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

KA2 will power an HO-Scale locomotive at speed step 10 of 128 with headlights on for approximately 6 to 15 seconds (depending on the locomotive and the efficiency of the motor).

All TCS decoders shipping with dates codes as of November 2011 support the Keep-Alive feature.

To enable the Keep-Alive feature place a value of 2 in CV 182. This essentially disables DC mode and the decoder will remain in DCC operation during brief power interruptions.

These KA's are designed for a maximum track voltage of 16v.

MSRP is $26.95.(Picture courtesy of TCS.)
