BExBG15E and BExBG10E
Flameproof / Increased Safety Xenon Beacons
For use in Flammable Gas and Dust Atmospheres
1) Introduction
The BExBG15E and BExBG10E beacons are flameproof
beacons which are certified to meet the requirements of the
ATEX directive 94/9/EC and the IECEx scheme. The
beacons produce synchronised visual warning signals and
can be used in hazardous areas where potentially flammable
gas and dust atmospheres may be present. The BExBG15E
has a flash energy level of 15 joules and the BExBG10E has
a flash energy level of 10 joules. The beacons 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.
The beacons can also be used in the temperature
classification T5, if the upper ambient temperature is
restricted to +40ºC.
The units can be used in Zone 21 and
Zone 22 areas for combustible dusts and have an IP rating of
IP 66 and a surface temperature of T125ºC based on max Ta
of +70°C.
2) Marking
All units have a rating label, which carries the following
important information:-
Unit Type No.

Installation Requirements
The beacons must be installed in accordance with the latest
issues of the relevant parts of the EN60079 and IEC60079
standards – 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

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 BExBG15D and BExBG10D beacons have been certified
Ex de IIC T4 for Ta –50ºC to +70ºC and Ex de IIC T5 for Ta –
50ºC to +40ºC for gas and Ex tD A21 IP66 T125ºC based on
max. +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.
Gas Groupings:
Group IIA
