Can a wired Nest Protect operation only in battery mode?

Community Member

I have a wired Nest Protect (use 3 batteries) and after I moved to a different place, I find that this new place does not have the wired connection for smoke alarms. So I wonder, can a wired Nest Protect be used purely in battery mode? if so, will it last not as long as the battery version (which I think has six batteries)?

You can use the wire Nest Protect as a battery-only device but it is not recommended and it will drain the batteries real fast.

Hello folks,


I wanted to ensure that everything was covered here.


Thanks for the input, @Patrick_Caezza.


@pasu857, in addition to what was mentioned above, the Wired Protect uses its backup batteries to keep all features up and running. It is designed to have a multiple-year battery life. If you have a consistent source of power, the backup batteries should last the life of the Protect.
