Dared to replace a Door Entry Phone?? Discover How I did it.

After discovering that the door entry phone handset in my building had been out of order for some time, I decided to take matters into my own hands. Instead of paying the hefty fee of US$120 to have it replaced by the management office, I found a brand new one on Taobao for just US$10! Join me as I share my experience of installing this affordable solution, saving both time and money while ensuring our security needs are met.

Is there any sequence in order to connect/disconnect wires? I don’t want to blow any fuse.

[@MatthewKwan]

Well, in my case, I don't think my phone was powered. So, I did not care when I disconnect/connect

[@shilipsy]

I was wondering if you can help me please.
I recently moved into a new flat with a broken intercom. I identified it as a "ACET 22220 (2 Wire)". It has 6 wires inside (yellow, green, white, red, blk, blue). Cables yellow and red are in slot 5, black and blue are in slot 6 and the other cables are not connected at all.
I bought a bell 801 as replacement which 5 slots for wires "I R O T Z" which is different from my old ACET 22220.
Will this work as a replacement? And if so where would each cable go?

I found this from the web: interfoni.rs/wp-content/uploads/2019/08/Acet-22220-_2-zice-interfonska-slusalica-sema-prikljucaka-1.pdf
I am not sure Bell 801 is compatible or not but I think you it is safer bet to get Acet handset:

From my experience, you can try working on each function to see if it may work, e.g. to the ring sound first, then the open door button....

Thank you @@MatthewKwan

@@shilipsy Hope you can get it worked out.

U didn’t show which wires to connect where

[@MatthewKwan]

Hmm, the wires have to be connected differently according to your old handset. I had some help from the seller of the new handset after having shown a photo of the circuit board of the old handset to him. Point to note,
- a wire must be for door release,
- a wire must be mic out
- a wire must be incoming rings
- a wire must be incoming voice
So before you unconnect the wires, take some good photos to mark the numbers

[@zebrosco]

Did you have to shut off the power in your whole block to do the work?

[@MatthewKwan]

No, I did not.
