Here in Germany we have 12v for doorbells. Wo take a relais l, connect it to your hw and all is good.
While the bell is undoubtedly 240v (from the specs), and contains no transformer (from an answer to a customer question). it does NOT confirm or repute the voltage(s) used to switch/trigger the bell are 240v or and other voltage. No circuit or wiring diagram seems available, so you MUST confirm all voltages yourself - obviously carefully.
Hehe, I was waiting for some joke about the "ding-dong" effect I've recorded "ding-dong" from James Earl Jones, then I converted it to the proper format with a proprietary software of the doorbell manufacturer, and with the same software I've uploaded to the doorbell via RS-232
