Hello, my name is XXXXX XXXXX X am here to help you with all your electrical needs. I would like to thank you for choosing Just Answer. What we need to do to figure this out is look closely at the wiring diagram, depending on where that intercom wire originates from you need to go to that source and look at what terminals the wires are under. So for R that wire goes to the speech unit..go to that and look at color scheme. Same for T that wire also goes to speech unit. To double check that these are in fact the same wires you can use a multimeter to check them if you know how to do this,if not I will instruct you.
I would not no the color code the electrician used originally. I am not familiar with a communal box,can you post a picture?
Hello my name is XXXXX XXXXX X will be happy to answer your home improvement or electrical question
1) You mention that you have 3 remaining wires. Are these station wiring that originates from the communal box?
2) Are these in pairs? ie, Do you have a white/blue paired with a blue/white, a white/orange paired with a orange/white and a white/green paired with a green/white? I am trying to determine if you have a standard telephone type of cabling that utilizes these colors?
2) How many handsets are you trying to connect?
1) OK, very good... thanks for the reply
2) In the standard telephony color code. the wire pairs start out as follows in sequential order: Line 1 will be the blue pair, Line 2 will be the Orange pair and Line 3 will be the green pair. Since you are rewiring one intercom, most likely you just need the white/blue & blue/white pair. Refer to the color code breakout below:
White/Blue = Tip or Transmit
Blue/White = Ring or Receive
White/Orange = Tip or Transmit
Orange/White = Ring or Receive
White/Green = Tip or Transmit
Green/White = Ring or Receive
3) Not sure what term they used in the directions, but the industry standard is T for Tip or Transmit and R is for Ring or Receive.
Hope this helps.........If you have any additional questions, let me know and I'll be glad to answer them for you.

1) I was unable to locate a wiring diagram on the internet for your particular model. Any chance that you could scan or take a picture of the diagram and post it here so I can view it?
2) Are the wires hard-wired directly to the intercom unit or does it have a wall jack that the wires terminate into?
3) T should be for the microphone and R should be for the speaker
