atcomsystems.ca/forum Forums Other TDM Phone Systems 1A2 and Comkey Telephones & Systems Executone 1A2?!

I have a new addition to the family coming. It's an Executone 16 button set very similar to a call director in appearance. It is a model # E-316R(B) Key Telephone Set. Does anyone know anything about this set? Is it really 1A2 or something else? It has 2 25 pair amphenols as I would expect to find on a key set this big. And the most important question- Does anyone have a practice for this gem? All searches on google have been fruitless. I would really like to not have to guess about the wiring in a set with 50 pairs. Thanks guys.

I'll check with a former E-Tone employee. See if he knows anything. I don't have a clue.

When I worked for them we installed ITT 1A2 sets.

Hi Sam, got your email, really long time since I heard that model and was on this forum but let's see if I can help.

Vintage stuff, from around the mid 70's

It is not a true 1A2 set but you can the line keys to work to work on a 1A2 I believe.

The original KSU for this was the TIE 10S. The set was OEMed by TIE to Executone. It was once OEMed to another company but I cannot remember who that was, I knew this because sometimes we would get a rebuilt from TIE that had their label on the bottom. It was just a more modern looking set then the tie 300's and Gray Whales. I think there was also a Executone E324 model as well.

Things that will not work without the KSU is common bell ringing (it was a tone), speakerphone and the intercom.

You may want to check with some of the guys that worked on the OLD tie (10S & 2050 systems) to see if they have a cut-down for the regular sets, it was very similar if not exact.

Sorry, I don't have a cut-down for it, My stuff went into a dumpster when I was divorced back in the late 80's.

Exactly. It is sort of like 1A2, more like Comkey 718/1434/2152. The line cut down is T, R, A and L. There's a common ground for the lamps. There is no ringer in the set, just an amplifier and speaker that repeats the tone that is sent in over the pair that feeds audio into it (I believe audio is on the yellow/orange and power for the amplifier is on the yellow/slate @ 24VDC). I've wired these into existing 1A2 systems, but it is no walk in the park. I used a 455A KTU from a Comkey 718 system to provide the tone ringing signal.

In a few days when it shows up, I'm sure I'll have some more questions. I'm just glad to know it CAN work with 1A2 and its not just a boat anchor. I'm kind of wondering if there's enough room to squeeze a small ringer like the one in a 2851 set. I forget the number... P1B or something? A speaker and amplifier is an interesting thing to find in there. I'm sure I can find a use for that if I can't make it work for it's intended purpose. Anyways... Thanks a bunch guys and I'll let you know when it shows up and how I make out.

If a bell doesn't fit, you may want to try and find a 90V buzzer and wire it to the CB of your 1A2 equip

I seem to recall that these phones have 24 volt lamps in them, but again, I am not positive about anything regarding them.

As long as they are similar to the 51A lamps, socket-wise, I should be fine. I have a pail full of 51A lamps laying around.
Otherwise I will make up some LED lamps for it. I've modified a few of my 6 button sets with white LED's instead of the traditional lamps. Cuts down the load on LB supply, and they last near forever. Just a 470 ohm (I think) resistor and the led soldered to the tabs. I'll find a pic and post it.

This is one of my crappier 6 button sets I put LED's in:



It doesn't look that glaring in person. My IPhone camera doesn't do it justice.

Here's a pic of the phone I'm getting:
