The Kidde Smoke & Carbon Monoxide Detector, Hardwired with Lithium Battery Backup, Interconnect Combination Smoke & CO Alarm with Voice Alert, model P4010ACSCO-W, is an AC-wired alarm that operates on a wired, 120VAC power source with a sealed, lithium battery backup. Using photoelectric sensor technology, the wired smoke alarm detects visible fire particles associated with smoldering fires. The combination CO detector provides continuous protection from poisonous carbon monoxide, even during power outages. A red LED will flash & be accompanied by 3 long alarm beeps followed by a verbal warning that warns of fire, carbon monoxide, & low battery. The Hush feature silences the fire alarm for approximately 9 minutes.

With 18 initiating devices (smoke, heat, CO, etc.), interconnected, it is still possible to interconnect 6 strobe lights and or relay modules. UL Certified with a 10-year limited warranty.
