Beacon Location and Mounting
The location of the beacons should be made with due regard
to the area over which the warning signal must be visible.
They should only be fixed to services that can carry the
weight of the unit.
SAFETY WARNING: The BExBG15D and BExBG10D 15
and 10 joule beacons must be mounted with their flashdome
in a position between upright and 90º as shown.
90º
The beacons should be securely bolted to a suitable surface
using the 7mm diameter boltholes in the stainless steel U
shaped mounting bracket (see figure 1). The angle can then
be adjusted as required but the mounting restrictions must be
observed (see above). This can be achieved by loosening the
two large bracket screws in the side of the unit, which allow
adjustment in steps of 18°. On completion of the installation
the two large bracket adjustment screws on the side of the
unit must be fully tightened to ensure that the unit cannot
move in service.
SAFETY WARNING: The flashdome guard must not be
removed from the unit at any time.

Access to the Flameproof Enclosure
In order to connect the electrical supply cables to the beacon
it is necessary to remove the flameproof cover to gain access
to the flameproof chamber. To achieve this remove the four
M6 hexagon socket head screws (see figure 2) and withdraw
the flameproof cover taking extreme care not to damage the
flameproof joints in the process.
Note the four M6 screws are Class A4-80 stainless steel
and only screws of this category can be used on these
beacons. It is therefore important that these screws and their
spring washers are kept in a safe place during installation.
On completion of the cable wiring installation the flameproof
joints should be inspected to ensure that they are clean and
that they have not been damaged during installation. Also
check that the earth bonding wire between the two casting
sections is secure and the 'O' ring seal is in place. When
replacing the flameproof cover casting ensure that it is square
with the flameproof chamber casting before inserting.
Carefully push the cover in place allowing time for the air to
be expelled. Only after the cover is fully in place should the
four M6 Stainless Steel A4-80 cover bolts and their spring
washer be inserted and tightened down. If the cover jams
while it is being inserted, carefully remove it and try again.
Never use the cover bolts to force the cover into position.

Power Supply Selection
It is important that a suitable power supply is used to run the
beacons. The power supply selected must have the
necessary capacity to provide the input current to all of the
beacons connected to the system.
The following table shows the input current taken by the
various units:-
