4) Installation
4.1 Safe Installation Requirements
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.
The Equipment must not be installed with the horn facing
upwards of horizontal.
The equipment has not been assessed as a safety-related
device (as referred to by Directive 94/9/EC Annex II, clause
1.5).
For ambient temperatures over +50ºC the cable entry
temperature may exceed +70ºC / the cable branching point
may exceed 80ºC. Therefore suitable heat resisting cables and
cable glands must be used, with a rated service temperature of
at least 90ºC.
To maintain the ingress protection rating and mode of
protection, the 2-off M20 and 1-off M20/NPT cable entries must
be fitted with suitably rated cable entry and/or blanking devices
during installation. If a high IP (Ingress Protection) rating is
required then a suitable sealing washer must be fitted under
the cable gland. A minimum ingress protection rating of IP54
must be maintained.
Only the flame proof cover is to be used for access to the
enclosure for installation, service and maintenance.
Connections are to be made into the terminal blocks using
solid or stranded wire, sizes 0.5-2.5mm2/ AWG 20-14. Wire
insulation needs to be stripped 6-7mm. Wires may be fitted
securely with crimped ferrules. Terminal screws need to be
tightened down with a tightening torque of 0.4 Nm / 3.5 Lb-in.
Earthing connections should be made to the Internal Earth
point on the casting.
Check that the ‘O’ ring seal is in place between the two
castings.
4.2 Mounting
Fig. 1 Fixing locations.
The D1x Alarm Horn may be secured to any flat surface using
the three 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.
4.3 Installation procedure
a. Secure the D1x alarm horn to a flat surface via the three
7mm fixing holes in the mounting bracket.
b. Remove the flameproof cover of the alarm horn by
unscrewing it, taking care not to damage the flameproof
threads in the process (Refer to section 5).
c. Fit an M20x1.5 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 fig. 6 (AC) or fig 8. (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 12). If the second and
third M20x1.5 and or NPT entries are not used, suitably
rated stopping plugs must always be fitted.
d. Replace the flameproof cover of the loudspeaker, taking
care not to damage the flameproof threads. Tighten
fully.
4.4 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.
5) Access to the Flameproof Enclosure
In order to connect the electrical supply cables to the alarm
horn it is necessary to remove the flameproof cover to gain
access to the flameproof chamber. This can be achieved by
unscrewing the flameproof cover (counter-clockwise), taking
extreme care not to damage the flameproof threads in the
process.
Fig. 2 Accessing the Flameproof
Enclosure.
On completion of the cable wiring installation the flameproof
threads should be inspected to ensure that they are clean and
that they have not been damaged during installation. Also
check that the ‘O’ ring seal is in place, on the thread diameter
in contact with the flat face of the flameproof cover. When
replacing the flameproof cover ensure that it is tightened fully.

6) Volume Control
The output level of the D1x alarm horn can be set by adjusting
the volume control potentiometer (see Fig 3). For maximum
output, set the potentiometer fully clockwise.
D1xS2AC / D1xS2DC / D1xS1DC / D1xS1AC
Fig. 3 Location of field controls
7) Tone Selection
The D1xS1 & D1xS2 units have 64 different tones that can be
selected independently for the first and second stage alarms.
The tones are selected by operation of the tone setting DIP
switches 1 & 2 (see Fig. 3) on the PCB. The alarm horns can
also be switched to sound the third and fourth stage alarm
tones. The tone table (Table 1) shows the switch positions for
the 64 tones on first and second stages and which tones are
available for the third and fourth stages dependent on the
Stage 1 DIP switch setting.
8) Stage Switching Polarity (DC Units Only)
The D1xS2 and D1xS1 DC alarm horns have the facility to use
either +ve or –ve switching to change the tone to the second,
third and fourth stages. For –ve switching connect the two
headers on the pcb to the left-hand (marked –ve) and centre
pins. For +ve switching connect the headers to the right hand
(marked +ve) and the centre pins. (Refer to Fig. 4)

stage 4 tone.
For units set up for +ve switching (refer to 9.1):
Stage two (S2) operation : Power +ve and –ve, link a +ve
supply line to the S2 terminal. Dip switch 2 alters stage 2 tone.
Stage three (S3) operation : Power +ve and –ve, link a +ve
supply line to the S3 terminal. Dip switch 1 alters stage 3 tone.
Stage four (S4) operation : Power +ve and –ve, link a +ve
supply line to both the S2 & S3 terminals. Dip switch 1 alters
stage 4 tone.
Fig. 8 DC Terminals
11) Earthing
The unit has both a primary internal and secondary external
earth fixing point.
Internal earth connections should be made to the internal Earth
terminal (see Fig. 3 and 4. It should be fitted to the internal
earth point using a ring crimp terminal to secure the earth
conductor.
In addition, external earth connections can be made to the M5
earth stud (see Fig. 2), using a ring crimp terminal to secure
the earth conductor to the earth stud. 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.
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.
12) End Of Line Monitoring (DC Units Only)
On D1xS1DC & D1xS2DC units, dc reverse line monitoring can
be used if required. All DC alarm horns have a blocking diode
fitted in their supply input lines. An end of line monitoring diode
or 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 a minimum resistance value of 3k3 ohms and a
minimum power rating of 0.5 watts or a minimum resistance
value of 500 ohms and a minimum power rating of 2 watts.
The resistor must be connected directly across the +ve and -ve
terminals as shown in the following drawing. The resistor leads
should be kept as short as possible.
