Hello all -

I've been browsing the forum, but can't seem to find exactly what I'm looking for. I have an ITT 501 C Shoebox KSU, (I think it's a 501C, gray cover with an ITT logo in the lower right corner).

So far I've hooked up 2 keysets, and am having lots of fun with the system in general.

The KSU came with a 183981-101-PAK card, which I believe is for intercom functionality between the keysets. I have a number of 10v buzzers, and want to have a go at getting the intercom functionality online.

Problem is, I don't know where to start. Can anyone help? I've seen some posts about what leads to conenct the buzzers to in the keysets, but after that, things get a bit fuzzy. I've also reviewed the schematics over at kadiac.org; but I'm still lost. Even assuming I knew how to wire the stuff up, I'd still be helpless as I don't even know how to use it.... (i.e. what buttons to push to signal another keyset).

Any help is appreciated!

Thanks
Matt
