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

13. Line Monitoring
On the BExBG10D-P and BExBG15D-P 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.

Synchronised Operation
All BExBG10D-P and BExBG15D-P 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 8).

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 8) 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
