Line Monitoring

On BExCBGL2-L2D DC units, dc reverse line monitoring can
be used if required. All DC sounders 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. Flash Rate Settings

The BExB2L2D beacons can produce different flash patterns
as shown in Table 1. The flash patterns are selected by
operation of the flash setting DIP switch on the PCB, Fig 9.
