Are you hooking the 930 up to the power transformer? Are you trying to detect motion, or only when they press the doorbell? If you connect it at the transformer, then YES the camera, IR lights and even charging the battery become part of that 900ma limit. Instead you need to hook the 930 in series with the doorbell chime AFTER the Ring Pro power adapter. Then the 930 will respond to the doorbell chime just like it was connected to a plain-old doorbell. So DON'T follow the ELK 930 directions. Instead, connect it in series with the chime.
Came across this via Google search for Ring Pro + ELK 930, as I am in the same boat as the OP after installing my Ring Pro yesterday.
For years, I've had just a standard HeathZenith mechanical doorbell, tied to front and backdoor lighted doorbell buttons.
The 930 is installed on one leg of the doorbell transformer (16v/10va), which is mounted on the side of my electrical panel in the basement.
Been using the 930 contact closure output to drive a digital input on a control system, which in turn triggers a relay for a strobe light (think old-school phone-flasher, but for the doorbell, as it's hard to hear with music cranked, etc.).
I've now installed a Ring Pro in place of the front doorbell button. It works quite well so far (aside from the 2s delay between the button press and mechanical chime, which is a whole other topic), but I now either get random triggers or no change at all on the 930 contact closure output.
At one point the 930 output latched and never opened, but there was no trigger (this was all during the day while testing after I installed the Ring Pro).
I've read where some have installed standard window sensors right on the chime itself, which get triggered from the magnetic field when the solenoid moves.
This is certainly something to be considered, but it's apparently not 100% reliable, plus I'm not sure if I would get a trigger for both front + rear, not to mention I don't have extra wires for this at the chime.
I then read here about using a higher voltage transformer. I happened to have a Honeywell 24v/40va transformer on hand and tried it, but no change whatsoever.
There seems to be another potential solution here from ano, but I'm not quite sure how I would wire the 930 "in series with the doorbell chime AFTER the Ring Pro power adapter".
My Ring Pro came with the Pro Power Kit v2. This one attaches in parallel to the FRONT and TRANS terminals on the chime:
Can someone provide a wiring diagram as to how this would be done? I'm assuming it involves getting at the back of the chime terminals?
If so, would I put it on the TRANS lead? I'd still like to get a closure from both front and rear doorbell triggers.
Any other suggestions or potential solutions would be most appreciated!
