ALARM LIMITATIONS
LIMITATIONS OF SMOKE ALARMS
Alarms reduce deaths resulting from home fires
worldwide. However smoke alarms can only
work if they are properly located, installed and
maintained, and if smoke reaches the alarms.
• Smoke alarms may not waken all individuals.
Make sure you create an escape plan and you
practice fire drills with all members of the family.
• Smoke alarms cannot work without power. If
they are powered by batteries, the smoke alarms
cannot work if the batteries are missing, dead
or disconnected. If they are wired, the smoke
alarms cannot work during a long power outage
and once the back up battery is dead. Nest
Protect will warn you in advance when batteries
are running low so that you can replace them.
• Smoke will not be able to reach smoke sensor
while the dust cover is in place. The dust cover
must be removed.
• Smoke alarms cannot detect res if the smoke
does not reach the alarms. For example, if a door
is closed, smoke may not reach the smoke
alarm. This is why you should have a smoke
alarm in each bedroom and in the hallways as
bedroom doors may be closed at night.
• Smoke alarms may not be heard. Although
the smoke alarm comes with a loud horn of
85 decibels, it may not be heard if : 1) people
have consumed alcohol or drugs, 2) the alarm
is drowned by noise from stereo, TV, traffic, air
conditioner or other appliances, 3) residents are
hearing impaired or have high frequency hearing
loss associated with aging. Special smoke
alarms should be installed for those who are
hearing impaired.

after the date of manufacture with a brand new
Nest Protect. Check the date of replacement
written on the back of Nest Protect.
WARNING
You’ll no longer be protected from smoke or
CO if you don’t replace your Nest Protect.
About two weeks before it expires, Nest Protect
will light up with a rotating yellow light. Wave at

recycle the expired one. Make sure you test your
new Nest Protect once it’s installed.
