5) Special Conditions of Safe Use
Special Condition for safe Use as stated on the Type Examination
Certificate 06ATEX 0421554X / CoC IECEx ULD 14.0012X:
End user shall adhere to the
manufacturer’s installation and
instruction when performing housekeeping to avoid the potential for
hazardous electrostatic charger 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.
Equipment with the flare horn shall not be installed with the flare
higher than horizontal (to avoid accumulation of dust).
6) Product Mounting and Access
6.1 Mounting
The D2xS2 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.
6.2 Installation procedure
a.
Secure the D2xS2 unit to a flat surface via the three 7mm
fixing holes in the mounting bracket.
b. Remove the cover of the alarm horn by unscrewing it,
taking care not to damage the threads in the process
(Refer to section 6.3).
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 D252-
06-005 (AC) or D252-06-001. (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 9). If the second and third
M20/NPT entries are not used, suitably rated stopping
plugs must always be fitted.
d. Replace the cover of the unit, taking care not to damage
the threads. Tighten fully.
6.3 Access to the Enclosure
Fig 2: Accessing the enclosure
To access the 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 threads in the process.
On completion of the installation the 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 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.
7) Installation Requirements
7.1 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 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.
7.2 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 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 the
sounders connected to the line.
Solid Wire: 0.5 - 4mm
2
/ AWG20 - AWG12
Stranded Wire: 0.5 - 2.5mm
2
/ AWG24 - AWG14
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.
