The Kidde KN-COSM-BA Battery-Operated Carbon Monoxide and Smoke Alarm combines two important safety devices into a single unit. This alarm includes a voice warning system that announces “Fire, Carbon Monoxide, Low Battery, or Smart Hush Activation.” The voice alarm eliminates any confusion and clearly warns you and your family of a smoke or carbon monoxide danger, or if your battery is in need of replacement. This unit uses two AA batteries, protecting you and your family even during a power outage.
