It is important that a suitable power supply is used to run the
equipment. The power supply selected must have the
necessary capacity to provide the input current to all the
units.
The input current will vary according to the voltage input level
and the frequency of the tone selected. The current levels
shown above are for the tone resulting in the max. current
draw (tone 1 - 340Hz Continuous).
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 sounder 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 sounder 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 sounder 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
Ambient Temp. 40ºC 45ºC 50ºC 55ºC
Min. Rating of cables
and cable glands 90ºC 95ºC 100ºC 105ºC
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 / 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.
Warning – Hot surfaces. External surfaces
and internal components may be hot after
operation, take care when handling the
equipment.
Warning – High voltage may be present,
risk of electric shock. DO NOT open when
energised, disconnect power before
opening.

9.3 Line Monitoring
On E2xS2 DC units, DC reverse line monitoring can be used
if required. All DC sounders have a blocking diode fitted in
their supply input lines. An end of line monitoring resistor can
be connected across the +ve and –ve terminals. If an end of
line resistor is used it must have the following values:
24V DC Sounders
Minimum resistance 3K9 Ohms Minimum Power 0.5W
Minimum resistance 1K Ohms Minimum Power 2.0W
48V DC Sounders
Minimum resistance 15K Ohms Minimum Power 0.5W
Minimum resistance 3K9 Ohms Minimum Power 2.0W
The resistor must be connected directly across the +ve and
-ve terminals as shown in the following drawing. 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.
Fig. 8 End of Line Resistor Placement
10) Settings
10.1 Tone Selection
The sounders have 45 different tones that can be selected for
the first stage alarm. The sounders can then be switched to
sound second and third stage alarm tones. The tones are
selected by operation of a DIP switch on the PCB for both DC
and AC units. The tone table on page six shows the switch
positions for the 45 tones and which tones are available for
the second and third stages. To operate the sounder on
stage 1 simply connect the supply voltage to the normal
supply terminals (+ve and –ve for DC units, L and N for AC
units).
10.2 Volume Control
The output level of the E2x sounder can be set by adjusting
the volume control potentiometer (see Fig 4 for AC & Fig 6 for
DC). For maximum output, set the potentiometer fully
clockwise.
11) 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.
Warning - High noise levels above 85dB(A)
during operation. High levels of noise may
cause hearing loss, wear suitable ear
protection when equipment is in operation.
