Train Control Systems (TCS) 1455 - KA1-C Keep Alive - Multi Scale

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. 

Newly-redesigned and coming in at half the size of a KA3, the KA1 will power HO or N scale locomotives with approximately one-third of the capacitance of KA3/KA4 devices (depending on the locomotive and motor).

with 2-Pin Quick Connector

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.

Dimensions: 1.063" x 0.35" x 0.244" or 27mm x 8.9mm x 6.2mm

Scale: HO Scale N Scale

Input Rating: 12 to 16V

Installation Notes for TCS Decoders

1. ALL TCS decoders are compatible with Keep Alive® devices.

2. 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).

3. That’s it! Your locomotive is ready to run over the most treacherous of tracks.

One Year Goof Proof Warranty

All decoders are covered by a one year goof proof warranty. Please return in a small box.
You MUST register the failed decoder on our website at tcsdcc.com/warranty
Follow the instructions on the website before returning any decoders to TCS.
