Replacing the backup baeries
In case of a power outage, Nest Protect will use
three AA Energizer® Ultimate Lithium baeries (L91)
for backup. These baeries can be purchased at
your local retailer.
1. Turn o power to Nest Protect at the breaker
box (see p.9)
2. Twist Nest Protect counterclockwise until
it disconnects from the backplate.
3. Detach the power connector
from the back of Nest Protect
and open the baery door.
4. Replace the baeries. Align
the + positive and - negative
ends with the markings in the
baery compament.
5. Close the baery
compament. Do not force the door closed.
6. Reaach the power connector.
7. Push Nest Protect onto the backplate and turn
it clockwise until you feel it grip.
8. Turn power to Nest Protect back on at the
breaker box.
9. Press the buon twice.

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. Remove it from the wall or the ceiling (turn
counterclockwise until it comes o the backplate).
2. Wipe the outside with a clean, slightly damp cloth.
Don’t use any soaps or solvents.
3. Place Nest Protect on a so, dry cloth with the buon
facing down. Open the baery compament door
and remove the baeries. Remove the screws and li
o the back. Be careful to not lose the screws.
4. 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.
