1) Introduction
The BExDCS110-L1D is a flameproof combined sounder /
LED beacon which is certified to meet the requirements of the
ATEX directive 94/9/EC and the IECEx Scheme. The
combined unit produces both loud audio warning signals and
visual warning signals that can be used in hazardous areas
where potentially flammable atmospheres may be present.
Thirty-two different first stage audio alarm sounds can be
selected by internal switches, and each one can be externally
changed to a second or third stage alarm sound (see tone
table on Page 5). The sounder produces output levels in the
110dB(A) range. The beacon section has nine different
selectable flash patterns including a steady ON state and can
also be remotely switched to a second and third flash pattern
(see flash pattern table on page 5). The unit can be used in
Zone 1 and Zone 2 areas with gases in groups IIA and IIB
and with Temperature Classifications of T1, T2, T3 and T4
and can also be used in Zone 21 and Zone 22 areas for
combustible dusts and has an IP rating of IP 67 and a surface
temperature rating of T115ºC (T100ºC at +55ºC).

5) Location and Mounting
The location of the unit should be made with due regard to
the area over which both the sounder and beacon warning
signal must be audible and visible. The unit should only be
fixed to services that can carry the weight of the unit.
The unit should be securely bolted to a suitable surface using
the 7mm diameter boltholes in the stainless steel U shaped
mounting bracket (see figure 1). The angle can then be
adjusted in the direction such that its warning signals can be
both heard and seen. This can be achieved by loosening the
two large bracket screws in the side of the unit, which allow
adjustment in steps of 18°. On completion of the installation
the two large bracket adjustment screws on the side of the
unit must be fully tightened to ensure that the unit cannot
move in service.
6) Access to the Flameproof Enclosure
In order to connect the electrical supply cables to the unit it is
necessary to remove the beacon section to gain access to
the flameproof chamber. To achieve this remove the four M6
hexagon socket head screws (see figure 2) and withdraw the
beacon section taking extreme care not to damage the
flameproof joints in the process.
Note the four M6 screws are Class A4-80 stainless steel
and only screws of this category can be used on these
units. It is therefore important that these screws and their
spring washers are kept in a safe place during installation.
On completion of the cable wiring installation the flameproof
joints should be inspected to ensure that they are clean and
that they have not been damaged during installation. Also
check that the earth bonding wire between the two casting
sections is secure and the ‘O’ ring seal is in place. When
replacing the beacon section casting, ensure that it is square
with the sounder section chamber casting before inserting.
Carefully push the beacon section in place allowing time for
the air to be expelled. Only after the beacon section casting 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 beacon section jams while it is being inserted,
carefully remove it and try again. Never use the cover bolts to
force the beacon section casting into position.
In case of repair, contact the manufacturer for information on
the dimensions of the flameproof joints.
7) Power Supply Selection
It is important that a suitable power supply is used to run the
unit. The power supply selected must have the necessary
capacity to provide the input current to all of the units
connected to the system. The sounder and LED beacon
sections can both be wired to the same power supply or to
different power supplies
The following table shows the input current taken by the
sounder section and beacon section of the various units:-
Unit Type Input Sounder Max.
Voltage Current I/P Volts
BExDCS110-L1D 24V DC 265mA 30V
BExDCS110-L1D 12V DC 195mA 15V
BExDCS110-L1D 48V DC 130mA 50V
BExDCS110-L1D 230V AC 56mA 253V
BExDCS110-L1D 115V AC 110mA 126V
Unit Type Input LED Beacon Max.
Voltage Current I/P Volts
BExDCS110-L1D 24V DC 400mA 30V
BExDCS110-L1D 12V DC 760mA 15V

