Description
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.
The KA4 will power an HO-Scale locomotive with headlights on for approximately 6 to 20 seconds (depending on the locomotive and the efficiency of the motor).
This Keep-Alive® includes a Blue and a Black w/ White Stripe wire to attach it to a decoder.
Decoder Specifications:
- Dimensions: .52” x .52” x .45” or 13.22mm x 13.22mm x 11.55mm
- Connection: Hardwire (Other Harness Options Available)
- Input Voltage: 12-16V
Keep Alive® Decoder Compatibility
TCS Keep Alive® (KA) devices are designed to operate with all TCS (or any other Keep Alive® ready) decoders. Decoders with a “-KA” suffix include an extra Blue wire and a Black w/ White Stripe wire for hardwiring the KA to the decoder. Decoders with a “-KAC” suffix have a 2-Pin Connector for attaching the KA(x)-C. WAUX-KA(x) and KA(x)-C devices are not compatible with non-TCS decoder plug-in Keep Alive® interfaces.
Not all DCC decoders are Keep Alive® ready. TCS decoders use software to enable and disable KeepAlive, so if your decoder does not support Keep Alive®, it may not work. Keep Alive® supported code for TCS decoders was implemented fully by November 2012. If the date code in your decoder is before this date, Keep Alive® may never enable. CV's 250, 251, and 252 read as the month, day, and year of manufacturing.
If you would like to attach a Keep Alive® unit to a non-TCS decoder, you need to connect the wires across the output of the bridge rectifier on the decoder. You will need to consult your decoder manufacturer for a schematic or wiring diagram.
Installation Notes for TCS Decoders
- ALL TCS decoders are compatible with Keep Alive® devices.
- Connect the Keep Alive® wires to the decoder (Make sure you match the wire colors on the KA to same wire color on the decoder).
- That’s it! Your locomotive is ready to run over the most treacherous of tracks.
