I would like to install my ring doorbell 2 in a way that it also work with my current chime. However, I am having trouble figuring out if my existing chime is mechanical or digital. It’s a Nutone A-5859. One of the tubes say “L32ND73D”. Not sure which one is the model number. I am unable to find either model in ring chime compatibility list.
Also, unable to find the model in Nutone’s website. Can someone take a look at the attached pics whether it’s a mechanical or digital chime. And if it will work with ring doorbell2? I don’t want to mess up my existing chime making a mistake regarding diode?
The white sticker on one tube says, this bell works with a provided 16v transformer only". Is it safe to say I should have 16v current here? However, when I checked the ring button at the door, multi meter reading is zero, same is the case at the door bell itself. What can I be doing wrong here.
Would appreciate any help on this?
