EN 60079-31:2014 / IEC60079-31:2013 (Ed 2):
Explosive Atmospheres - Equipment dust ignition protection
by enclosure "t"
4) Installation Requirements
The combined sounder beacon must only be installed by
suitably qualified personnel in accordance with the latest
issues of the relevant standards:
EN60079-14 / IEC60079-14: Explosive atmospheres -
Electrical installations design, selection and erection
EN60079-10-1 / IEC60079-10-1: Explosive atmospheres -
Classification of areas. Explosive gas atmospheres
EN60079-10-2 / IEC60079-10-2: Explosive atmospheres –
Classification of areas. Explosive dust atmospheres
The installation of the combined sounder beacon must also
be in accordance with any local codes that may apply and
should only be carried out by a competent electrical engineer
who has the necessary training.
5) Special Conditions of Use
Repair of the flamepath / flameproof joints is not permitted.
The enclosure is non-conducting and may generate an
ignition-capable level of electrostatic charges under certain
extreme conditions (such as high-pressure steam). The user
should ensure that the equipment is not installed in a location
where it may be subjected to external conditions that might
cause a build-up of electrostatic charges on non-conducting
surfaces.
Additionally, cleaning of the equipment should be done only
with a damp cloth.
6) Location and Mounting
The location of the combined sounder beacon should be
made with due regard to the area over which the warning
signal must be visible. They should only be fixed to services
that can carry the weight of the unit.
The BEx combined sounder beacon should be secured to
any flat surface using at least two of the three 7mm fixing
holes on the stainless steel U shaped mounting bracket. See
Figure 1. The required angle can be achieved by loosening
the two large bracket screws in the side of the unit, which
allow adjustment of the combined sounder beacon in steps of
18°. On completion of the installation then two large bracket
adjustment screws on the side of the unit must be fully
tightened to ensure that the unit cannot move in service.

Fig. 1b Fixing Location for Combined Radial
7) Access to the Flameproof Enclosure
To access the Ex d chamber, remove the four M6 hexagon
socket head screws and withdraw the flameproof cover taking
extreme care not to damage the flameproof joints in the
process. M6 cover screws are Class A4-80 stainless steel
and only screws of this category can be used for the
enclosure.
Fig. 2 Accessing the Explosion proof Enclosure.
On completion of the installation, the flameproof joints should
be inspected to ensure that they are clean and that they have
not been damaged during installation.
Check that the earth bonding wire between the two castings
is secure and the ‘O’ ring seal is in place. When replacing the
flameproof cover, casting ensure that it is square with the
flameproof chamber casting before inserting. Ensure correct
orientation of Beacon Housing onto Sounder housing when
closing unit. Please note that due to the tight spacing
internally the Beacon housing can only be closed in one
orientation relative to the Sounder housing, otherwise PCB
boards may become damaged.
The M20 entries on the Beacon housing must be aligned with
the product labels on the side of the Sounder housing (both

