5) Specific Conditions of Installation
ATEx/IECEx & UKEx Installations:
The cable entries have two M20 x 1.5 –6H entry thread and a
single ½” NPT thread. If the installation is made using cable
glands, only suitably rated ATEx/IECEx or UKEx 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.
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.
Any unused cable entries must be closed with suitably rated
and UKEx certified blanking plugs.
For high ambient temperatures the cable entry temperature
may exceed 70ºC or the cable branching point temperature
may exceed 80ºC and therefore suitable heat resisting
cables and cable glands must be used, with a rated service
temperature at least as stated below:
NEC / CEC Installations:
The cable entries have two M20 x 1.5 –6H entry thread and a
single ½” NPT thread. If the installation is made using cable
glands, only suitably rated and UKEx 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 for NEC & CEC.
If the installation is made using conduit, openings must have a
sealing fitting connected within 18” of enclosure.
Any unused cable entries must be closed with suitably rated
and certified blanking plugs.
All Installations:
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.
Only the explosionproof cover is to be used for access to
the enclosure for installation, service and maintenance.
6) Specific Conditions for Safe Use
Flameproof threaded joints and cemented joints are not permitted to
be repaired.
7) Product Mounting and Access
7.1 Mounting
The D1x Alarm Horn may be secured to any flat surface using at
least two of the three or four 7mm fixing holes. 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.
Fig 1: Mounting Locations
The Equipment must not be installed with the horn facing upwards
of horizontal.
7.2 Installation procedure
a. Secure the D1x unit to a flat surface via the three 7mm
fixing holes in the mounting bracket.
b. Remove the explosionproof cover of the alarm horn by
unscrewing it, taking care not to damage the
explosionproof threads in the process (Refer to section
7.4).
c. Fit an M20/NPT suitably rated cable gland or conduit entry
into the hole in the enclosure and connect the field wiring
to the appropriate alarm horn terminals as shown in D190-
06-005 (AC) or D190-06-001. (DC). The power supply
terminals are duplicated so that units may be connected
in parallel. An end of line monitoring resistor may be fitted
to DC units only (see section 10). If the second and third
M20/NPT entries are not used, suitably rated stopping
plugs must always be fitted.
d. Replace the explosionproof cover of the loudspeaker,
taking care not to damage the explosionproof threads.
Tighten fully.
7.3 Hornless Variants
The D1x Sounder is also available as a variant with no horn fitted
in the factory. The Horn threaded nose portion has a fitment
thread of 1-3/8” – 18 UNF (to BS1580 or ANSI B1.1). The
customer is responsible for sourcing and correctly fitting a suitable
horn that meets all of the relevant safety requirements.

7.4 Access to the Explosionproof Enclosure
Fig 2: Accessing the enclosure
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. Take extreme care not
to damage the explosionproof threads in the process.
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 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.
8) Installation Requirements
8.1 Safe Installation Requirements
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.
The product must only be installed by suitably qualified personnel
in accordance with the latest issues of the relevant standards.
The installation of the units must also be in accordance with the
NEC / CEC and any local regulations and should only be carried
out by a competent electrical engineer who has the necessary
training.
8.2 Cable Selection and Connections
Electrical connections are to be made into the terminal blocks on the
PCBA, 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. Terminal
screws need to be tightened down with a tightening torque of 0.45
Nm / 3.5 Lb-in.
When selectingthe cablesize, consideration must begiven to theinput
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 the
sounders connected to the line.
AC: 1.0 - 2.5mm2/ AWG18 - AWG12
DC: 0.2 - 2.5mm2/ AWG24 - AWG12
Fig 3: Wire Preparation.
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.
8.3 Earthing
Fig. 4 Earth Locations
The unit has both a primary internal and secondary external earth
fixing point.
Internal earth connections should be made 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 but at least a minimum of 0.82mm2 /
18AWG in size.
External earth connections can be made to the M5 earth stud (see
Fig. 4), using a ring crimp terminal to secure the earth conductor
to the earth stud. The external earth conductor should be at least
4mm2 in size.
The external earth crimp ring should be located between the two
M5 plain washers provided and securely locked down with the M5
spring washer and M5 nut.
8.4 Cable Glands, Blanking Elements & Adapters
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.
To maintain the ingress protection rating and mode of protection,
the cable entries must be fitted with suitably rated cable entry
and/or blanking devices during installation.
If entries are fitted with adaptors they must be suitably rated for
the application. Fitting of blanking elements into adaptors is not
permitted.
Adapters
The D1x 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.
