3) Type Approval Standards
The sounder carries an EC Type Examination Certificate and
IECEx Certificate of Conformity, and have been certified to
comply with the following standards:
EN60079-0:2012+A11:2013 / IEC60079-0:2011 (Ed 6):
Explosive Atmospheres - Equipment. General requirements
EN60079-1:2007 / IEC60079-1:2007 (Ed 6):
Explosive Atmospheres - Equipment protection by flameproof
enclosures "d"
EN 60079-31:2014 / IEC60079-31:2013 (Ed 2):
Explosive Atmospheres - Equipment dust ignition protection
by enclosure "t"
4) Installation Requirements
The sounder 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 sounder 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 sounder 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 sounder should be secured to any flat surface using
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 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. 1 Fixing Location for Sounder 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 – Hot surfaces. External surfaces
and internal components may be hot after
operation, take care when handling the
equipment.
Warning – High voltage may be present,
risk of electric shock. DO NOT open when
energised, disconnect power before
opening.

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 sounders and shows the maximum voltage at which
the sounders can be operated:
The input current 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.
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 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 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 sounder 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 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.
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
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.

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. 7)
Fig. 7 Stage Switching Polarity
13.4 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 3k3Ωand a
minimum power rating of 0.5 watts or a minimum resistance
value of 500Ωand 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.

14.1 Tone Selection
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 on page seven 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).
14.2 Volume Control
The output level of the BEx sounder can be set by adjusting
the volume control potentiometer (see Fig 9). For maximum
