I would sugest that you use a relay to control the smoke unit. Then use one of the function outputs of the decoder to operate the relay.
Most decodrs will handle only about 100 milliamps per function. I will bet the smole unit is way above that. That is why you should use a relay.
The decoder will turn the relay off or on - the n/o- n/c contacts of the relay could operate the smoke unit. Could operate off the track power.
Would be a drain of the DCC system power output.
