End of Line Monitoring (DC Units)
On BExCS110-05D DC units, dc reverse line monitoring can
be used if required. All DC units have a blocking diode fitted
in their supply input lines on both the sounder section and the
beacon section. 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 3k3 ohms and a minimum
wattage of 0.5 watts or a minimum resistance value of 500
ohms and a min. wattage of 2 watts. If the sounder and
beacon sections are wired to separate power supplies then
an end of line monitoring component can be used in each
section.
17)
Synchronised Operation
All BExCS110-05D units that are connected to the same
supply line will have a synchronized sound output and a
synchronised flash rate at one flash every second. To ensure
that the units will be synchronised check that the pin header
is not fitted, i.e. the two header pins are not shorted together
(see Figures 4 and 5).
18)
Flip / Flop Operation
Two units can be mounted close to each other to form a flip-
flop operation, where the beacons will flash alternately. To
achieve this mode of operation, fit a pin header to the flip-
flop header pins on the electronics board, i.e. the two header
pins are shorted together, (see figures 4 and 5) on one of the
two beacons. The first flash on the beacon that has the
header fitted will be delayed by ½ second. The two beacons
will then flash alternately every ½ a second.
