Where should I install it?

You can install Nest Protect in the same place as your current smoke alarm. But there are a few things to keep in mind if you’re installing Nest Protect in a new room, moving it to a better spot or adding more alarms to your home. You can see all the details in our User’s Guide.

Local laws may have additional regulations on placement and type of smoke and CO alarms. You should review those as well.

Which Nest Protect should I get?

To figure out if you need the wired or battery version of Nest Protect, just check which kind of smoke alarm you have now, then switch it out for the same type.


If your old smoke alarm isn’t attached to any wires in the ceiling or you want to install Nest Protect in a new place, then grab the box that says Nest Protect (Battery).

Wired 230V

If the smoke or CO alarm you’re replacing has a green LED light and connects to wires in your wall or ceiling, then you need Nest Protect (Wired 230V).

Do they work differently?

Both the wired and battery Nest Protect have the same core features and will connect to one another. There are a few small differences in the way that they report self-monitoring info and connect to the Nest Thermostat.
