7. Remove the old backplate
Unscrew the backplate from the electrical
box. Save the screws to install the Nest
backplate later.
6. Remove your old smoke alarm
To prevent electrical shock, make sure the
green power light is off on the alarm. You
may have to twist the alarm to release it.
Carefully remove it to keep from damaging
your ceiling or wall.
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.
Tip: Your old smoke alarm might make a loud noise
when you disconnect it.
