INSTRUCTION MANUAL (ATEX / IECEx)
BExDCS110-05D
Flameproof Combined Sounder / Beacon
For use in Flammable Gas and Dust Atmospheres
1) Introduction
The BExDCS110-05D is flameproof combined sounder /
beacon which is certified to meet the requirements of the
ATEX directive 94/9/EC and the IECEx scheme. The sounder
section produces loud audio warning signals and the beacon
section produces a synchronised visual warning signal. The
unit can be used in hazardous areas where potentially
flammable gas and dust 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 and the beacon has a flash energy of 5
joules. 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 based on a Ta max. of 70ºC (T100ºC at +55ºC).
2) Marking

Installation Requirements
The unit must be installed in accordance with the latest
issues of the relevant parts of the EN60079 specifications or
the equivalent IEC specifications – Selection, Installation and
maintenance of electrical apparatus for use in potentially
explosive atmospheres (other than mining applications or
explosive processing and manufacture):-

The installation of the unit 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)
Zones, Gas Group, Category, IP Rating and
Temperature Classification
The BExDCS110-05D unit has been certified Ex d IIB T4 for
Ta –50°C to +70ºC for gas and Ex tD A21 IP6X T115ºC
based on max. Ta of +70ºC for dust. This means that the
units can be installed in locations with the following
conditions:-
Area Classification Gas:
Zone 1
Explosive gas air mixture likely to occur in
normal operation.
Zone 2
Explosive gas air mixture not likely to occur,
and if it does, it will only exist for a short time.
