Installation Tips
– Make sure to weather proof the doorbell. Although the unit itself is sealed, preventing water reaching the wire terminals at the back will prevent water from eventually corroding the wires.
– Creating a mini cavity in solid walls using a small section of plastic pipe will help conceal the excess wires inside, so that you can maintain the bell should you require.
Bare wire sticking out. In this instance a networking cable was used. You can even use a 2 core, 4 core or 6 core wire.
A small cavity was created. Then a small section of overflow pipe was inserted to create a small cavity for the wires to be pushed back into. The gaps were then sand cemented. The overflow pipe was sticking out from the wall by approx 2mm so that is could be sealed using mastic for a watertight seal between the backplate and the wall.
Finally after connecting the wires, the Nest Hello Doorbell was clicked into place.
