5) Special Conditions for Safe Use
Repair of the Flame Path is not permitted.
Figure 1: Flame Path
The plastic horn is not anti-static, and the metallic enclosure
has a non-conductive coating. These 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.
6) Product Mounting and Access
6.1. Location and Mounting
The sounder should be secured to any flat surface using the
three 7mm fixing holes (see figure 2). The angle can then be
adjusted as required but the mounting restrictions must be
observed (see outline drawings for details, D199-05-001 for
STExS1F and D199-05-021 for STExS1R). This can be
achieved by loosening the two large bracket screws in the side
of the unit, which allow adjustments in steps of 18°.
Figure 2: Fixing Location for STEx[S1R/S1F] Sounder.
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.
The enclosure provides IP66 protection and is suitable for
installation in exterior locations providing it is positioned so that
water cannot collect in the horn, and the cable entry is sealed.
6.2. Access to the Flameproof Enclosure
Warning –Hot surfaces. External
surfaces and internal components
may be hot after operation, take
care when handling the equipment.
In order to connect the electrical supply cables to the sounder
it is necessary to remove the flameproof cover to gain access
to the flameproof chamber. To access the Ex d chamber,
loosen the M4 grub screw on the sounder cover. Open the
enclosure by turning the sounder cover counterclockwise and
remove the cover, taking extreme care not to damage the
flameproof threads in the process (See figure 3).
Figure 3: Accessing the Explosion Proof Enclosure.
On completion of the installation, the flameproof threaded joint
should be inspected to ensure that they are clean and that they
have not been damaged during installation.
Ensure that the ‘O’ ring seal is in place and undamaged.
When fitting the flameproof cover ensure the thread is
engaged correctly. Fully tighten the cover all the way, ensure
no gap is visible between the cover and base of the sounder
enclosure. Tighten the M4 grub screw.
7) Installation Requirements
7.1. Installation Standards Compliance
Warning –High voltage may be
present, risk of electric shock.
DO NOT open when energised,
disconnect power before opening.
The sounder must only be installed by suitably qualified
personnel in accordance with the latest issues of the relevant
standards.
ATEX / IECEx installation standards:
EN60079-14 / IEC60079-14: Explosive atmospheres -
Electrical installations design, selection and erection.
EN60079-10-1 / IEC60079-10-1:Explosive atmospheres -
Classification of areas. Explosive gas atmospheres.
EN60079-10-2 / IEC60079-10-2:Explosive atmospheres -
Classification of areas. Explosive dust atmospheres.
The installation of the units must also be in accordance with
any local codes that may apply and should only be carried out
by a competent electrical engineer who has the necessary
training.
7.2. Cable Selection and Connections
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.

Sheet 4 of 7
Electrical connections are to be made into the terminal blocks
on the PCBA located in the flameproof enclosure using solid
wire 0.5-4mm² / AWG 20-12 or stranded wire, sizes 0.5-
2.5mm² / AWG 24-14. Wire insulation needs to be stripped
8mm. Wires may be fitted securely with crimped ferrules.
Figure 4: Wire Preparation.
Terminal screws need to be tightened down with a tightening
torque of 0.45 Nm / 5 Lb-in. An 8-way terminal block is
provided on the AC Sounder, and a 6-way terminal block is
provided on the DC Sounder.
Figure 5: STExS1 Entries and Terminal Block Location.
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.
Earthing
Both AC and DC sounder units must be connected to an earth
according to EN/IEC 60079/14. The units are provided with
internal and external earth terminals which are both located on
the terminal chamber section of the unit (see figure 5).
Internal earthing connections should be made to the PCB
terminal block or to the Internal Earth terminal in the base of
the housing using a ring crimp terminal to secure the earth
conductor under the earth clamp. The earth conductor should
be at least equal in size and rating to the incoming power
conductors.
External earthing connections should be made to the M5 earth
stud, using a ring crimp terminal to secure the earth conductor
to the earth stud between the two M5 stainless steel flat
washers, then reassemble the M5 spring washer and tighten
the M5 nut to ensure that the cable lug is secured against
loosening and twisting. The external earth conductor should be
at least 4mm2in size.
7.3. Cable Glands, Blanking Elements & Adapters
For high ambient temperatures the cable entry or the cable
branching point temperatures may exceed:
•70ºC at entry point.
•80ºC at branching point.
Therefore, suitable heat resisting cables and cable glands
must be used, with a rated service temperature at least as
stated in the table below:

Table 2: Min. Ratings of Cables & Cable Glands.
Cable Glands
Appropriate cable glands to be customer supplied.
The cable entries have an M20 x 1.5 –6H entry thread. Only
suitably rated and ATEX / IECEx certified cable glands must
be used. They must be suitable for the type of cable being
used and also meet the requirements of the current installation
standards EN 60079-14 / IEC60079-14.
Blanking Plugs
When only one cable entry is used the other entries must be
closed with suitably rated and certified blanking plugs as per
type of approval.
Any unused cable entries must be closed with suitably rated
and ATEX / IECEx certified blanking plugs.
Ingress Protection
If a high IP (Ingress Protection) rating is required, then a
suitable sealing washer must be fitted under the cable glands
or blanking plugs. A minimum ingress protection rating of IP6X
must be maintained for installations in explosive dust
atmospheres.
For combustible dust applications, the cable entry device and
blanking elements shall be in type of explosion protection and
shall have an IP 6X rating.
Adapters
The STEx sounder 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 certified adapters.
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
50mm, whichever is the lesser.
