I keep seeing conflicting information on this. When wiring directly to a transformer (no existing chime) do i need to add a resistor?
The manual states Yes:
“If wiring directly to a doorbell transformer, connect a 25 ohm, 50W wirewound resistor in series with one of the doorbell wires to protect your Video Doorbell.”
The product how to page states No:
Ive skimmed through many community pages with conflicting info as well. Here are a couple:
Does 2nd generation Ring video doorbell 2020 need a resistor or can it be directly wired to a AC transformer if I do not have an existing doorbell
Which one is it?
Here is the other community post referencing
@user72785. The manual (US) for the Doorbell 2nd Generation is correct. You do need a resistor when hardwiring it directly to a transformer. The Help Center pages that you are referring to are for the UK.
