Description
The Kidde Smoke & Carbon Monoxide Detector with Voice Alerts, Battery Powered, Combination Smoke & CO Alarm, model KN-COSM-BA, provides two fire safety detectors in one unit through the use of ionization sensing technology that senses invisible fire particles, while an electrochemical sensor detects carbon monoxide. When a smoke, fire, or carbon monoxide event occurs, the Kidde fire alarm warns with an 85-decibel alarm sound, flashing LEDs, and voice alerts. For smoke detection, the alarm will sound with the announcement, "Fire! Fire!" and a red LED will flash in unison with the voice alarm. For carbon monoxide detection, the alarm will sound with the announcement "Warning! Carbon Monoxide!". In the event of a low battery, the detector will announce, "Low Battery!" The Kidde combination smoke and carbon monoxide alarm is powered by 2-AA batteries, which provide coverage during a power failure. A convenient pop-up, front-door battery compartment allows for quick installation or replacement of a battery without having to disconnect the entire unit from the ceiling. In the case of nuisance or false alarm, the Smart Hush button silences the unit for approximately 8 minutes, which is helpful when this smoke detector carbon monoxide detector combo sounds from things like routine cooking or shower steam. When installed, the green LED on the alarm will flash every 60 seconds in standby condition, letting you know that the unit has power & is operating correctly. Install a carbon monoxide smoke detector combo on every level of your home and near bedrooms to help keep your family safe. UL Certified with a 10-year limited manufacturers' warranty.
