Kidde i9030 FyreWatch Battery-Operated Smoke Alarm

From the Manufacturer 70-Percent of all home fire deaths occur in homes with no alarms or no working alarms, and nearly one quarter of smoke alarms in reported fires are not working. Battery operated Ionization smoke alarms are designed to help protect you and your family from the dangers of fire. This model is powered by a 9V battery, providing continuous protection, even during power outages. The tamper resist feature makes your smoke alarm somewhat tamper resistant. Install UL listed smoke alarms on every floor of your home, in hallways, inside bedrooms and outside of sleeping areas. Replace smoke alarms every 10 years. Ionization sensing alarms may detect invisible fire particles (associated with fast flaming fires) sooner than Photoelectric alarms. Studies show both types will effectively detect either type of fire. For optimal protection, install both smoke alarm technologies in your home.
