European Safety Systems BE S120D Serie Manual De Instrucciones

1) Introduction
The BExS120D and BExS110D are flameproof sounders
which are certified to meet the requirements of the ATEX
directive 94/9/EC and the IECEx scheme. The sounders
produce loud warning signals and can be used in hazardous
areas where potentially flammable atmospheres may be
present. Thirty-two different first stage 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 4). The BExS120D unit produces output levels
in the 117dB(A) range and the BExS110D unit produces
output levels in the 110dB(A) range. Both sounders can be
used in Zone 1 and Zone 2 areas with gases in groups IIA,
IIB and IIC and temperature Classifications of T1, T2, T3 and
T4. For ambient temperatures over +55ºC the gas groups are
limited to IIA and IIB.
2) Marking
All units have a rating label, which carries the following
important information:-
BExS120D or BExS110D
Unit Type No.
Input Voltage: DC Units 12V or 24V or 48V
AC Units 230V or 110V or 115V

Installation Requirements
The sounders must be installed in accordance with the latest
issues of the relevant parts of the EN 60079 and IEC60079
standards – Selection, Installation and maintenance of
electrical apparatus for
atmospheres (other than mining applications or explosive
processing and manufacture):-
EN60079-14:2008 Electrical Installations in Hazardous
IEC60079-14:2007 (Ed4) Areas (other than mines)
EN60079-10:2003 Classification of Hazardous Areas
IEC60079-10:2008 (Ed1)
The installation of the units 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 and Temperature
Classification
The BExS120D and BExS110D sounders have been certified
Ex d IIC T4 for Ta –50°C to +55ºC and Ex d IIB T4 for Ta –
50°C to +70ºC. This means that the units can be installed in
locations with the following conditions:-
Area Classification:
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.
Gas Groupings:
Group IIA
Group IIB
Group IIC (Up to +55ºC only)
Equipment Category: 2G
Temperature Classification:
T1 400
T2 300
T3 200
T4 135
Ambient Temperature Range:
-50°C to +55°C Gas Groups IIA, IIB and IIC
-50°C to +70°C Gas Group IIA and IIB
6)
Sounder Location and Mounting
The location of the sounders should be made with due regard
to the area over which the warning signal must be audible.
The sounders should only be fixed to services that can carry
the weight of the unit.
