1. Check compatibility and voltage requirements

While the Nest doorbell can replace most wired doorbells, there are some cases where the doorbell system either doesn’t provide enough power or provides too much power. You should check that your current doorbell can be replaced by the Nest doorbell.

Connect power wires to Nest Doorbell

• Before you connect the wires make sure they are clean.
• Connect the power wires to the wire connectors.
  • It doesn’t matter which connector you attach a wire to.
  • Press down on the release tabs to insert the wires into the connectors.
  • If you see exposed wire, remove the connectors and trim any excess wire.
• Important: Don’t let the connectors touch the backplate. This can cause an electrical short and damage the doorbell. Make sure that they only touch the screws. Tighten the screws to secure the connectors.
• Make sure the wires point down, not up, so the extra wire can be tucked back into the wall.

Without the connectors

• Before you connect the wires to the screws, trim the wires and the insulation so only ¼ inch of wire is exposed.
• Bend the wires clockwise into a hook shape and attach to the screws.
• Important: Don’t let the wires touch the backplate. This can cause an electrical short and damage the doorbell. Make sure that they only touch the screws. Tighten the screws to secure the wires.
• Make sure the wires point down, not up, so the extra wire can be tucked back into the wall.
