2) Rating & Marking Information
2.1 Public Mode Fire Alarm Ratings
The D2xB1XH1 and D2xB1XH2 are certified for use as public
mode visual alarm devices in accordance with UL1971 Third
Edition and UL1638 Fifth Edition / CAN/ULC-S526 Fourth
Edition.
For use in public-mode fire alarm systems the beacon must
be installed without the wire guard or plastic lens cover.

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.

Table 1: 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.
For detailed max and surge 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 D2x 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 M4 X 12mm 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.
Fig. 1 Fixing Location for Public Mode
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 fiber
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 section 13), 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 2-off M20 x 1.5 thread, 2-off ½” NPT thread &
1-off ¾” NPT thread
For ambient temperatures over +45ºC the cable entry
temperature may exceed +70ºC. Therefore suitable heat
resisting cables and cable glands, rated to min. 85°C 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.

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 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.
8) Wiring
3-off 2-way terminal blocks are provided on the beacons for
power. There are 2-off +ve, 2-off –ve, 2-off Earth.
8.1 Wiring Diagrams
Fig. 3 D2xB1XH1 & D2xB1XH2 Simplified Block Diagram
Fig. 4 D2XB1H1 & D2xB1H2 Terminals
8.2 Line Monitoring
On D2xB1XH1 & D2xB1XH2 DC units, DC reverse line
monitoring can be used if required. All DC 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:
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. 8a, 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. 8b.
A spacing of at least 1/16” (1.58mm) must be provided
through air and over surfaces between uninsulated live parts.
Fig. 5 End of Line Resistor Forming
Fig. 6 End of Line Resistor Placement
9) Earthing
The unit has both internal and external earth terminals,
(please see fig 3).
Internal earthing connections should be made to the internal
earth terminal on the PCBA, (please see fig 5 for AC, fig 8 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.
End of Line Resistor

10) DIP Switch
Please note that the D2xB1XH1 & D2xB1XH2 beacons have
a DIP Switch that is NOT customer configurable. This should
only ever be set to ‘00’.
Fig. 7 DIP Switch setting ‘00’
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:
EN60079-19
IEC60079-19
Explosive atmospheres - Equipment repair,
overhaul and reclamation
EN 60079-17
IEC60079-17
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.
