When you purchase an Arlo Video Doorbell in Europe, you receive a doorbell transformer in the box. The doorbell transformer is 24V AC and is meant to replace your existing doorbell transformer. This is because many doorbell transformers in Europe are 12V AC, which does not provide enough power for your Arlo Video Doorbell.
The included doorbell transformer must be installed if your existing doorbell transformer is not between 16-24V AC. If you want to check the voltage level of your existing doorbell transformer, visit How do I measure the voltage of my doorbell transformer?.
If your existing doorbell transformer is not between 16-24V AC, you must call a qualified electrician to install the doorbell transformer that came in the box with your Arlo Video Doorbell. We do not recommend that you install the doorbell transformer yourself.
After the doorbell transformer is installed, your existing doorbell chime should no longer be used if it is not rated for 24V AC. If your existing chime was rated for operation with a 12V AC doorbell transformer only, then you must enable bypass mode on your Arlo Power Kit to prevent the doorbell from improperly ringing or damaging your chime.
To enable bypass mode, move the switch on your Arlo Power Kit to Bypass Mode, marked by the “X” on the Power Kit. For more information, visit How do I enable Bypass Mode on my Arlo Video Doorbell?.
After enabling bypass mode, you must turn off the traditional chime setting in the Arlo app.
To turn off the traditional chime setting in the Arlo app:
Because you bypassed your existing doorbell chime, your doorbell won’t create a traditional “ding-dong” ring when your Arlo Video Doorbell is pressed. If you still want to hear an audible ring when someone presses your Arlo Video Doorbell, you can purchase and install an Arlo Chime. To use an Arlo Chime with your Arlo Video Doorbell, you must connect both devices to an Arlo SmartHub or base station.
Alternatively, you can consult an electrician to replace your doorbell chime with a chime that is compatible with your 24V AC doorbell transformer.
Note: You will still receive doorbell calls on your mobile device when someone presses your Arlo Video Doorbell, even if your doorbell chime is bypassed.
