GENERAL MAINTENANCE
CLEANING YOUR NEST PROTECT
Nest Protect has been designed to be as
maintenance free as possible, but you should
keep it clean. As with any smoke alarm,
dust buildup on the outside or inside of Nest
Protect can stop it from working properly.
To clean Nest Protect:
1. Turn off power to Nest Protect at the
breaker box (see p.9)
2. Remove it from the wall or the ceiling (turn
counterclockwise until it comes off the
backplate and detach the power connector).
3. Wipe the outside with a clean, slightly
damp cloth. Don’t use any soaps or solvents.
4. Place Nest Protect on a soft, dry cloth with
the Nest button facing down. Open the
battery compartment door and remove the
batteries. Remove the screws and lift off
the back. Be careful to not lose the screws.
5. Gently vacuum the inside. Make sure
to clean all the way around the mesh
sides of the smoke chamber (the large
metal circle).
Note: Never use detergents or solvents (like
glass cleaner) on your Nest Protect and do
not spray air fresheners, hair spray or other
aerosols near it. Do not get water inside the
alarm or paint over it.
REPLACING THE BACKUP BATTERIES
In case of a power outage, Nest Protect will
use three AA Energizer® Ultimate Lithium
batteries (L91) for backup. These batteries
can be purchased at your local retailer.
1. Turn off power to Nest Protect at the
breaker box (see p.9)
WARNING
• Use only batteries specified by Nest.
Use of a different battery model will
have a detrimental effect on the smoke
alarm operation.
• Never disconnect a wired alarm to stop
an unwanted alarm (caused by cooking
smoke, etc.) Removing power disables the
alarm so it cannot sense smoke or carbon
monoxide (CO). Instead open a window or
fan the smoke away from the unit.
• The batteries cannot work until you install
the batteries in the correct position
(Match + to + and - to -).
• Once Nest Protect has expired you’ll no
longer be protected from smoke or CO if
you don’t replace it.
