In the synchronous flasher control the oscillator is running at all times and the power to each set of flashers is turned on or off by the control circuit for that crossing. This allows any number of flasher sets at different crossings to controlled individually and yet flash in unison.
Two versions of the flasher output control are shown.
In OUTPUT 1 the lights are turned on when the control circuit goes to the common of the circuit.
In OUTPUT 2 the lights are turned on when the control circuit goes to the positive supply of the circuit or some other supply source.
In either case the PNP and NPN transistors above and below the LED's are turned on and the crossing lights will flash.
IF more than one set of flashers is used at a particular crossing the LED's could be wired in series so as to keep the number of output control circuits to a minimum. This is shown on the basic flasher schematic. (View)
