TCS Keep-Alive® (KA) devices are used to supply power to decoders during times of power interruption due to dirty track or problematic track work.

  • 2x Purple wires for Speaker + and Speaker -


  • Blue wire for connecting light functions and Keep Alive®


  • Black with White stripe wire for connecting Keep-Alive®


  • Tan wire for CAM input


  • Pink wire for Function Output 4
