Placement on the ceiling or wall
Installing on the ceiling is recommended.
Mark where the screws will go using the
base as a guide. Make sure it’s at least
4 inches (10 cm) away from the wall.
Placement on a sloped ceiling
If you have a sloped, peaked or cathedral
ceiling, Nest Protect should be 4 inches to
3 feet (10 cm – 1 m) from the highest point.
9. Attach the Nest connector
Hold the white wire ends together, cap them
with a wire nut and twist clockwise until it’s
secure. Do the same with the black wires.
There’s no need for the red/orange/yellow
wire. Simply cap it with a wire nut and twist
until secure.
8. Remove the old connector
Unscrew the wire nuts to detach the 120V
connector from your old smoke alarm.
