AC Wiring
A 4-way terminal block is provided on the AC chamber beacon
for power. There are 2-off Live and 2-off Neutral terminals in
total. A 4-way terminal block is provided on the AC cover
beacon for power. There are 2-off Live and 2-off Neutral
terminals in total.

Line Monitoring
On BExCBGL2-05D-P 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 diode
or 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 a minimum resistance value of 3k3Ω and a
minimum power rating of 0.5 watts or a minimum resistance
value of 500Ω and a minimum power rating of 2 watts.
The resistor must be connected directly across the +ve and -
ve terminals as shown in the following drawing. The resistor
leads should be kept as short as possible.

13 Wiring the combined beacon/beacon for
simultaneous operation
Both beacon sections can be wired to the same input supply
so that they operate simultaneously or they can be wired to
separate input supplies so they can be operated independently
(see wiring diagrams D210-06-711 or D210-06-715).
If the chamber and cover sections are connected to the same
input supply. The incoming cables should be connected to the
input terminals on the cover section beacon board and the two
link wires, that are supplied with the unit, should be used to link
the supply from the interconnecting terminals on the cover
section beacon board down to the supply terminals on the
chamber section beacon board.
