Configuration of doorbells from two inputs: electro-lock control with INT-SCR

Hello
I wanted to seek advice from colleagues on how to solve the subject of doorbells from two entrances and so:

Front door main entrance for friends guests etc mounted outside INT-SCR lock controlling electro lock on it bell button OC type output wire controlling from INT-SCR to relay in switchboard.

Side door entrance to workshop and company office for friendly local companies and colleagues also mounted INT-SCR controlling electro-lock on it bell button OC type output controlling from INT-SCR to relay in distribution board.

Garage door - panel door also mounted INT-SCR controlling the door drive on it bell button OC type output controlling from INT-SCR to the relay in the distribution board someone not familiar with it can always try to call from the SCR from the garage door so it's fitting to connect it somehow but not necessarily with the side door?

I need that pressing the bell button on the SCR triggers a sound but different for each door so that I know where to go to open it.
I have prepared two wires on the wall from the switchboard 3x1 cable how to arrange the bells two next to each other but it fits probably from the same company but with different sounds mounting different bells it will look poor. It is possible to remove these different bells from the housings and mount them in a different housing but in which one ? Ordinary box is also poor for a hallway - any ideas ?

Another option:
I have the installation and the EDL-612 loudspeakers installed for the sound system I am planning to have an HQM amplifier maybe I could somehow connect under the loudspeakers ? This way I have sound from the bells in every room and not only where the wires are led.

Another option is:
All INT-SCRs plugged into the Integra 128 plus in the vestibule, by the living room and in the company's utility rooms a TSI keypad is planned - is it possible to implement the bells on the TSI ?

Connect the bell buttons from INT-SCR to the inputs of the Integra and control the bell, e.g. pressing the button at the front door gives a short pulse, from the side door a longer pulse and from the garage door the longest or intermittent pulse, or the front door gives 1 bell, the side door 2 bells, the garage 3 bells.

.

Also an interesting solution i.e. need one bell preferably some kind of electronic 12V and try to drive this from the Integra outputs.

Or a 230v bell controlled from the integra output via a relay. Such will certainly be easier to get.

And that's probably the easiest and cheapest way to embrace it.
Although there are bells on the internet for 12v.
