E2S BExDTS110D Instruction Manual

1) Introduction
The BExDTS110D is a flameproof Sontel telephone sounder
which is certified to meet the requirements of the ATEX
directive 94/9/EC and IECEx scheme. The Sontel produces a
loud audible 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. Thirty-
two different sounds can be selected by internal switches (see
tone table on Page 4).
output levels in the 110dB(A) range. The unit 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. They can also be used in Zone 21 and Zone 22
areas for combustible dusts and have an IP rating of IP 67 and
a surface temperature rating of T100ºC up to +55ºC and
T115ºC over +55ºC.

Installation Requirements
The Sontels must be installed in accordance with the latest
issues of the relevant parts of the EN 60079 standards or the
equivalent IEC standards –
maintenance of electrical apparatus for use in potentially
explosive atmospheres (other than mining applications or
explosive processing and manufacture):-
EN60079-14:2008
IEC60079-14:2007 (Ed4)
EN60079-10:2003
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.

Zones, Gas Group, Category, IP Rating and
Temperature Classification
The BExDTS110D Sontels have been certified Ex d IIC T4 for
Ta –50°C to +55ºC and Ex d IIB T4 for Ta –50°C to +70ºC for
gas and Ex tD A21 IP67 T115ºC based on max. Ta of +70ºC
for dust. This means that the units can be installed in locations
with the following conditions:-
