This link is a bit more informative as it is mostly in non-technical terms...

That link is perfect, the bit about "What does Listed Central Station mean" was what I needed.
Though I understand the desire to have the particulars pertaining to UL listing, to me it's a rather simple matter. Either you conform to an objective, outside, respected standard (UL listing), or you don't. Knowing that UL is a respected testing organization, and that they know a hell of a lot more than I do about what matters for competent monitoring, is something that I can accept or reject without knowing the details.
But this much is obvious -- criticizing the standard as "marketing fluff" is a smokescreen meant to obscure the fact that they don't meet it.
I understand on an emotional basis about smokescreens, but if there's no publicly available info on what a given "objective, outside, respected standard" means, then it means as much as the AAA moody ratings on Bear Stearns/GM/Chrysler/Lehman/AIG/Freddie/Fannie/Merrill did. Consumer Confidence in heavily private "public standards" is rightfully gone, we're currently in a recession/depression because not enough people questioned the folks creating the standard.
Thanks again to everyone who helped, much appreciated.
