Help! video doorbell with wirless chime adaptor

[erik_ag]

Hi,

I'm trying to set up a Hikvision video doorbell to trigger a honeywell digital chime. I ran into an intermittent issue, where the power kit was not functioning properly- it was not sending enough voltage to the doorbell, and too much to the digital chime, frying the transformer. I'm guessing this happens because the digital chime does not have the same properties as a mechanical chime and the power kit malfunctions. (the digital trigger does wire up the same as a mechanical chime so you can replace one with the other)
I added a 12 ohm 25w wire wound resistor into the circuit so the digital trigger reacts the same as a mechanical chime (similar rest/trigger V and A)
This seems to have solved the issue in parallel.

My question is, should that resistor be in series or parallel? or does it matter?
Drawing attached- Hikvision setup is the same as Ring which had better drawings.

Thanks for the help!

if you want to limit the current to the transformer, your resistor goes in series with 1 of the transformer leads.

I'm not trying to limit current to the transformer.
The chime trigger seems to have a much higher resistance than a mechanical chime.
I'm trying to set this up in a way that the power kit sees similar current/voltage as if there was a mechanical chime in place. With just the chime trigger, the resistance is too high, so I'm trying to add a path with less resistance so the power kit sees similar values to a mechanical chime.

The initial setup had the power kit in parallel with the chime trigger (as per wiring a mechanical chime), and after ~10 hours, the doorbells had flickering LED's but were not functional (around 5v at the doorbell) and the chime trigger was quite warm (measured 11v there).

I'm thinking the powerbox malfunctioned because it was seeing more load?

Thanks!
