The First Alert OneLink SCO501CN-3ST Battery Operated Carbon Monoxide and Smoke Alarm not only alerts you to the dangers of smoldering fires or poisonous leaks, but it creates wireless links to all the other alarms in your home for a safety network you can depend on. Using photoelectric technology, this alarm reduces the nuisance of shrill sirens anytime there's steam from the shower or a potent aroma from an overcooked slice of toast. It also comes with 11 pre-programmed choices and a voice location feature that calls out where the hazard is and whether it's CO or fire related. Other features include an end-of-life timer, low battery warning, and a test/silence button. The First Alert SCO501CN-3ST Battery Operated Carbon Monoxide and Smoke Alarm is packaged with 2 AA batteries and is backed by a 7-year limited warranty.
