2.7 Ingress Protection Ratings
The product is rated for ingress Protection as follows:
IP rating: IP66
Type rating per UL50E / NEMA250: 4 / 4X / 3R / 13
To maintain the ingress protection rating, the cable entries
must be fitted with suitably rated, certified cable entry and/or
blanking devices during installation.
2.8 Electrical Ratings
It is important that a suitable power supply is used to run the
equipment. The power supply selected must have the
necessary capacity to provide the input current to all the
units.
The input current will vary according to the voltage input
level. The current levels shown above are for the worst-case
input voltage and flash setting resulting in max. current.
For detailed current ratings of the device please see Section
13.
3) Special Conditions of Use
Special Condition for safe Use as stated on the Type
Examination Certificate DEMKO 14 ATEX 4786493904X /
CoC/IECEx ULD 14.0004X:
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. If conduit is used for installation, seal conduit
within 18 inches from the enclosure.

4) Location and Mounting
The location of the beacon should be made with due regard
to the area over which the warning signal must be visible. It
should only be fixed to services that can carry the weight of
the unit.
The D2xB1LD3 beacon should be secured to any flat surface
using the two 7mm fixing holes in the feet of the base. The 2-
off mounting feet supplied with the unit must first be fitted to
the base using the 2-off M5 X 8mm countersunk screws
provided. Additional feet are available as spare parts if
required. The unit can also be pole mounted using the ¾”
NPT Entry in the centre of the base. See Fig. 1.

5) Access to the Enclosure
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 fibre
washers and tighten to 3Nm torque.
6) 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 4), 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 13)
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 as follows:
2-off M20 x 1.5 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.

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.

7) Cable Connections
Electrical connections are to be made into the terminal blocks
on the PCBA located in the enclosure. See section 5 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 +/- 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.
8) Wiring
2-off 2-way terminal blocks are provided on the beacon for
power. There are 2-off +ve & 2-off –ve terminals in total.
8.1 Wiring Diagrams
Fig. 3 D2xB1LD3 DC Simplified Block Diagram
Fig. 4 D2xB1LD3 Terminals
8.2 Line Monitoring
DC reverse line monitoring can be used if required. All
beacons 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:
24V DC applications
Minimum resistance 3K9 Ohms Minimum Power 0.5W
Minimum resistance 1K Ohms Minimum Power 2.0W
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. 5a, 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. 5b.
A spacing of at least 1/16” (1.58mm) must be provided
through air and over surfaces between uninsulated live parts.
Fig. 5a End of Line Resistor Forming
Fig. 5b End of Line Resistor Placement
9) Earthing
The unit has both internal and external earth points, (please
see fig 6).
Internal earthing connections should be made to the internal
earth point on the PCBA, (please see fig 6). The earth
conductor should be at least equal in size and rating to the
incoming power conductors. The internal earth bonding wire
connects the cover earth point to the internal earth terminal in
the base.
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 4mm2in 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.

(Example shown: 01 = Flashing 1.33Hz)
11) Maintenance, Overhaul & Repair
Maintenance, repair and overhaul of the equipment should
only be carried out by suitably qualified personnel in
accordance with the current relevant standards:
IEC/EN60079-19 Explosive atmospheres - Equipment repair,
overhaul and reclamation
IEC/EN60079-17 Explosive atmospheres - Electrical
installations inspection and maintenance
To avoid a possible ELECTROSTACTIC CHARGE the unit
must only be cleaned with a damp cloth.
Units must not be opened while an explosive atmosphere is
present.
If opening the unit during maintenance operations a clean
environment must be maintained and any dust layer removed
prior to opening the unit.
