interference can be overcome by adding more
Nest Protects that can route wireless signals
around obstructions.
WIRELESS INTERCONNECT
Nest Protects connect wirelessly to each other
so that when one speaks, they all speak. That
means when one Nest Protect raises any kind
of alert, every Nest Protect in the house will
tell you which room the smoke or CO is in. For
example, if you’re in the bedroom and the alarm
goes off in the basement, the Nest Protect in
the bedroom will tell you where the smoke or
CO is. To silence the alert, go to the room where
the alarm was triggered. All of the Nest Protects
in the house can be hushed from there. Either
press the button on the Nest Protect or use the
Nest app to hush the alarm.
Nest Protect - Battery (model numbers 05A
and 06A) and Nest Protect - Wired 120V (model
numbers 05C and 06C) are compatible and can
be interconnected wirelessly. Nest Protect
wireless interconnect will not work with other
smoke or CO alarms from other brands.
Nest Protect’s 120V connector does not have
a red/orange/yellow wire for interconnect
because it connects wirelessly. There’s no need
to connect any Nest Protect wire to the red/
orange/yellow interconnect wire coming from
the ceiling or wall.
Nest Protects can typically communicate with
each other if they’re 50 feet (15 m) or less apart
inside a home. Some features of a home may
reduce Nest Protect’s wireless interconnect
range, including the number of floors, number
and size of rooms, furniture, type of building
materials, suspended ceilings, ductwork, large
metal appliances and metal studs. This kind of

• The range and proper operation of any
wireless device will vary depending on
its surroundings.
• Nest Protect alarms are not to be used
outdoors or to transmit between buildings.
The alarms will not communicate properly
in those conditions.
