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
10).
