BExCP3A-PB
Manual Call Point – Push Button
For use in Flammable Gas and
Combustible Dust Atmospheres.
1) Introduction
The BExCP3A-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 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 no monitoring resistors, diodes or
zener diodes.
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.
2) Ratings and Markings
All units have a rating label, which carries the
following important information: -

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 / C60079-7:2017
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: Aluminium Pressure Die Cast Body
LM6
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 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.
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 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. The external earth lug
should be located between the two M5 washers
provided and securely locked down with the M5
spring washer and two locknuts.

7) Cable connections
There are 3 off cable entry holes suitable for
M20x1.5 Ex e approved cable glands or stopping
plugs
The unit can be wired in a number of different ways
depending whether normally open or normally
closed contacts are required. See wiring schematic
D150-06-001 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
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 push button unit can be tested without the
need to replace any element.
To test, lift the cover lift flap to reveal the push
button. The button should be pressed into the body
to activate the unit and place it into the operated
condition.
The call point switch will now change over its
contacts to operate the alarm.
Once testing is complete the unit needs to be reset
from the operated condition.
Rotate the push button anticlockwise by an angle
of 55º, see guide alignment marks on button and
cover, shown below (1). The push button should
pop back up to its original position.
Ensure that the push button has also twisted back
clockwise by 55º to its original position see guide
marks on button and cover, shown below (2).
The unit is now reset.
1. On operated unit 2. Button should pop
Twist push button up and twist back to
Anticlockwise 55º original position to
reset
Note: use

circled to indicate
the push button’s

Resetting an operated unit is the same as
resetting a tested unit.
