BExTBG05D Flameproof Flashtel
For use in Flammable Gas and Dust
Atmospheres
1) Introduction
The BExTBG05D is a flameproof Flashtel which is certified to
meet the requirements of the ATEX directive 94/9/EC and
IECEx scheme. The Flashtel produces a visual warning
signal when triggered by a telephone ringing signal and can
be used in hazardous areas where potentially flammable gas
and dust atmospheres may be present. The BExTBG05D has
a flash energy level of 5 joules and 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 andT4. The unit
can also be used in a temperature classification T5, if the
upper ambient temperature is restricted to +55ºC and T6 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 T110ºC or T95ºC if the upper ambient
temperature is restricted to +55ºC and T85ºC if the upper
ambient temperature is restricted to +40ºC.
2) Marking

4)
Installation Requirements
The Flashtel must be installed in accordance with the latest
issues of the relevant parts of the EN60079 standards or the
equivalent IEC 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
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 BExTBG05D beacons have been certified Ex d IIC T4 for
Ta –50ºC to +70ºC, Ex d IIC T5 for Ta –50ºC to +55ºC and
Ex d IIC T6 for Ta –50ºC to +40ºC for gas and IP67 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.
