First Alert BRK FG250B Ionization Smoke Alarm – Battery Powered, 9V Included, White

This is a First Alert smoke alarm that's essentially brand new but comes in an open box.

The box might show a little wear from storage, and the unit could have some tiny, barely-there surface marks, but it has never been used or installed.

It's the reliable FG250B model, which uses ionization technology to quickly detect fast-flaming fires.

It runs on a simple 9-volt battery (included!), so you don't need an electrician to get it set up—just pop it on the ceiling or wall.

It's a straightforward, no-frills white alarm from a brand you trust to keep your home and family safe.

A great way to get a top-quality alarm at a great value.
