5. Remove your old smoke alarm
You may have to twist the alarm to release it.
Remove it carefully to avoid damaging your
ceiling or wall. Unscrew and remove the back
plate if there is one.
6. Install the Nest back plate
Screw the Nest back plate directly into
the wall or ceiling with the Nest screws.
There is no need to drill pilot holes, as the
Nest screws are self-tapping.
Tip: Your old smoke alarm might make a loud noise
when you disconnect it.
Tip: All smoke alarms prefer to live in a dust free area,
so remove any dust before you install Nest Protect.
