Best replacement intercom handset - any foolproof suggetions?

[Henry55552]

Hi all,

The buzzer has gone on a vintage 1980s intercom - the rest of it works fine so wanted to just change the handset.

Can anyone recommend something that would work with this wiring?

There are 6 wires (this must include the power supply). There are two further black wires (shown) which lead to the buzzer itself.

Want to avoid having to have the whole building re-done!

Very grateful for any advice.

H

Post picture of the handset as a modern day replacement may be available

If the speech through the handset works then it might be quicker to replace only the buzzer. A picture of the buzzer might help to identify what type it is and whether there is an equivalent. Also the manufacturer's name and type for the handset.

At a wild guess it's a bitron handset

It's got an "E" on the logo - the back doesn't give a name - couple of photos attached.

Any suggestions gratefully received.

Thanks,

H

@ Bernard good suggestion. I had thought the same although all the big DIY chains (B&Q etc) don't seem to sell components. Is there anywhere you'd recommend?

Maplins is a good bet.

Ensign used Briton handsets .... Post picture of the buzzer and sizes, been repairing door entry systems for over 25 years , most buzzers will work but having the space to fit it inside the intercom handset is another issue !

 

[sparkymarka]

Your other option is to fit this at the side of the handset ...... eBay 111742422439
Or doorentrydirect. Sell them at around £7...

Thanks Bernard - I got one from them but unfortunately not one that fits or is audible (they suggested 12V).


@sparkymarka I've attached a picture of the original buzzer (about 1cm wide) - do you know if anything like this still exists? Alternatively do you know of a new handset that I could buy and wire up to the rest of the system?

No picture can you add some more pictures of the handset inc the buzzer inside

 

[Henry55552]

my bad. the buzzer is hanging at the bottom - I unplugged the right black wire when I was trying to test it (it was in no. 7 before).

 

[sparkymarka]

I take it you push the receiver in to open the door ( no separate button on the case ? ) if so then 90% sure it's an old bitron handset was used in SRS entry systems aswell .

Most maplin buzzers are DC, you probably require an AC buzzer, the Videx 512R mentioned would do, as probably would this:

This one does both AC and DC:

@sparkymarka Yes it is - it took me a while to work it out as the handset has never been wired up to open the door (we still use the yale latch) but just for speaking and buzzing (speaking still works). The button that is depressed when the handset is hung up has a logo of a key next to it. So I think you are right. Do you know of any manufacturers / models that might work?
