INSTRUCTION MANUAL (ATEX / IECEx)
BExBGL1D Flameproof LED Beacon
For use in Flammable Gas and Dust Atmospheres
1) Introduction
The BExBGL1D is a flameproof LED beacon which is
certified to meet the ATEX directive 94/9/EC and the IECEx
scheme. The beacon produces visual warning signals and
can be used in hazardous areas where potentially flammable
gas and dust atmospheres may be present. The BExBGL1D
LED beacon has nine different flash patterns including a
steady ON state and can also be remotely switched to a
second and third flash pattern. The beacon 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. It
can also be used in a temperature classification T5, if the
upper ambient temperature is restricted to +40ºC. The unit
can 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 T120ºC or T105ºC if the upper ambient
temperature is restricted to +55ºC and T95ºC if the upper
ambient temperature is restricted to +40ºC.
2) Marking

3) Type Approval Standards
The beacon has EC Type Examination and IECEx certificates
issued by KEMA and have been approved to the following
standards:-
EN60079-0:2006 IEC60079-0:2004 (Ed4)
General Requirements
EN60079-1:2007 IEC60079-1:2007

4) Installation Requirements
The led beacons must be installed in accordance with the
latest issues of the relevant parts of the BS EN 60079
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):-
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, IP Rating and
Temperature Classification
The BExBGL1D beacons have been certified Ex d IIC T4 for
Ta –50ºC to +70ºC and Ex d IIC T5 for Ta –50ºC to +40ºC for
gas and IP67 T120ºC Ta < +70ºC, T105ºC Ta < +55ºC and
T95ºC Ta < +40ºC 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.
Gas Groupings:
Group IIA
Propane
Group IIB
Ethylene
Group IIC
Hydrogen and Acetylene
