Mechanical chime not working when hardwired to 2nd Gen Doorbell

[OA1]

Hi team,

I’ve hardwired the Arlo to my mechanical doorbell as instructions show. The socket wires shows 12V and the instructions manual for Arlo says at least 10V.

I had a certified electrician check this and try to set it up. Didn’t work. He scratched his head after 30min of work.

We tested the wires and the mechanical doorbell chimes as it should with the old doorbell (non-Arlo)

We even tested to touch the wires to the Arlo receivers when not set to the bracket to make sure the bracket was not the issue. No chime. No charge. 

What could be the issue here? Is the Arlo defect?

Thank you for taking the time.

WHile it could be a faulty doorbell, was the voltage tested as AC or DC? Apparently some regions use a DC voltage which won't work.

Also, did you set up the doorbell to use a traditional chime when you installed it?

Thanks.

It’s AC in my country, Sweden.

Yes, if you mean by picking that option in the installation guide.

It sounds like it might be a defective doorbell.

Thanks. I’ll try the warranty.
