The Battery Powered Smoke & Carbon Monoxide Voice Alarm (2 AA batteries included), is equipped with self-testing components that are always checking to make sure the alarm is on and working.* This smoke and CO combo alarm helps protect you and your family from 2 dangerous threats - fire and carbon monoxide - in one unit with Voice Warning: Clearly alerts "Fire! Feu!" when a smoke or fire hazard is present, "Warning! Carbon monoxide! Attention! Monoxyde de carbone!" when CO is detected, or "Low battery. Pile faible". What's more, the included mounting bracket makes installation quick and easy. Battery-powered smoke alarms provide reliable detection even during power outages, for extra peace of mind.
