I'm thinking of putting 180k pull down resistors on these lines, so it would be nice to know what the actual input impedance is so I can calc the total current sink at 240vac.

I didn't know the actual input impedance..but I Think 40 meters is so long distance, so the signal will be deacyed and LOGO! can't sense it ...so try it but use a control cable to keep signal . Best wishes
