FWIW, 18VDC on the smoke unit with a 27 ohm resistor will result in 12 watts dissipated by the smoke resistor. Normal maximum is more in the lines of 7-8 watts maximum. The result will be good smoke for a short time, then as the wick gets caked, the smoke resistor will overheat and probably burn out. It's likely you'll also notice the smoke unit PCB will start to get brown as it gets overheated.
Good smoke, but not for too long.

Hi john

What are the typical voltage requirements for TMCC & Legacy smoke units. Do most TMCC & Legacy smoke units fall into the 7-8 max wattage limit.

Thanks,
