Hi my name is Shaw aka Dr.Fix-It , Your online expert ready to assist you... It would help to provide some more details to look into this matter,
What is the brand & model of the the existing door bell / intercom?
Is the bell and intercom all in one housing and just replacing the door bell portion?
What is the color code on the bell and the color code on the door bell button?
Do you have a multi-meter to verify voltages or connections?
What is the replacement bell brand and model #?
Let me know, thanks.
ok so the existing door bell button has four wires, are two pairs tied together or does the button actually have 4 separate terminals ?
A bell may have two tones, one for a front door and another for a back door :
If all wires are for bell, then two may not being used, in which case can just connect the two wires that when close switch will sound the chime.
If still not sure, please take clear pictures of the existing button wiring and use paperclip on above toolbar to attach it here, thanks.
So the red and black when closed enable the speaker of the intercom and the white and green closed sound a chime... What if keep the red and black jumped together and wire the white and green to the new button? Should keep speaker enabled and only sound chime when button is pressed, unless the contacts need to be opposite of one another I.e the speaker contacts need to open when the chime contacts close, then would need to either find two pole switch or relay to drive the two circuits.
