BExCP3C-BG
Manual Call Point – Break Glass
With Resistor Modules
For use in Flammable Gas and
Combustible Dust Atmospheres.
1)
Introduction
The BExCP3C-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 and IECEx scheme.
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:
Monitoring resistors up to 1.5W per module
Monitoring diode
Monitoring Zener diode
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 T75ºC Db’ 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:
Aluminium Pressure Die Cast Body
LM6
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 or
gases that may attack metals, 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.

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 centers.
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 both internal and external earth
terminals.
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.
