To activate your existing chime when the Blink Doorbell button is pressed, you can connect the wires from your doorbell button to the back plate of the Blink Video Doorbell.
The Blink Video Doorbell can close the wire-circuit and activate a digital or mechanical chime when its button is pressed. Amazon Echo devices can be used as a wireless chime and doorbell announce, but we do not interface with wireless doorbell systems.
Mechanical chime systems in North America usually provide 16 to 24 volts AC at 50 - 60 Hz, 40 VA maximum. The Blink Video Doorbell can use this current to stay online, listening for commands.
If your chime system provides less than 16 volts AC, the doorbell enters Event Response and stops listening for commands after 60 seconds. In Event Response, you are not able to start Live View or take thumbnail pictures from the Blink app. To regain these features and improve battery life, connect the Blink video Doorbell to a Sync Module.
How do I find the system voltage of the doorbell chime I already have?
Your doorbell system chime box will have electrical information on a label or sticker. Some chime boxes have this information imprinted on the plastic mold, making it a little more difficult to see.
It is also possible that the electrical information sticker is inside the housing of the chime.
Please do not attempt to open any electrical case or product when electricity is live.
