Kidde Wire-Free Interconnect Smoke & Carbon Monoxide Alarm - 10-Year Sealed Lithium Battery, P4010DCSCO-W

Safety upgrade time! This Kidde combo alarm detects both smoke AND deadly carbon monoxide. The biggest feature? It's WIRE-FREE INTERCONNECT. That means you can link multiple Kidde P4010 alarms together around your house without running any new wires. If one alarm goes off, they all sound, giving you more warning no matter where you are. It has a sealed-in 10-year lithium battery, so you never have to change a battery for a decade. No more late-night low-battery chirps! It also talks to you with clear voice alerts ('Fire!', 'Replace Alarm') and has a colored LED ring to show its status. Perfect for updating older homes to modern safety standards without the hassle and cost of rewiring. Remember, it only interconnects with other Kidde P4010 wire-free models. A smart, hassle-free investment for your family's safety.
