Nest Hello transformer/chime.

[Johnny Thunder]

Afternoon everyone.
A customer has just purchased this video doorbell and asked me to fit to the existing chime, but It appears to be incompatible.
I only have mains and push button connections. There is no access to the transformer terminals.

Does anyone know of an all in one transformer/chime that is compatible to avoid having a transformer mounted next to a separate chime unit?

Cheers everyone.

Is the chime battery or mains/transformer powered?

 

[Johnny Thunder]

Mains powered.

240/220 or from a tranny, the Nest should come with a chime connector.

 

[Johnny Thunder]

I only have two terminals available. These are the push button terminals. There is no access to the transformer connections.

What make and model do you have currently?

 

[Squid]

Nest needs 12/24V to work believe.

What about this

From memory i think 16v is minimum

 

[Johnny Thunder]

Currently installed is a Deta c3500. This is an all in one unit. I really need a similar, but compatible product or I will end up with a din rail transformer mounted next to the chime.

I think that unit pushes out 14V

I used the BG transformer from screwfix and mounted it remotely in a box and fitted a DIN rail. I couldn’t find anything else that would push enough voltage out

Is the door bell fed at the CU or off the lights?
If fed from the CU is there space for the din rail transformer in there?
You could then fit a door bell without a built in transformer.

Or could use alexa echo

These things are designed for the American market where a standard doorbell transformer outputs 16V.

Would a CSU be able to accommodate a DIN style tranny?

 

[Loki]

From the reviews on screwfix they say they fitted them inside the CU, just make sure you have the space

Thanks everyone. Supply is not from the CU.
Going down the route of New enclosure next to the wall chime.
Customer didn't want this , hence me asking if anyone had experience of a compatible all in one unit.

Excuse my ignorance but why has the new enclosure got to be fitted next to the chime? Can't you mount it away from it and just feed the output from the transformer to the chime? You have to run a mains cable to the enclosure and the output to the chime anyway.
