Doorbell upgrade
 

I have a wired doorbell with two chimes wired in parallel and I am
thinking of replacing the bell press with a Ring Video Doorbell Pro.
Being designed in the US, this runs at 24v.To enable it to be
installed in UK 12v installations Ring provide a link wire to be
installed in the chime, to disable it. Details he

Two questions:
1) What would be the likely effect of my 12v chimes receiving 24v?
2) Wouldn't it be possible to put a resistor in the circuit so the
chimes get 12v? (I guess that if the answer was yes the Ring would
provide one but I'd be interested in knowing what the team thinks.)

TIA

Is the "Pro" much different from the normal one?

if it's mechanical it won't care much. If electronic it may die.
A resistor dropper can be used, you may often need a big capacitor too to even out the reuslting voltage. Don't overlook how much heat the R produces.

I wonder which bit of the system contains all the intelligence?

If it's the door push box with the camera that contains the wi-fi
transmitter/controller and the plug in ringer is just that then to
obtain your own system just go along to someone with one of these
systems and unscrew the bell push/camera from the front door!

Well Ring is now an Amazon company, but no you could not use a resistor as
the drop over that would depend on current drawn through it. Did you miss
ohms law?
You could use a series regulator chip but in both cases the current drawn
would be greater than if it was in fact matched internally, which I'd have
though was what Ring do in their circuit.
I don't understand why anything should have a different dc voltage in one
country to another though.

Remember however you regulate the voltage, as you take current the extra
dissipation is expressed as heat unless you use a switch mode device where
its the duty cycle that changes. Brian

If the two are the same and just electro-mechanical rather than
electronic, then adapting them to series connection should be OK - If I
understand the question?

This is 24V AC and NOT 24V DC

I don't understand why anything should have a different dc voltage in
one country to another though.


Very short sighted to design a power supply for the push button box that
couldn't supply the necessary internal DC voltages from the electronics
from both 12 and 24V AC. There cannot be anything in the push button
box that in other applications would be supplied from a 5V USB connection.

Don't know. The push is narrower. I'll look at the video later. Thanks
for the link.

It was a long time ago, which is why I asked the question.

would be greater than if it was in fact matched internally, which I'd have

Well, I think I understand the answer. They are both electo-mechanical
- either side of the same spot on a wall as it happens, so I could do
that quite easily.

he finally gives us the relevant info.

Keep everything as is, but use a relay fed from the video doorbell to
trigger the old system?
