5. Special Conditions for Safe 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. Product Mounting and Access
The location of the unit 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
1a.1b. The required angle can be achieved by loosening the
two large bracket screws in the side of the unit, which allow
adjustment of the sounder 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. 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.
Warning – High voltage may be present,
risk of electric shock. DO NOT open when
energised, disconnect power before
opening.
Warning – Hot surfaces. External surfaces
and internal components may be hot after
operation, take care when handling the
equipment.

8. 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 sounders 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 sounders
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 or UKEx certified cable glands and/or suitably
rated ATEX / IECEx or UKEx 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 or UKEx certified adapters.
9. Earthing
Both AC and DC sounder 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. Tighten M4 Earth screw to
1Nm.
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. Tighten the Earth nut to 3Nm. Please firmly
tighten the external grounding terminal so that the stud does
not become loose and lay the ground wire so that it is not
caught by twisting and sagging.
10. Cable Connections
Electrical connections are to be made into the terminal blocks
on the PCBA located in the flameproof enclosure. See section
7 of this manual for access to the flameproof enclosure.
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.

Fig. 5b Beacon DC Terminals
12.1 Stage Switching Polarity (DC Units Only)
The BExS110D DC sounders have the facility to use either +ve
or –ve switching to change the tone to the second and third
stages. Negative switching is the default setting. For –ve
switching connect the two headers on the pcb to the left-hand
(marked –ve) and centre pins. For +ve switching connect the
headers to the right hand (marked +ve) and the centre pins.
(Refer to Fig. 6)
Fig. 6 Stage Switching Polarity
12.2 Line Monitoring
On BExS110D DC units, dc reverse line monitoring can be
used if required. All DC sounders have a blocking diode fitted
in their supply input lines. An end of line monitoring diode or
an end of line monitoring resistor can be connected across the
+ve and –ve terminals. If an end of line resistor is used it must
have a minimum resistance value of 3k3Ω and a minimum
power rating of 0.5 watts or a minimum resistance value of
500Ω and a minimum power rating of 2 watts.
The resistor must be connected directly across the +ve and -
ve terminals as shown in the following drawing. The resistor
leads should be kept as short as possible.
Fig. 7 End of Line Resistor Placement
13. Wiring the combined sounder/beacon for
simultaneous operation
The sounder and beacon sections can be wired to the same
input supply so that they operate simultaneously or they can
be wired to separate input supplies so they can be operated
independently (see wiring diagrams D210-06-601 & D210-06-
605).
If the sounder and beacon sections are connected to the same
input supply. The incoming cables should be connected to the
input terminals on the beacon board and the two link wires,
that are supplied with the unit, should be used to link the supply
from the interconnecting terminals on the beacon board down
to the supply terminals on the sounder board.

14. Settings
14.1 Tone Settings
The sounders have 32 different tones that can be selected for
the first stage alarm. The sounders can then be switched to
sound second and third stage alarm tones. The tones are
selected by operation of a DIP switch on the pcb for both DC
and AC units. The tone table D210-95-001-IS shows the switch
positions for the 32 tones and which tones are available for the
second and third stages. 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).
