Nice little alarm,
This review is from: First Alert Photoelectric 10 Year Battery Smoke Alarm,SA700LUK (DIY & Tools)Compact and unobtrusive smoke alarm. The long life battery is a great benefit
if you've owned other models that the battery lasts about 1 year on and then
starts the annoying beep-beep to have it's battery replaced. Fit and forget.
