alternative connection

Hi, I would like to drive a relay (ideally 12v dc) to provide volt free contacts when the Ring doorbell is pressed whilst also charging the doorbell. Can anyone recommend a suitable relay and power supply to use?

The contacts will be connected to my alarm system to trigger a chime and create a datestamp on the system log.

Thanks in advance

Hey @Widlof. I wanted to step in and advise you of the power requirements for the Doorbell itself to ensure there’s no concern with the transformer. Can you let me know what model of Doorbell you have? You can also find the transformer power requirements on our website if you select the Doorbell you have and scroll down to the Tech Specs. :slight_smile:
