So a ring operates at what 16-24v AC. What we have here is seemingly sending 240v to a 24v device... if the protection circuit is any good then it might have just blown a fuse on input voltage. If not then well it's likely fried. If you are handy with a meter it shouldn't be rocket science to see how bad it might be. Didn't you question at any point taking mains voltage to a low power device?
