WARNING
• DO NOT stand close to the alarm when
the horn is sounding. Exposure at close
range may be harmful to your hearing.
When testing, step away before the
horn starts sounding.
• If the alarm ever fails to test correctly,
have it replaced immediately! If the alarm
is not working properly, it cannot alert you
to a problem.
• DO NOT use a match, cigarette or any other
makeshift fire to test the smoke alarm.
• To test the CO alarm, NEVER use vehicle
exhaust! Exhaust may cause permanent
damage and will void your warranty.
• NEVER use an open flame of any kind
to test this alarm. You might accidentally
damage or set fire to the unit or to
your home.

DAILY USE
POWER
Nest Protect (Wired 120V) has a small green light
located at the top of the Nest button. It will be on
as long as Nest Protect is getting AC power from
the electrical wires.
If there’s a wiring problem or power outage, the
green light will turn off and Nest Protect will
switch to backup batteries. You’ll also see a
yellow (instead of green) Nightly Promise light
when you turn off the lights for the night.
NIGHTLY PROMISE
Nest Protect continuously tests itself, so
you don’t have to wonder if it’s working.
Nightly Promise reports on every Nest Protect
in your home.
When you turn out the lights for the night,
Nest Protect will glow green for a moment - that
means everything is working. If it glows yellow,
one of the Nest Protects in your home needs
your attention. For instance, the batteries are
low, Wi-Fi is down, or there’s an issue with the
sensors. Just push the Nest button or use the
Nest app to see what’s wrong.
PATHLIGHT
Usually Nest Protect has its light turned off, but
it can light your way as you walk underneath it
in the dark. You can enable or disable Pathlight
and set its brightness with the Nest app. Nest
Protect (Wired 120V) also allows you to set
Pathlight to “Always On” if you want a night light.
It will turn on when it’s dark and stay on until it’s
light again.
DAILY USE AND EMERGENCY PREPARATION
EMERGENCY PREPARATION
TESTING
Perform a manual test of your wired Nest
Protect at least monthly. During a test, all
interconnected Nest Protects in your home
check their sensors, power, Wi-Fi connection,
emergency horn, speaker and microphone.
When you run a test, Nest Protect will give you
a countdown before sounding the alarm so you
have time to move away from the loud noise.
Test procedure:
1. Start a test by pressing the Nest button twice.
2. Nest Protect will say: “This is only a test.
The alarm will sound.”
3. Ensure that the alarm sounds and the light
illuminates on each Nest Protect.
4. Once the Nest Protect has made sure it’s
working, it’ll tell you everything’s okay. If you
have interconnected Nest Protects, all of
them should speak.
