Kidde 10 Year Worry-Free Sealed Battery Smoke Detector with Intelligent and Wire-Free Voice Interconnect (4-Pack)

This Kidde 10-Year Worry Free Battery Wireless Smoke Alarm features voice alert and wireless interconnectivity. Powered by a 10-year battery that lasts the life of the alarm, no battery installation or replacement is necessary. An "end of life" warning will alert you when it is time to replace the entire unit. The voice alarm announces "Fire" if a hazard is detected and indicates when the Smart Hush feature has been activated. This alarm features wire-free interconnectivity with other Kidde 10-Year Wire-Free Interconnect alarms. If one unit is triggered, all interconnected alarms will sound. Wire-free interconnectivity allows for easy interconnect setup and eliminates the need for expensive rewiring. You can even install this smoke detector in a detached garage or workshop and be alerted by another detector in the house. This alarm is also compatible with the Kidde Smart Bridge app and hub (not included), which will send a message to your smart phone, tablet or PC alerting you to a potential threat.
