E2S GNExS2 Instruction Manual

1) Introduction
The GNExS2 and GNExS1 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. Sixty-
four different stage alarm sounds can be selected by internal
switches to independently set the first stage and second
stage, the third and fourth stages are externally changed (see
tone table on Page 5/6). The GNExS2 unit produces output
levels in the 117dB (A) range and the GNExS1 unit produces
output levels in the 110dB (A) range.
The sounders are Group II, EPL (equipment protection level)
Gb. Dependant on unit type and ambient temperature the
equipment is certified 'Ex db IIC Gb' and as such may be
used in Zones 1 and 2 with flammable gases and vapours
with apparatus groups IIA, IIB & IIC and temperature
Classifications of T1, T2, T3 and T4 dependant on ambient
temperature, see marking codes in section 2.
The equipment is also certified 'Ex db IIB Gb' and as such
may be used in Zones 1 and 2 with flammable gases and
vapours with apparatus groups IIA & IIB and temperature
Classifications of T1, T2, T3, T4, T5 and T6 dependant on
ambient temperature, see marking codes in section 2.

3) Type Approval Standards
The sounders have an EC Type Examination and IECEx
certificates issued by KEMA and have been approved to the
following standards:-
EN60079-0:2018 EN IEC60079-0:2018
EN60079-1:2014 A/C:2018 EN 60079-1:2014 ed. 7
4) Special Conditions for Safe Use
4.1) Installation
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
atmospheres (other than mining applications or explosive
processing and manufacture):-
EN60079-14:2008
IEC60079-14:2007 (Ed4)
EN60079-10-1:2009
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.
4.2) Specific Conditions
Flameproof joints shall not be repaired or modified in any way
(See figures 1 & 2 for location of flameproof joints).
The enclosure is non-conducting and under certain extreme
conditions may generate an ignition capable level of
electrostatic charge. The user shall ensure that the
equipment is not installed in a location where it may be
subjected to extreme conditions (such as high-pressure
steam) which might cause a build-up of electrostatic charge
on non-conducting surfaces.
