13)
Synchronised Operation
All BExBG15D and BExBG10D beacons that are connected
to the same supply line will have 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 Figure 4).
14)
Flip-Flop Operation
Two beacons 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 figure 4) 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.
15) End of Line Monitoring (DC Units)
On the BExBG15D and BExBG10D DC beacons, 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 3k3 ohms and a minimum wattage of 0.5 watts or a
minimum resistance value of 500 ohms and a minimum
wattage of 2 watts.
