HI I recently bought the Ring Video Doorbell Wired to use with my existing chime. I've just opened the chime and it is a Greenbrook DHT01A-C (link to manual here http://www.greenbrook.co.uk/product-pdfs/DHT01A_Instructions.pdf) First question - I assume this will be compatible with the Ring Video Doorbell as it says it is 10.3V AC ? Second, in terms of the install I take it i just have to install the jumper cable across point 0 and 2 as per the manual (or the top left and bottom right terminals as shown on my attached photo)? Many thanks!
