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. 1a Fixing locations Public Mode Alarm.
Fig. 1b Fixing locations Private Mode Alarm.
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 enclosure, loosen the four M4 posi pan head
screws and withdraw the cover
Fig. 2 Accessing the Enclosure
To replace cover, check that the ‘O’ ring seal is in place.
Carefully push the cover in place. Insert M4 screws with fiber
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 beacons 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
16)

The voltage drop depends on:
- The total current draw if 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
For ambient temperatures over +45ºC the cable entry
temperature may exceed +70ºC. Therefore suitable heat
resisting cables and cable glands, rated to min. 75ºC must be
used.
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 PCBA located in the enclosure. See section 6 of this
manual for access to the enclosure.
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 Live/Neutral or +/-
terminals 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) AC Wiring
The Strobe is powered via factory installed wires connected to
the sounder. 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 D211-06-611
Fig 4. AC Terminals
10) DC Wiring
The Strobe 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 D211-06-611
Fig. 6 DC Terminals
11) Earthing
The unit has both internal and external earth terminals, (please
see fig 2).
Internal earthing connections should be made to the internal
earth terminal on the PCBA, (please see fig 4 for AC, fig 6 for
DC). The earth conductor should be at least equal in size and
rating to the incoming power conductors. The internal earth
bonding wire connects the PCBA earth terminal to the internal
earth terminal in the enclosure back box.
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.

12) End Of Line Monitoring (DC Units Only)
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
24V DC 3.9KΩ 0.5W
1KΩ 2W
48V DC 15KΩ 0.5W
3.9KΩ 2W
The resistor must be connected directly across the +ve and
-ve terminals of the sounder board, as shown in the following
drawing. 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.
Sounder EOL Beacon EOL
Fig. 7 End of Line Resistor Forming
Fig. 8a End of Line Resistor Placement – Sounder
For the Beacon, the resistor must be connected directly
across the +ve and -ve terminals as shown in the following
drawing. Form the resistor legs as shown in Fig. 7, remove
the +ve and –ve terminal plugs and fit the resistor across the
two terminal plugs before refitting them to the PCBA as shown
in Fig. 8. A spacing of at least 1/16” (1.58mm) must be
provided through air and over surfaces between uninsulated
live parts.

FIRE INSTRUCTION MANUAL
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.
