New 10-year First Alert Smoke Alarm (Forest Hills near Union Tpk)

Brand new First Alert model SM210 with 10-year sealed battery. Giving away because I activated it before realizing I’d bought the wrong model - it’s not also a CO detector. That was only a few days ago so it’ll still be good for 10 years. Tested and works fine, can be reinstalled anywhere. Includes mounting bracket & hardware (which I didn’t use), and the user manual.
