GNExCP6A-BG
Manual Call Point – Break Glass
For use in Flammable Gas and
Combustible Dust Atmospheres.
1) Introduction
The GNExCP6A-BG is a break glass 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 no monitoring resistors, diodes or
zener diodes and are not fitted with an LED
indicator.
The units are Group II, EPL (equipment protection
level) Gb. The equipment is certified ‘Ex db eb IIC
T6 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 classes T1,
T2, T3, T4, T5 and T6.
These units are also Group III, EPL Db. The
equipment is certified ‘Ex tb IIIC T75ºC Db’ and as
such may be used in Zones 21 and 22 for
combustible dusts groups IIIA, IIIB & IIIC.

3) Type Approval Standards
The call point has an EC Type examination
certificate issued by SIRA and have been approved
to the following standards:-
EN60079-0:2018 / IEC60079-0:2017
EN60079-1:2014 / IEC60079-1:2014
EN60079-7:2015 / IEC60079-7:2017
EN60079-18:2015 / IEC60079-18:2014
EN60079-31:2014 / IEC60079-31:2013
The equipment is certified for use in ambient
temperatures in the range -40oC to +70oC and shall
not be used outside this range.
4) 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
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 M4 sized fixings.
View of base unit showing fixing centres (in mm).
To gain access to the mounting holes in the base
the front cover must be removed.
This is achieved by removing the 4 off M4 cap
head bolts holding on the cover.
Once the screws are removed the cover will hang
down out of the way to gain access to the Ex e
terminal block, the internal earth terminal and
mounting hole recesses.

6) Earthing
The unit has an internal earth terminal.
It is recommended that a cable crimp lug is used
on the earth wires.
The internal earth wire is placed under a earth
clamp which will stop the cable twisting. This is
secured by an M4 screw and spring washer.
Internal Earth Ex e terminal block
terminal
Note: Depending on options chosen an 8-Way DIN
Rail or 6-Way terminal block may be selected.
7) Cable connections
There are 3 off cable entries for M20x1.5 Ex e
approved cable glands or stopping plugs with a
minimum ingress protection of IP66.
The unit can be wired in a number of different ways
depending whether normally open or normally
closed contacts are required. See wiring schematic
D154-06-001 for wiring options.
When wiring to Increased Safety terminal
enclosures, you are only permitted to connect one
wire into each way on the terminal block, unless a
pair of wires are crimped into a suitable ferrule. For
the six-way terminal block wire sizes allowable are
0.5mm² to 4.0mm². For the 8-way DIN rail wire
sizes allowable are 0.5mm² to 2.5mm²
Leads connected to the terminals shall be insulated
for the appropriate voltage and this insulation shall
extend to within 1mm of the metal of the terminal
throat. They shall only be installed and wired with
cable in an ambient temperature of -10°C to +80°C
All terminal screws, used or unused, shall be
tightened down to between 0.5 Nm and 0.7 Nm.
8) Testing unit operation
The break glass unit can be tested without the
need to break/replace the frangible glass element.
A test key is used to mechanically drop the glass
down activating the switch.
The test key is inserted in the test cam and rotated
clockwise by an angle of 60º the glass element will
visibly drop down in the viewable window.
The call point switch will now change over its
contacts to operate the alarm.
Once testing is complete the unit needs to be
reset, the test key is rotated back anticlockwise by
an angle of 60º back to its original position. The
glass element should now raise up so it is level
again in the viewable window.

9) Replacement of glass element
If the break glass unit has been operated the
broken glass element can be quickly replaced.
The break glass cover plate is removed by
unscrewing the 4 off M4 cap head screws attaching
it.
Once the cover is removed the broken glass will be
free to be removed, clean out any other fragments
of glass carefully.
To fit the new glass element rotate the top cam
clockwise by an angle of 50º (use a 6mm Allen
key) this will than allow the glass to fit back into the
pocket it sits in, resting on the pivot point and test
cam, release the top cam to rest on the top of the
glass element.
Pivot point Test Cam Top Cam (rotate)
Replace the cover plate and tighten the 4 off M4
cap head screws.
Ensure the glass element is free to move under the
cover plate. This can be done by running through
the units test operation. See section 8 of this
instruction manual.
