Overview
Fast, actionable alerts protect occupants and property with the Kidde Residential KN-COSM-XRT-BA intelligent smoke & carbon monoxide alarm. This combined Smoke & CO detector provides dual-hazard protection—using an ionization smoke sensor for fast-flaming fires and an electrochemical CO sensor for deadly carbon monoxide—while a built-in voice alarm clearly announces the hazard to accelerate correct responses. The two sensing chambers communicate in real time to adjust sensitivity, significantly reducing nuisance alarms and improving overall detection performance.
Designed for practical residential security and monitoring, the unit runs on two AA batteries and includes a Battery Safeguard to prevent misinstallation and maintain protection during outages. Status LEDs, a Test/Reset button, Hush® functionality and low-battery voice notifications simplify maintenance and daily monitoring. UL-listed performance and audible voice prompts make this Kidde Residential alarm ideal for bedrooms, hallways and living spaces where clear surveillance and life-safety alerts matter most.
