2.6 Electrical Ratings
3) Special Conditions of Use
When used for a Group III application, the surface of the
enclosure may store electrostatic charge and become a
source of ignition in applications with a low relative humidity
<~30% relative humidity where the surface is relatively free of
surface contamination such as dirt, dust, or oil.
Guidance on protection against the risk of ignition due to
electrostatic discharge can be found in EN TR50404 and IEC
TR60079-32.
End user shall adhere to the manufacturer’s installation and
instruction when performing housekeeping to avoid the
potential for hazardous electrostatic charges during cleaning,
by using a damp cloth.
To maintain the ingress protection rating and mode of
protection, the cable entries must be fitted with suitably rated,
certified cable entry and/or blanking devices during
installation. If conduit is used for installation, seal conduit
within 18 inches from the enclosure.
Equipment with the flare horn shall not be installed with the
flare higher than horizontal (to avoid accumulation of dust).
The equipment incorporates metal parts isolated from earth,
having capacitance values exceeding the limits permitted in
the standards of certification. Mounting bracket – 10.33pF.

4) Location and Mounting
The location of the loudspeaker should be made with due
regard to the area over which the warning signal must be
audible. They should only be fixed to services that can carry
the weight of the unit.
The E2x loudspeaker should be secured to any flat surface
using the three 7mm fixing holes on the stainless steel U
shaped mounting bracket. See Figure 1. The required angle
can be achieved by loosening the two large bracket screws in
the side of the unit, which allow adjustment of the
loudspeaker in steps of 18°. On completion of the installation
the two large bracket adjustment screws on the side of the
unit must be fully tightened to ensure that the unit cannot
move in service.

5) Access to the Enclosure
To access the enclosure, remove the four M4 posi pan head
screws, M4 spring and plain washers and withdraw the cover.
Fig. 2 Accessing the Enclosure.
To replace cover, check that the ‘O’ ring seal is in place.
Carefully push the cover in place. Insert and tighten down M4
screws, spring and plain washers in the order shown above
and tighten down.
6) Selection of Cable. Cable Glands, Blanking
Elements & Adapters
When selecting the cable size, consideration must be given
to the input current that each unit draws (see Table 1), the
number of sounders on the line and the length of the cable
runs. The cable size selected must have the necessary
capacity to provide the input current to all of the sounders
connected to the line.
The dual entries can be ordered with one of the following
options:
2-off M20 x 1.5 thread
2-off ½” NPT thread
1-off M20 x 1.5 & 1-off ½” NPT thread
To maintain the ingress protection rating and mode of
protection, the cable entries must be fitted with suitably rated,
certified cable entry and/or blanking devices during
installation. If conduit is used for installation, seal conduit
within 18 inches from the enclosure.
For ambient temperatures over +40ºC the cable entry
temperature may exceed +70ºC or the cable branching
temperature may exceed +80ºC. Therefore suitable heat
resisting cables and cable glands must be used as per table
below

If a high IP (Ingress Protection) rating is required then a
suitable sealing washer must be fitted under the cable glands
or blanking plugs.
For use in explosive dust atmospheres, a minimum ingress
protection rating of IP6X must be maintained.
For use in explosive gas atmospheres, a minimum ingress
protection rating of IP54 must be maintained.
7) Cable Connections
Electrical connections are to be made into the terminal blocks
on the PCBA located in the enclosure. See section 5 of this
manual for access to the enclosure.
Wires having a cross sectional area between 0.5 mm² to
2.5mm² 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 / 4 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.
8) Line In Wiring
A 10-way terminal block is provided on the Line in
loudspeakers. There are 2-off Common, 2-off 15W/25W, 2-off
7.5W/12.5W, 2-off 3W/6W, 2-off 1W/2W and 2-off Earth
terminals in total.

8.3 Line Monitoring (Line in Units Only)
On E2xL15 & E2xL25 loudspeakers, DC line monitoring can
be used if required. All Line in Loudspeakers have a blocking
diode fitted in their supply input lines. It should be noted that
each loudspeaker has a 1M ohm bleed resistor connected
across the blocking capacitor and this should be taken into
account when selecting the value of the end of line
monitoring resistance. The end of line monitoring resistor can
be connected across the terminals on the end of line unit. If
an end of line resistor is used it must have the following
values:
70V Line in Loudspeaker:
Minimum resistance 3K9 Ohms Minimum Power 0.5W
Minimum resistance 1K Ohms Minimum Power 2.0W
100V Line in Loudspeaker:
Minimum resistance 15K Ohms Minimum Power 0.5W
Minimum resistance 3K9 Ohms Minimum Power 2.0W
The resistor must be connected directly across the terminals.
Whilst keeping its leads as short as possible, a spacing of at
least 1/16” (1.58mm) must be provided through air and over
surfaces between uninsulated live parts.
1W 3W 7.5W 15W C
2W 6W 12.5W 25W C

10) Maintenance, Overhaul & Repair
Maintenance, repair and overhaul of the equipment should
only be carried out by suitably qualified personnel in
accordance with the current relevant standards:
EN60079-19
IEC60079-19
Explosive atmospheres - Equipment repair,
overhaul and reclamation
EN 60079-17
IEC60079-17
Explosive atmospheres - Electrical
installations inspection and maintenance
To avoid a possible ELECTROSTACTIC CHARGE the unit
must only be cleaned with a damp cloth.
Units must not be opened while an explosive atmosphere is
present.
If opening the unit during maintenance operations a clean
environment must be maintained and any dust layer removed
prior to opening the unit.
