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.

Entries
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
