Hi, I hope one of you can help. My old Acet intercom handset broke and I bought an Acet701 to replace it with. All looks fine and I have a wiring diagram for the new handset, however the cable connectors are in different places and the old phone doesn't mark what each wire is currently going to/from so I'm not sure where to put them in the new handset. I have not yet disconneted the old one and have taken a photo showing the wires (bottom row) coloured orange, white, blue, white then underneith a light green one: Is there anyone who may know what each colour is or be able to work it out from my photo?
Thank you very much in advance!

One of the worst to work on lol.

Two types cannot see the numbering from here but.

6 or 2 are the common negative,
3 or 7 are door to handset speech
4 or 10 are handset to door
5 is the release
9 is the ringer.

If this is rented accommodation I recommend you get the landlords to change. Even if your fault, you can play about with the connections you will not blow anything up and it is elv or low voltage and will not harm unless of course you find the transformer and mess with that.

Thanks for the quick reply Workers (sorry it took me a few hours to see it)!
The problem is that there is no numbering or lettering on the old handset so I'm not sure which colour wire refers to what. Are you able to make a estimated guess at what each colour may refer to in my case. I gather that there are a number of different colour sets, have you come across this one?
If you are sure I won't fry anything then I'll make an estimated guess at what goes where - maybe I can rope someone into standing next to the front door whilst I remove cables one at a time to see what goes off...

you can check most of the connections by unscrewing the pcb in the phone trace the tracks on the pcb one will go to the lock button, two will go to buzzer one will be the common one will be the buzzer and if you trace the wires off the handset lead one will go to the common so you now know which is the common on the buzzer leaving just speech in and out,

Yep.

Take one wire out. see of speech works if not put back. You now have one speech line.
Another see if door opens.
Another to see if it rings.

If I get a weird one I just use the above and get the desired result.


Easier when used to them and as said can trace back, but as b4 you will not blow it up.

Cheers guys, I had some success today. Just in case this helps someone else the wires turned out to be as follows:
Orange: Core, White1: Buzzer, White2: Speaker, Blue: Mic, Green: Door Open. And in the new Acet701 the cables went in as follows:
3: Speaker, 4: Mic, 5: Buzzer, 6: Core, 7: Door Open

The only problem is that the new phone appears to be broken as the mic in the handset isn't working... grrrr... That'll teach me for buying cheap on the internet!..

Thank you again for your reply Workers and thanks for sticking with me on this one!
I'm going to risk looking a fool here but there is no mention in the wiring diagram that came with it about a 6th cable although there is a spare wire doing nothing in the handset that wasn't connected in the old one.
I think I may have confused things by calling the orange wire 'core', basically it appears to power the unit, without it in nothing works so could this in fact be the common neg?

Should be a 5 wire handset. So you would have had a spare.
Thats the new one so indeed the spare you have could be the negative you need.
It would be easier to look inside the door unit, see what colours are used and trace it back that way.
But your doing well for a novice
