Description
Nest Protect GEN2 uses
information from its sensors
to detect smoke or CO in your
home, test itself, light your
way in the dark, and more.
Split-Spectrum Sensor:uses
two different kinds of light
to detect smoke from a wide
range of fires, including
both fast-flaming and slow
smoldering fires, a first for
home smoke and CO alarms.
Carbon monoxide
sensor:detects carbon
monoxide (CO), an odorless,
colorless and potentially
deadly gas. The CO sensor
lasts up to 10 years.
Heat sensor: enables Nest
Protect to detect sudden
rises in temperature.
Humidity sensor: enables
Steam Check. This Nest
Protect exclusive feature
uses an advanced software
algorithm to reduce nuisance
alarms caused by things like
steam from your shower.
Occupancy sensor: detects
when you are walking under
Nest Protect to turn on
Pathlight and light your way
in the dark. And if you have
a Nest Learning Thermostat,
the occupancy sensor also
helps with Home/Away Assist,
so you can save energy while
you're gone.
Ambient light sensor:tells
Nest Protect when you've shut
off the lights for the night
so it can automatically turn
on Nightly Promise and
Pathlight.
Microphone: enables 2nd
generation Nest Protects to
test their speaker and horn
each time you run a test.
This feature is called Sound
Check.
