Hmm here's a bit more info:
Pg 5, section 2.08, (e): The intercom is accessed by dialing a 2 digit intercom number.
I don't know if the first number would be 0 or 1. So I figured I'd try both. Some signal pins don't buzz at all, no matter what I do. Others (so far 0, 5, 7 and 9 will buzz). But here's the deal.
I press 0, then the station number 4 times. Works every time on the 4th push, on the pins I listed. I know this thing doesn't support 9,999 stations, but perhaps the KSU is configured for 20?
Off to do some more reading.

Sorry Ed, didn't see your post.... that could be it as well.. I hope not, but I've looked these relays up before and they are still made. I wonder if maybe popping the cover off and giving them a good spraydown with some contact cleaner would do the trick.....

You're right. The 2012B was a little wall wart. I was thinking of the Big rack/wall mount power supply that supplied A & B Battery, 10V, 18V, & Ring Generator. There were a bunch of iterations of it depending on how much amperage, which voltages etc. But Old-Timers syndrome is creeping in and I can't remember anything anymore.

Originally posted by Matt1964: I wonder if maybe popping the cover off and giving them a good spraydown with some contact cleaner would do the trick..... I was going to suggest that, since actually getting to the contacts themselves might be a bit tough. Those relays are packed pretty tightly on the card for sure. Sam, my preference for an external power supply would be the Elgin EAK-6 or a Western Electric 79B5. The WECO unit included an interrupter, so it provided all of the needed voltages, plus lamp flash, lamp wink and interrupted ringing. Regardless, is still would be a major undertaking to backfeed a 601 KSU with one of these. I think that if I reached that point, I'd just put in a 620A panel for line cards and a 641A for intercom and be done with it.

Matt, if you are starting to add stuff to the 601, it's probably time to go to a 501 cabinet. And the EAK-6 power supply that Ed mentioned. The 601 power supply doesn't have any 'spare' power for running more stuff. And mounting an expansion rack is going to be problematic, at best. This thing is going to look like Johnny Cash's Cadillac, but won't run near as well! John C. (Not Garand)

How about an old fashioned ITT/SC/WE 501? The floor mount unit was pretty big, but the wall mount unit wasn't bad.
Six card slots, a full sized power supply, a real interruptor and room for an intercom (unless you wanted a 207).

..... now come on guys!!!! Ya got some extras to send me? Actually, if I were to change the KSU out, I'd go with whatver the WE equivelant is. I just like thier stuff better, I don't know why. Anyway, latest on the intercom. Use with a rotary - buzzer goes every time. Use with a touch tone - you have several options: 1. Press one, then the number you are trying to bzzzzz twice. 2. Press any other number, then the number you are trying to bzzzzzzzzz 3 times. 3. Press the number you are trying to bzzzzzzz 4 times. Pretty consistent. Rotaries work great... DTMF... not so much. I'm about to try a different deskset, not sure I trust the keypad on the one I was using. But I think it's a case of the daughterboard not being very clever. Or, as I like to call it: Dual Tone Misunderstanding Fill in your favorite adjective here

Sounds like a bad touch-tone adapter card on the intercom card to me. Make sure that all of the pins are properly-aligned between the main card and the piggyback card.
I'm pretty sure that I have the full compliment of WECO panels and power supply if you are serious.
Problem is, you won't have the luxury of the MOH slot, which would require yet another panel (641A). Sorry, I mentioned that 641 was for intercom; it is the 642A). While these panels might look more "impressive", they take up a lot more room than you have to spare. Let's stick with the 601.

Yep, I agree. Plus unless one of you guys can get me on somewhere as a 1A2 repairman.... well.. man, I'm just starting to become competent with the 601, and it's been over a year.
Also, the pins are in alignment - one other thing, I don't know if you remember, but I originally had this card with my KSU. We couldn't get it to work so I got one off you.
The adapter card from mine does the same as yours, on your main card.
I must have touched my old "main" intercom card too many times, cause it's just plain old dead.
So I don't know if it's the adapter card, or the main card..... but I suspect I have 2 bad adapter cards, since it works peachy keen with rotary.
Dunno where to go from here, but it sorta looks like back to C19 land....

OK, so the C-19 is in the process of being reinstalled (which it needed anyway, don't know what I was thinking when I put it in.... like Ken told me when he was here, there is a system for wiring up these 25 pair cables/devices. Apparently I hadn't yet "go it" when I put in the intercom.
Anyway, a question. I'm guessing the paging card looks to the signal pins on the KSU for it's cue to activate. If I backfed 1 sig terminal from the C-19, is it possile this would work, or would I be inviting disaster? I'm guessing without the intercom card in the KSU, the sig terminals aren't hooked to anything... but I thought I'd throw the question out anyway.
Thanks Matt
