Grade Crossing Flasher Controller

The Dallee Grade Crossing Light Flasher controller makes it easy to alternately blink two lights just like a regular grade crossing. The flash speed can be controlled by turning a dial on the board. By wiring just 1 lamp, a strobe effect, blinking light, can be accomplished.

Installation Instructions

1. Route power from a 6-20 volt power supply to the Common and Input terminals on the flasher controller (if DC, use the Common terminal for the negative lead).
2. Link the common wires from each light and attach them to the common terminal on the flasher.
3. Connect the remaining power wire for each light to the lamp one and lamp two terminals (one in each).

Three Rail Detection

Three rail detection is provided easily by using the outer rails to complete the common wire in the circuit.

Two or Three Rail Detection

Activating the flasher on a two rail layout requires the use of a detector, such as the Trak-DT or Trak-DTT.
This method can also be used with 3 rail operation. The upper rail would be the center rail or both outside rails.
