I've removed my (recently died) wired alarm system and replaced with a Ring alarm.
The old alarm panel was powered from a fused spur, fed from a dedicated MCB on the consumer unit. I'd like to put the Ring alarm base station on the wall in this location, but also utilise the existing alarm...
It depends which Ring doorbell you are trying to install, for example the Ring Doorbell Wired model may be able to use the power supply from an existing doorbell, but it cannot operate the existing chime at all, whereas other models can operate existing compatible chimes...
