Special Condition for safe Use as stated on the Type
Examination Certificate DEMKO 14 ATEX 4786493904X /
CoC/IECEx ULD 14.0004X / UL21UKEX2131X:
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.
The equipment shall only be used in an area of at least
pollution degree 2, as defined in IEC 60664-1.
6) Product Mounting and Access
6.1. Location and Mounting
The location of the combined alarm horn and beacon should
be made with due regard to the area over which the warning
signal must be visible and audible. It should only be fixed to
services that can carry the weight of the unit.
DxC2 Alarm Horn and Strobe to a flat surface via the two 9.7
x 6.7mm, 147mm pitch fixing holes in the mounting feet of the
sounder section and the two 7mm fixing holes in the feet of
the base.
The equipment is not to be mounted with the horn facing
upwards.
Fig. 1 Fixing locations.
6.2. Access to the Enclosure
Warning – High voltage may be
present, risk of electric shock.
DO NOT open when energised,
disconnect power before opening.
Warning – Hot surfaces. External
surfaces and internal components
may be hot after operation, take
care when handling the equipment.
To access the enclosures, loosen the four M4 posi pan head
screws of the beacon and loosen the four M4 posi pan head
screws of the sounder and withdraw the covers.
Fig. 2 Accessing the Enclosures.
To replace covers, check that the ‘O’ ring seals are in place.
Carefully push the covers in place. Insert M4 screws with fibre
washers and tighten to 3Nm torque.
7) 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 units 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.
When selecting the cable size consideration must be given to
the voltage drop over the length of the cable run to ensure the
min. input voltage at the point of use (voltage range, see section
15)
The voltage drop depends on:
- The total current draw of the devices installed on this
cable run
- The wire size and total length of the cable run,
determining the total resistance of this cable run
- The minimum output voltage supplied by the power
supply
The voltage drop and input voltage at the point of use can be
calculated as follows:
Total Wire resistance =
Wire resistance / 1000ft x length of cable run x 2
(length of cable run needs to be multiplied by two to account for
two wires going to and from the unit)
Total current draw =
Current draw per unit x number of units
Voltage Drop = Total current draw x Total wire resistance
Minimum output of power supply =
Min. voltage at point of use + voltage drop
The entries are available as one of the following options:
2-off M20 x 1.5 thread & 1-off ¾” NPT thread;

2-off ½” NPT thread & 1-off ¾” NPT thread
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.
NPT plugs should be greased before insertion.
8) Cable Connections
Electrical connections are to be made into the terminal blocks
on the PCBAs located in the enclosures. See section 6 of this
manual for access to the enclosures.
The Sounder and Beacon are supplied connected by default.
In order to power the beacon and sounder separately, the link
wires between the units must be disconnected.
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 +/- terminals of the
beacon or 3-off +/- terminals of the sounder 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 0.56 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.
9) Wiring
The beacon is powered via factory installed wires connected
to the alarm horn. The wires connecting the alarm horn and
strobe can be removed if the user wishes to power the strobe
separately. For further wiring schematics refer to document
D211-06-651
Fig. 4 Terminals
10) Earthing
The beacon bas has both internal and external earth points,
(please see fig 5). The sounder PCBA also has earth terminals,
(see fig 4).
Internal earthing connections should be made to the internal
earth point on the beacon, (please see fig 5). The earth
conductor should be at least equal in size and rating to the
incoming power conductors. The internal earth bonding wires
connect the covers to the internal earth points in the bases.
External earth connections should be made to the M5 earth
stud, 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.
Fig. 5 Earth locations
11) End Of Line Monitoring
On DxC2 DC units, dc reverse line monitoring can be used if
required. All DC units 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:-
Min. Resistance Min. Power
3.9KΩ 0.5W
1KΩ 2W
The resistor must be connected directly across the +ve and
-ve terminals of the PCBA, as shown in the following diagrams.
Whilst keeping its leads as short as possible, a spacing of at
least 1/16 inch (1.58mm) must be provided through air and over
surfaces between uninsulated live parts.

adjusting the volume control potentiometer (see Fig 8). For
maximum output, set the potentiometer fully clockwise.
Fig. 8 Location of field controls
12.2. Tone Selection
The DxC2 alarm horns have 64 different tones. The tones are
selected by operation of the tone setting DIP switches (see
Fig. 9 & 10) on the PCB. The alarm horns can also be
switched to sound the second, third and fourth stage alarm
tones. The tone table (Table 1) shows the switch positions for
the 64 tone and which tones are available for the second, third
and fourth stages.
12.3. Flash Rate Setting
The D2xC2LD3 beacons can produce different flash patterns as
shown in Table 1. The flash patterns are selected by operation
of the flash setting DIP switch on the PCB, Fig 10.

D2xC2LD2 Alarm Horn and LED
For use in Hazardous Locations
1) Warnings
 DO NOT PAINT
Avertissement:
 NE PAS PEINTURER
2) Rating & Marking Information
2.1 Public Mode Fire Alarm Ratings
The D2xC2LD2DC024 is certified for use a as public mode audible and visual alarm device in accordance with UL464 & UL1971 /
UL1638.
For use in public-mode fire alarm systems the equipment must be installed without the wire guard or plastic lens cover on the beacon.
The beacon must be set to one of the certified flash patterns of 1Hz, 1.33Hz or 2Hz (for DIP switch settings see section 10).
For light output ratings of the beacon see section 12.
The sounder section produces a sound pressure level above 75dB(A) at 10 feet:
For Fire Alarm applications, the Sounder Volume must be at the highest setting, (see volume control section).
For fire alarm use, the temporal pattern tone No. 12 as per the tone table provided in these instructions must be selected.
This tone produces a minimum sound pressure level of:
CAN/ULC-S525: 100.4dB(A)* at 10 feet.
(*anechoic room)
UL464: 92.2dB(A)† at 10 feet.
(†reverberation room)
Testing of synchronization requirements of UL1971 & UL1638 / CAN/ULC-S526 were conducted by UL using a total of 6 units connected
to the same wire run. Auto-synchronization does not require the use of any external sync modules or protocols. Providing the correct
cable has been selected (see section 6) an unlimited number of units will remain synchronized when powered from the same source.
2.2 Private Mode Fire Alarm Ratings
The D2xC2LD2DC024 is approved for use as Audible and Visual Appliance for use in Fire Alarm Systems – Private Mode.
For private mode fire alarm use the beacons must only be fitted with clear or red plastic lens covers and must be set to one of the
certified flash patterns of 1Hz, 1.33Hz or 2Hz.
For light output ratings see section .
3) Light output for Fire alarm use
In order to meet the requirements for UL 1971, (D2xC2LD2DC024 when used with 1Hz, 1.33Hz or 2Hz Flash rates and without plastic
lens cover and wire guard only), the installation must be carried out to the correct NFPA standards and guidelines.
