2nd generation doorbell - does it need a resistor?
The help centre article for the 2nd generation Ring video doorbell (see table in the link below says: “ **resistor not needed when hardwiring"** [https://support.ring.com/hc/en-gb/articles/360045514872-The-difference-between-the-Ring-Video-Doorbell-1st-generation-and-Ring-Video-Doorbell-2nd-generation-](https://support.ring.com/hc/en-gb/articles/360045514872-The-difference-between-the-Ring-Video-Doorbell-1st-generation-and-Ring-Video-Doorbell-2nd-generation-) However the instruction manual for the 2nd generation Ring video doorbell (see attached) says at the bottom right on page 13 **“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.”** So which is correct? Does the 2nd generation Ring video doorbell need a resistor when hardwired, or not?

Hello there! I’ve been trying to find the same answer for the Ring Doorbell 4. I have a transformer but no chime. I contacted support via chat, where they told me to call. When I called I talked to two different support techs that could not answer for me and referred me to the OnTech number which also was a dead end. Does the Ring Doorbell 4 need a resistor if connected directly to a transformer?

I am replacing a second generation with a Ring video doorbell 3. If I already have the voltage adapter resistor in the wall, do I absolutely need to take that off the line to the Ring video doorbell 3? Or can I leave the resistor on the line? Would that hurt anything? Thank you.

Hi @MarkJRogers. It is not recommended to use a resistor with a Doorbell 3, and I would not connect it in line with your Doorbell.

Please define “trickle-charge”. How much current does the Ring Video Doorbell 2 actually draw from, say, a directly wired 24VAC transformer? I couldn't find this in the specifications. Thank you.

Hi guys, I tried to get in touch with Ring few times unsuccessfully so here I am looking for some help. WE currently have a hard wired (without chime) Doorbell 2, we are upgrading to a Pro 2. After installing the Doorbell 2 I found out by chance that a resistor was needed as I connected the Doorbell directly to the transformer. the resistor itself is very cheap (50C) but obviously Ring doesn t includes it to make our life more complicated. Now I have been trying very hard to find out definite answers from Ring to see if with the doorbell pro 2 I still need the resistor , no luck!!! I see that Caitlyn_Ring posted some links that again don't explain well what is needed... and that confusion about hard wiring is absolutely unnecessary... hard wiring means you are getting power supply via wires, weather or not you bypass the mechanical chime it is still hard wired. the installation manual for the pro 2 doesn t mention anything about resistor, so ... any definite answer?
