For use in Class I Division II locations, in order to maintain
the db type protection, flameproof conduit seals and/or cable
glands must be used.
The cable gland entries have an M20 x 1.5 entry thread. Only
suitably rated and certified cable glands which must be
suitable for the type of cable being used and also meet the
requirements of the current Ex ‘db’ and Ex ‘tb’ flameproof and
NEC/CEC installation standards (tightening torque 10Nm).
When only one cable entry is used the other entries must be
closed with suitably rated and certified blanking plugs that
meet the requirements of the current Ex ‘db’ and Ex ‘tb’
flameproof and NEC/CEC installation standards (tightening
torque 10Nm).
All Installations:
To access the Ex d chamber, remove the four off M6 x 60
stainless steel A4-70 Cap Head cover bolts.
If the installation is made using conduit, openings must have
a sealing fitting connected as close as practical to the wall of
the enclosure, but in no case more than the size of the
conduit or 2” of enclosure, whichever is the lesser.
Electrical connections are to be made into the PCB / terminal
blocks / DIN rail provided.
Internal earthing connections should be made to the Internal
Earth terminal on the PCBA. The earth conductor should be
at least equal in size and rating to the incoming power
conductors.
On completion of the installation the flameproof joint surfaces
should be inspected to ensure that they are clean and that
they have not been damaged during installation. Flamepaths
are not intended to be repaired.
When fitting the flameproof cover ensure the cover is sitting
flat and correctly positioned on the base. Insert the M6 x 60
stainless steel A4-70 Cap Head cover bolts and fully tighten
down (tightening torque 3.5Nm), ensuring no gap is visible
between the cover and base of the enclosure.
If a high IP (Ingress Protection) rating is required then a
suitable sealing washer must be fitted under the cable glands
or blanking plugs.
The enclosure is non-conducting and may generate an
ignition-capable level of electrostatic charges under certain
extreme conditions. The user should ensure that the
equipment is not installed in a location where it may be
subjected to external conditions that might cause a build-up
of electrostatic charges on non-conducting surfaces.
The M12 Cap fitted to the top side of the unit is not a user
serviceable part and must not be removed during installation
and maintenance.
The GNExCP7 Call Point range can be supplied with the
following types of adapters:
M20 to ½” NPT
M20 to ¾” NPT
M20 to M25
It is important to note that stopping plugs cannot be fitted
onto adapters, only directly onto the M20 entries.
Any other adapters used must be suitably rated and ATEX /
IECEx / UKEx or NEC/CEC certified adapters.
12) Cable & Wiring Connections
Wiring methods shall be in accordance with CSA C22.1,
Canadian Electrical Code, Part I, Safety Standard for
Electrical Installations, Section 32; and CAN/ULC-S524,
Standard for Installation of Fire Alarm Systems.
The units come with two options for the terminal block.
A DIN rail version which has 8-way connection and allows for
limited wiring of EOL devices, or a 6 Way terminal block.
The PCB Terminal Version has a 6-way connector but is
designed to allow for full configuration with Series and EOL
devices in a number of wiring configurations.
For full wiring details see wiring diagrams D202-06-211
For EOL and Series device limitations and configurations see
Section 15. Fitting can be requested by E2S at the order

stage or added to the correct terminal blocks afterward. All
devices must comply with the requirements stipulated in
section 15.
Electrical Connections are to be made into the terminal
blocks using solid or stranded wire.
Wires having a cross sectional area between 0.5 mm² to
2.5mm² (AWG 20 – 14) can be connected to each terminal
way.
If an input and output wire is required the 2-off Live/Neutral or
+/- terminals can be used. If fitting 2-off wires to one terminal
way the sum of the 2-off wires must be a maximum cross
sectional area of 2.5mm².
Strip wires to 8mm. Wires may also be fitted using ferrules.
Terminal screws need to be tightened down with a tightening
torque of 0.45 Nm / 5 Lb-in.
When connecting wires to the terminals great care should be
taken to dress the wires so that when the cover is inserted
into the chamber the wires do not exert excess pressure on
the terminal blocks. This is particularly important when using
cables with large cross sectional areas such as 2.5mm².
13) Testing unit operation
The break glass unit can be tested without the need to
break/replace the frangible glass element.
A test key (Plastic Key Supplied with unit) 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 90º 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 90º to its original vertical
position. The glass element should now raise up so it is level
again (horizontal) in the viewable window.

14) 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 test cam clockwise by
an angle of 90º (use test key supplied) this will than allow the
glass to fit back into the pocket it sits in, resting on the pivot
point and test cam, ensure the plunger shaft is resting on the
top of the glass, it might need to be pushed up slightly to
achieve this.

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 13 of this instruction manual.
15) End-of-Line and Series Devices
All models can be fitted with series resistors, end-of-line
monitoring resistors, monitoring diodes and zener diodes if
supplied with direct current up to 48Vdc and limited to a
maximum total power consumption no greater than 6.224W.
Min. resistor values and current limitations must be observed
depending on supply voltage and type of components fitted. If
a combination of resistors / diodes / zener diodes is used,
values for all components must be observed and lowest
current limit for either component becomes overall limit.
Current limitation for units fitted with end-of-line resistors,
diodes or zener diodes must be ensured by using a current
limited power supply or fitting a current limiting resistor at the
control panel (not provided).
The following table 2 shows limitations for all possible
variations:
