Daily Use
Power
Nest Protect (Wired 120V) has a small green light
located at the top of the buon. It will be on as
long as Nest Protect is geing AC power from
the electrical wires.
If there’s a wiring problem or power outage, the
green light will turn o and Nest Protect will switch
to backup baeries. You’ll also see a yellow (instead
of green) Nightly Promise light when you turn o 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 repos
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 aention.
For instance, the baeries are low, Wi-Fi is down,
or there’s an issue with the sensors. Just push the
buon or use the Nest app to see what’s wrong.
Pathlight
Usually Nest Protect has its light turned o, 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.
Emergency Preparation
Testing
Peorm a manual test of your wired Nest Protect
at least weekly. During a test, all interconnected Nest
Protects in your home check their sensors, power,
Wi-Fi connection, light ring, 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. Sta a test by pressing the buon 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.
Sound Check
Nest Protect can automatically peorm a monthly test
to conrm that its speaker and horn are working properly.
You can choose to enable this option during initial setup
with the app, but you can change it at any time. For more
information, visit g.co/nest/soundcheck
