Keep Alive®

Keep Alive® technology eliminates current issues from poor track and electrical pickups. For sound decoders specifically, Keep Alive® prevents sound interruptions and engine stalling that can occur from hiccups in power delivery. When power to your locomotive is interrupted, Keep Alive® delivers 5-8 seconds of additional power to keep your locomotive running through dead spots on the track. Everything continues to run: motor, lights, and sounds. Cutting power to your layout will activate the Keep Alive® device, so don't be surprised if you still hear the locomotive making sounds for several seconds. Nothing's wrong - that's Keep Alive® doing its job!

Keep Alive® (KA) Decoder Compatibility

The TCS KA’s 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 Keep Alive plug socket have a 2-Pin socket for attaching the KA-P.

Installation Notes for TCS Decoders:

1. Connect the Keep-AliveTM wires to the decoder (Make sure you match the wire colors on the KA to same wire color on the decoder).

2. Program CV 182 to a value of 2.

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

NOTE: If you wire this backwards (blue to black w/white stripe) you will VOID the warranty and destroy this device.