voltage regulator circuit and therefore the input current level
will decrease slightly as the input voltage in increased and
will increase slightly as the input voltage is reduced. The 12V
units do not have a voltage regulator and therefore their input
current will increase when the input voltage is increased.
LED 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 voltages of 12V, 24V and 48V DC the units
have a converter circuit and therefore the input current level
will decrease slightly as the input voltage in increased and
will increase slightly as the input voltage is reduced.
8) Cable Selection
When selecting the cable size consideration must be given to
the input current that each unit draws (see table above), the
number of units 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 units connected to the
line.
SAFETY WARNING: If the unit is used at high ambient
temperatures, i.e. over +40ºC, then the cable entry
temperature may exceed +70ºC and therefore suitable heat
resisting cables must be used, with a rated service
temperature of at least 110ºC.
9) Earthing
Both AC and DC units must be connected to a good quality
earth. The units are provided with internal and external
earthing terminals, which are both, located on the beacon
section of the unit (see figures 2 and 3).
N L
When using the external earth terminal a cable crimp lug
must be used. The cable lug should be located between the
two M5 stainless steel flat washers. The M5 stainless steel
spring washer must be fixed between the outer flat washer
and the M5 stainless steel nut to ensure that the cable lug is
secured against loosening and twisting.
The internal earth bonding wire ensures that a good quality
earth is maintained between the sounder section casting and
the beacon section casting.
10) Cable Glands
The BExDCS110-L1D unit has dual cable gland entries which
have an M20 x 1.5 entry thread as standard. Only cable
glands approved for Ex ‘d’ applications can be used, which
must be suitable for the type of cable being used and also
meet the requirements of the Ex ‘d’ flameproof installation
standard EN60079-14:2008 / IEC60079-14.
SAFETY WARNING: If the unit is used at high ambient
temperatures, i.e. over +40ºC, then the cable entry
temperature may exceed +70ºC and therefore suitable heat
resisting cable glands must be used, with a rated service
temperature of at least 110ºC.
When only one cable entry is used the other one must be
closed with an Ex ‘d’ flameproof blanking plug, which must be
suitably approved for the installation requirements.
For combustible dust applications, the cable entry device and
blanking elements shall be in type of explosion protection
increased safety "e" or flameproof enclosure "d" and shall
have an IP 6X rating according to EN60529:1992.
11) Cable Connections
The combined sounder LED beacon unit BExDCS110-L1D
has separate printed circuit boards in the sounder and LED
beacon sections. The terminals for the sounder 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 4&5 and 6&7). See section 8 of this
manual for access to the enclosure and the wiring diagrams
at the end of this manual.
The sounder and LED 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 diagrams on page 6 of this
manual). 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 LED beacon board
and the two connecting 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.
SOUNDER SECTION CONECTIONS
On the AC units a two-way terminal block is provided for the
live and neutral mains supply wires and a three way terminal
block is provided for linking the second and third stages, (see
figure 7). On the DC units a four way terminal block is
provided for +ve and –ve supply input and second and third
stage modes of operation, (see figure 6).
A single wire with a cross sectional area of up to 4mm² can
be connected to each terminal way or if an input and output
wire is required two 2.5mm² wires can be connected to each
terminal way. When connecting wires to the terminals great
care should be taken to dress the wire so that when the
beacon section 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 and above. If the sounder is
wired to the same power supply as the beacon always use
the flexible interconnecting wires provided.

LED BEACON SECTION CONNECTIONS
The cable supply connections are made into the terminal
blocks on the electronic pcb assembly located in the
flameproof LED beacon section enclosure, see section 8 of
this manual for access to the flameproof enclosure. The AC
unit has two live terminals and two neutral terminals for the
input and output supply wiring and the DC unit has two +ve
terminals and two -ve terminals for the input and output
supply wiring. Both units have S2 and S3 terminals to
remotely change the flash pattern, see section 16 of this
manual.
Wires having a cross sectional area of up to 4mm² can be
connected to each terminal way. When connecting wires to
the terminals great care should be taken to dress the wires so
that 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 and above.

12) Tone Selection and 2nd and 3rd Stage Alarms
The BExCS110-L1D sounder section has 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 sounder pcb for both DC and AC units. The tone table on
page five 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).
The operation of the second and third stages is different for
DC and AC units.
DC Units Second and Third Stage Tone Selection
The BExCS110-L1D DC sounder section has the facility to
use either +ve or –ve switching to change the tone to the
second and third stages. 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. To change to the second
stage tone, connect either a -ve or +ve supply line to terminal
S2, depending on which switching mode is being used while
maintaining the dc supply to the +ve and –ve terminals.
Similarly for the third stage tone, connect a -ve or +ve supply
line to terminal S3. The supply to the S3 terminal will
automatically override a supply to the S2 terminal.
AC Units Second and Third Stage Tone Selection
To select the second and third stage tones on the
BExDCS110-L1D AC sounder section, the Common (C)
terminal on the three way terminal block on the pcb is
connected to the S2 terminal for the second stage tone and
the S3 terminal for the third stage tone.
Volume Control
The BExDCS110-L1D sounder section, with the exception of
12V DC units, has a volume control to adjust the output level.
To set the required output level, adjust the potentiometer on

the pcb. For maximum output level the potentiometer should
be set to the fully clockwise position.
13) Flash Pattern Selection and 2nd & 3rd Stages
The BExDCS110-L1D LED beacons have 9 different flash
patterns including one ON state that can be selected for the
first stage. They can then be remotely switched to second
and third stage flash patterns. The flash patterns are selected
by pin headers on the pcb for both DC and AC units. The
table on page five shows the pin header positions for the nine
flash patterns and which patterns are available for the second
and third stages. To operate the led beacon 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).
The operation of the second and third stages is different for
DC and AC units.
DC Units Second and Third Stage Selection
To change to the second stage flash pattern, simply connect
a -ve supply line to terminal S2, while maintaining the dc
supply to the +ve and –ve terminals. Similarly for the third
stage flash pattern, connect a -ve supply line to terminal S3.
The supply line to the S3 terminal will automatically override
a supply to the S2 terminal.
AC Units Second and Third Stage Selection
To select the second and third stage flash patterns on the
BExDCS110-L1D AC beacons the Common (C) terminal on
the three way terminal block on the pcb is connected to the
S2 terminal for the second stage tone and the S3 terminal for
the third stage tone.

14) Line Monitoring (DC Units)
On BExDCS110-L1D DC units, dc reverse line monitoring
can be used if required. All DC units have a blocking diode
fitted in their supply input lines on both the sounder section
and the LED beacon section. 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 3k3 ohms and a
minimum wattage of 0.5 watts or a minimum resistance value
of 500 ohms and a min. wattage of 2 watts. If the sounder
and beacon sections are wired to separate power supplies,
then an end of line monitoring component can be used in
each section.
