1)
Introduction
The GNExCP6B-PB/ GNExCP6D-PB/ GNExCP6E-
PB is a push button manual call point which is
certified to the European and International Gas and
Dust standards. The unit meets the requirements of
the ATEX directive 2014/34/EU, IECEx and UKEX
schemes.
The call point can be used in hazardous areas
where potentially flammable gas and dust
atmospheres may be present.
All units have up to two of the following series and/
or EOL devices:
Monitoring resistors per module: -
GNExCP6B-PB - 2.0W Max
GNExCP6D-PB - 1.0W Max
GNExCP6E-PB - 1.75W Max
Monitoring diode
Monitoring Zener diode
GNExCP6B-PB units may also incorporate an LED
indicator in addition to the two series and/ or EOL
devices allowed.
The units are Group II, EPL (equipment protection
level) Gb. The equipment is certified ‘Ex db eb mb
IIC T4 Gb’ and as such may be used in Zones 1
and 2 with flammable gases and vapours with gas
groups IIA, IIB & IIC and temperature classes T1,
T2, T3 and T4.
These units are also Group III, EPL Db. The
equipment is certified:
‘Ex tb IIIC T80ºC Db’ (GNExCP6B-PB),
‘Ex tb IIIC T80ºC Db’ (GNExCP6D-PB),
‘Ex tb IIIC T75ºC Db’ (GNExCP6E-PB)
and as such may be used in Zones 21 and 22 for
combustible dusts groups IIIA, IIIB & IIIC.

Installation Requirements
Installation of this equipment shall only be carried
out by suitably trained personnel in accordance
with the applicable code of practice e.g.
IEC 60079-14/EN 60079-14
Repair of this equipment shall only be carried out
by the manufacturer or in accordance with the
applicable code of practice e.g. IEC 60079-19/EN
60079-19.
Refer to certificates SIRA 09ATEX3286X, IECEx
SIR 09.0121X and CSAE 21UKEX3556X for
special conditions of safe use.
The certification of this equipment relies on the
following materials used in its construction:
Enclosure:
GRP - Glass Reinforced Polyester
Through enclosure mechanism: Plastic Nylon Zytel
Injection Moulded
Sealing of enclosure and mechanism: O-ring
Acrylonitrile-Butadiene Rubber.
Potting Compound of resistors where used: Epoxy
Resin
If the equipment is likely to come into contact with
aggressive substances, then it is the responsibility
of the user to take suitable precautions that prevent
it from being adversely affected, thus ensuring that
the type of protection is not compromised.
“Aggressive substances” - e.g. acidic liquids, gases
or solvents that may affect polymeric materials.
“Suitable precautions” - e.g. regular checks as part
of routine inspections or establishing from the
material’s data sheet that it is resistant to specific
chemicals.
Under extreme conditions the unit may generate an
ignition-capable level of electrostatic charges. The
unit must not be installed in a location where it may
be subjected to external conditions (such as high-
pressure steam) which may cause a build-up of
electrostatic charges on non-conducting surfaces.
Cleaning of the unit must only be carried out with a
damp cloth.
5)
Call Point Location and Mounting
The location of the call point should enable ease of
access for operation and testing. The unit should
be mounted using the 4 off fixing holes which will
accept up to M5 sized fixings.

To gain access to the mounting holes in the base
the
front
cover
must
be
removed.
