The picture was just to show the 223 module, nothing else. I don't need a KSU, only 2 wires from classic phone line and a power transformer. That's why I propose to plug the phone line directly on the 2565 and the M16 for 4A system. But I suppose it's a stupid idea...

So what do you have? Transmitter with or with out end to plug to amp? Speaker with or with out end to plug to amp? (without means spade tips on wires) and transformer with or without? Are you planing on using the amp plug on the phone? If so what are you plugging it into? If you have the M16 cable, and plug connectors on everything it all just plugs into it than wires to the phone.

Thanks again for your help and patience.
I have a 2565hkms with end amp connector, a 108A speaker with end, a transmitter/switch with end and a small end black module (the same you can see on the picture or in any 82A/B/C set between speaker and transmitter/switch ends). I don't have any transformer at this time but I will buy it. I'm planing to use the 2565hkms amp to plug into the speaker end + transmitter/switch end and the small black module end ( what is it ? ). As is, I only have to find where to plug the 18 VAC wires to power up the speaker and transmitter/switch (directly on the 2565hkms), then I have to plug the 2 wires of the single phone line on the 1 & 26 slots of the 2565hkms.

Sorry it won't work that way, your best bet is the 82 block for what you're trying to do. Guess maybe Ed understood what you were doing. All 223 adapter is for is to house all the other stuff when using the M16 cable.

You will definitely need the 82 type block to handle this. I have one available for sale if you are interested, probably the last one on the planet including the transformer. Send me a private e-mail if you are interested and I will figure out what it's worth.

The 223 adapter allows you to hard-wire the speakerphone set into the phone. It was designed for use ONLY with 2830/2831 sets due to the lack of available spare pairs on 10/20 button sets. Technically, it can be used with a 2565HKM, but I don't have access to the documentation to make it happen.

Yes, you are on the right track about sending the line into the phone on the first pair, but you won't have any lights or hold functionality. I assume you already know that much based upon your previous posts.

You guys are great - I enjoy just reading through your posts. Amazing collective knowledge! It's also amazing how many people want those 4A sets - see what Charlie's Angles did for the 4A.

Don't you need to change out the dial in order to use it the 4A. I seem to recall that you could use the 4A with a special order 2500 set that had extra contacts on the dial. Wasn't that also true for a key set - that you need extra control leads in order to go off hook with the 4A and dial without picking up the headset. Does this make any sense or, as usual, am I confused?

The 2565 set the original poster mentioned comes factory equipped with the special dial that takes the phone off-hook whenever a button is pressed by closing the violet and green/white leads. I believe that the single-line phone that was equipped with this dial was a 2500MMG but don't hold me to it. The 2564 series of phones was not equipped with these dials, however the wall mount (2851CM, etc.) was. I am not quite sure how a 4A would work with a wall phone.

Actually, there were two single-line type phones designed for use with the 4A system in mind. The rotary version was the 500R/S, and the TT version was the 2500S.

Heck... I think I still have a 2500S. In green, no less, with a speakerphone set to match.

Keep the peace(es).

Ive got a working single line 4A. The best speaker phone ever made.

I've successfully connected a 4A to an older single line set without the 82 or 223 adapter blocks. They are extremely difficult to find. It does require cutting the plugs and hard wiring. I only wired it to the line, so you have to take the phone off-hook to dial, then turn on the speakerphone, and then hang up the phone. But it works great, especially for answering calls with the touch of a button.
I have a number of black 4A Precision sets for sale,, and one WE in beige, if anyone is interested.
