Do know which of the AC input terminals on the DSC PC-1616 is positive and which one is negative? They aren’t labeled for which one is which.

Most systems it doesn’t matter.
Yeah: AC has no polarity (though I would still follow what the wiring diagram says, which is usually black to black/B/hot, white to white/W/neutral, & green to green/G/ground).
