Replacing broken Entry Phone

[twall]

The buzzer in my entry phone is broken. Thought I could just buy one off Amazon, but I was wrong.
The old phone us anciist, no labels or branding. Does anybody have a clue as to what make / model I would need to replace this with?
Any help would be greatly appreciated.

How do you know it’s the buzzer ? And not the wire or button ?

At a guess it’s an urmet 730/1030/1130 handset ….

The buzzer sounds, but extremely faintly. The spring on the button is gone too, hense wanting to replace it.

This is the replacement ….look on intercomsrus….really good site to find out what handset you have and if or what is the replacement …

Yes, it looks like that might be the one. Do you know if there is an affordable modern unit can i easily replace it with? (Small wires to same numbered connectors preferably)
Appreciate the link you sent, but £85 and a horrible beige colour is not appealing

Personally I would go for a universal handset as they have separate mic and speaker adjusters inside the handset ….i have used the comelit one before ….see below anything else is a trial and error

Could anybody assist with wiring this up? I've spudied the diagrams and made a couple of attempts. Got the call buzzer and door release working, but not the speaker or micriphone

Thank you. Tired your suggestion @sparkymarka , wired like this, call buzzer works, but the door opener does not and there is a persistent ringing noise coming from both microphones, inside (when the receiver is off the hook) and out.
Had the call and opener working earlier, but the buzzing was there too

 

[sparkymarka]

This is how I would wire it ….

You may have to alter the volume pots in the handsets after…..

Thank you. It would seem there is a issue with the external microphone and or speaker. Wired it up without green wired in. Buzzer and opener works, no buzzing on external speaker, but buzzing on internal speaker when headset lifted. May need to settle with not being able to speak through the mics.