M20 entries and labels on the same side). Carefully push the
cover in place allowing time for the air to be expelled. Only
after the cover is fully in place should the four M6 Stainless
Steel A4-80 cover bolts and their spring washer be inserted
and tightened down. If the cover jams while it is being
inserted, carefully remove it and try again. Never use the
cover bolts to force the cover into position.
8) Power Supply Selection
It is important that a suitable power supply is used to run the
equipment. The power supply selected must have the
necessary capacity to provide the input current to all of the
units.
The following table shows the input current taken by the
various combined sounder beacons and shows the maximum
voltage at which the combined sounder beacons can be
operated:
Sounder Section
The input current to the sounder section will vary according to
the voltage input level and the frequency of the tone selected.
The current levels shown above are for the 440Hz
Continuous tone @ nominal input voltage.
Beacon Section
The input current to the beacon section will vary according to
the voltage input level. The current levels shown above are
for nominal input voltage.
9) Selection of Cable. Cable Glands, Blanking
Elements & Adapters
When selecting the cable size, consideration must be given
to the input current that each unit draws (see table above),
the number of combined sounder beacons on the line and the
length of the cable runs. The cable size selected must have
the necessary capacity to provide the input current to all of
the combined sounder beacons connected to the line.
For ambient temperatures, over +40ºC the cable entry
temperature may exceed +70ºC and therefore suitable heat
resisting cables and cable glands must be used, with a rated
service temperature of at least 110ºC
The dual cable gland entries have an M20 x 1.5 entry thread.
To maintain the ingress protection rating and mode of
protection, the cable entries must be fitted with suitably rated
ATEX / IECEx certified cable glands and/or suitably rated
ATEX / IECEx certified blanking devices during installation
according to EN / IEC60079-14.
If a high IP (Ingress Protection) rating is required, then a
suitable sealing washer must be fitted under the cable glands
or blanking plugs.
For use in explosive dust atmospheres, a minimum ingress
protection rating of IP6X must be maintained.
The BEx combined sounder beacon range can be supplied
with the following types of adapters:
M20 to ½” NPT
M20 to ¾” NPT
M20 to M25
It is important to note that stopping plugs cannot be fitted
onto adapters, only directly onto the M20 entries.
Any other adapters used must be suitably rated and ATEX /
IECEx certified adapters.
10) Earthing
Both AC and DC combined sounder beacon units must be
connected to an earth. The units are provided with internal
and external earth terminals which are both located on the
terminal chamber section of the unit.
Fig. 3 Internal View of Cover
When using the internal earth terminal ensure that the
stainless steel M4 flat washer is between the incoming earth
wire and the enclosure.
Internal earthing connections should be made to the Internal
Earth terminal in the base of the housing using a ring crimp
terminal to secure the earth conductor under the earth clamp.
The earth conductor should be at least equal in size and
rating to the incoming power conductors.
External earthing connections should be made to the M5
earth stud, using a ring crimp terminal to secure the earth
conductor to the earth stud. The external earth conductor
should be at least 4mm² in size.
11) Cable Connections
The combined sounder beacon unit BExCTS110-05D has
separate printed circuit boards in the sounder and beacon
sections. The terminals for the incoming power supply and
telephone signal are on the printed circuit board in the
sounder section and the terminals for the beacon are on the
printed circuit board in the beacon section (see figures 5a,
5b, 7a and 7b). See section 7 of this manual for access to the
enclosure. See section 12 and 13 for AC and DC wiring
diagrams respectively.
Wires having a cross sectional area between 0.5 mm² to
2.5mm² can be connected to each terminal way. If an input
and output wire is required, the 2-off Live/Neutral or +/-
terminals can be used. If fitting 2-off wires to one terminal

way, the sum of the 2-off wires must be a maximum cross
sectional area of 2.5mm². Strip wires to 8mm. Wires may also
be fitted using ferrules. Terminal screws need to be tightened
down with a tightening torque of 0.45 Nm / 5 Lb-in. When
connecting wires to the terminals great care should be taken
to dress the wires so that when the cover is inserted into the
chamber the wires do not exert excess pressure on the
terminal blocks. This is particularly important when using
cables with large cross sectional areas such as 2.5mm².
12) AC Wiring
Four connections must be made to the BExCTS110-05D AC
unit. A power supply input cable should enter the enclosure
via one of the M20 entries and a telephone signal cable
should enter through the other M20 entry.
Connect the power input (L) to the telephone board (L/+)
terminal in the sounder section & power input (N) to the
beacon board (N) terminal in the beacon section.
Connect the telephone signal input to (TB1) on the telephone
board in the sounder section. See Figure 4

14) Settings
14.1 Tone Selection
The sounders have 32 different tones that can be selected for
the first stage alarm. The tones are selected by operation of a
DIP switch on the pcb for both DC and AC units. The tone
table on page eight shows the switch positions for the 32
tones. To operate the sounder on stage one simply connect
the supply voltage to the normal supply terminals (+ve and
-ve for DC units, L and N for AC units).
14.2 Telephone Setting DIP & Continuous
or Pulse Sounder Beacon Operation
The BExCTS110-05D combined sounder / beacon has a
number of modes of operation. The sounder and beacon can
be set individually to either run continuously or pulsed at the
cadence of the ringing tone.
This is set by setting the DIP switches on the Telephone pcb
(see figures 5a & 7a).
The Telephone Selection Table on page seven shows the
switch positions 1 - 4 for the country setting and switch 5 for
the beacon continuous or pulse mode and switch 6 for the
sounder continuous or pulse mode. When making any
changes to the country selection, the unit needs to be
de-energised for a minimum of 2 minutes for the changes
to take effect.
When pulse mode of operation is selected the tone, pattern
will pulse on and off following the telephone input signal.
Note if pulsed tone operation is selected it is advisable not to
select any of the intermittent tones, such as tone 11.
The beacon will flash at the ringing cadence if pulse is
selected.
14.3 Volume Control
The output level of the BEx sounder can be set by adjusting
the volume control potentiometer (see Fig 8) with the
exception of 12V DC units. For maximum output, set the
potentiometer fully clockwise.
