted in the directionthat the sound is primarily required to
cover. Thiscan beachieved by looseningthetwolarge bracket
screwsin the side of theunit, which allow adjustment in steps
of18°.Oncompletion of the installation thetwo largebracket
adjustment screws onthe sideof theunit must befully
tightenedto ensurethat theunit cannotmovein service.
7) AccesstotheFlameproofEnclosure
Inorder to connect theelectrical supply cableandthe
telephonelinecabletothe Sontel it isnecessarytoremovethe
flameproof covertogain accessto theflameproofchamber.
Toachieve this remove thefourM6 hexagon sockethead
screws(see figure2)and withdraw theflameproofcovertaking
extremecarenotto damagetheflameproof jointsinthe
process.
Notethefour M6screwsareClass A4-80stainless steel
and onlyscrewsof thiscategorycanbeusedon these
Sontels. Itis thereforeimportant that thesescrews and their
springwashersarekept ina 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 castingensurethat itis square
withthe flameproof chamber castingbefore inserting. Carefully
push thecoverin placeallowing timefor theair to be expelled.
Only afterthecover is fullyin placeshould the fourM6
StainlessSteelA4-80 coverboltsand theirspringwasherbe
insertedand tighteneddown. If the coverjamswhile it isbeing
inserted, carefully remove it andtry again.Never use thecover
boltsto force the cover intoposition.
8) PowerSupplySelection
Itis important that asuitable powersupplyisused torunthe
Sontels.
The followingtableshowstheinputcurrent taken by the
various units:-

9) CableSelection
Whenselecting the cable size consideration mustbegivento
the inputcurrentthateach unit draws(seetable above), and
the length ofthe cableruns.
SAFETY WARNING: If the high outputBExDTS110D units are
used athighambienttemperatures,i.e. over+40ºC, then the
cable entrytemperature mayexceed +70ºCand therefore
suitable heat resistingcablesmustbeused, witharated
service temperatureofat least 110ºC.
10) Earthing
The Sontelunits mustbeconnectedtoagood quality earth.
The unitsareprovidedwithinternal and externalearthing
terminalswhichare bothlocatedonthe terminalchamber
sectionoftheunit (seefigures 2and3).
Whenusingtheinternal earth terminalensure thatthe
stainlesssteelM4flat washer isbetweentheincoming earth
wireand the enclosure.
Whenusingtheinternal earth terminalensure thatthe
stainlesssteelM4flat washer isbetweentheincoming earth
wireand the enclosure.
When using theexternal earthterminal a cablecrimp lugmust
be used. Thecablelugshould be locatedbetween thetwoM5
stainlesssteelflat washers. TheM5stainlesssteel spring
washermust be fixed betweenthe outer flatwasher andthe
M5 stainless steel nut toensurethatthe cablelugissecured
againstlooseningand twisting.
The internalearthbondingwireensures that agoodquality
earth is maintained betweentheflameproofchambercasting
and the flameproofcovercasting.
11) CableGlands
The BExDTS110DSontelshave dual cableglandentries
whichhave an M20x1.5asstandard.Onlycable glands
approvedfor Ex‘d’applicationscan beused,which mustbe
suitable forthetype ofcablebeingusedand alsomeetthe
requirementsofthe Ex‘d’flameproof installationstandard
EN60079-14:2008/ 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 toEN 60529.
SAFETY WARNING: IftheBExDTS110D Sontelsareusedat
high ambienttemperatures,i.e.over+40ºC,thenthecable
entry temperaturemay exceed+70ºCand thereforesuitable
heatresisting cable glands mustbe used,with arated service
temperature of at least 110ºC.
12) CableConnections
The cableconnectionsaremadeinto theterminal blockson
the Sontelpcbassemblylocated in theflameproof enclosure.
Seesection7ofthismanualfor access totheflameproof
enclosure.Theprintedcircuitboardhastwoterminal blocks;
one for thepowersupply inputvoltageand onefor the
telephone signalinputcable(seefigures 4and 5). The power
input cableshouldenterthe enclosurevia oneofthe M20
cable entries and be connected to thesupply terminals (L and
N) AC units (+ve and –ve) DCunitsandthetelephonesignal
cable should entertheenclosure via theotherM20entryand
be connectedtothetelephone terminal.
A singlewire withacross sectionalarea ofup to 4mm² can be
connectedtoeachterminal way. Whenconnecting wires to the
terminalsgreat care should betakento dressthewire so that
whenthecoverisinsertedintothechamberthewires donot
exert excesspressureonthe terminalblocks. Thisis
particularlyimportantwhenusingcableswithlarge cross
sectional areassuchas2.5mm² andabove.

13) ToneSelection
The BExDTS110D Sontels have 32 differenttones that can be
selected bytheDIPswitchesonthe sounderpcb(seefigures
4and5). Thetone tableon page four showstheswitch
positionsforthe32tones.
14) PulseToneOperation
The BExDTS110DSontelhastwo modes ofoperation
continuoustone operationandpulsedtoneoperation. To
selectcontinuoustoneoperationthepulse toneheader pins
should notbeshorted(seefigures 4 and5). Inthis modethe
output tone will beas per the tone table.To select pulse tone
operation thepulsetone headerpinsshouldbeshorted (see
figures4and5).Inthismodeof operationthe selected tone
pattern willpulseon andofffollowingthetelephone input
signal. Note if pulsedtone operationis selected it is advisable
nottoselectanyof theintermittenttones, such astone11.
15) VolumeControl
The BExDTS110DSontel hasavolumecontrol toadjustthe
output level. To setthe requiredoutputlevel, adjust the
potentiometeronthe sontelpcb (see figure4).Formaximum
output level the potentiometershouldbeset tothe fully
clockwise position.
