(2 pack) Knox Safety Battery Operated Carbon Monoxide Detector, Voice Alert & Display, 10-Year Lithium Power

When seconds count, you need an alarm that notifies you of the present danger and gives you clear instructions on what to do next. The Knox Safety Carbon Monoxide (CO) Alarm with the TRIO Warning System informs you of the current CO danger levels in your home. The alarm alerts you with visual icons, scrolling LED text, and a verbal message on what the CO danger is and what to do next. The alarm's visual and verbal alerts can be set to English or Spanish and include a 10-year sealed battery and product warranty. This is the only alarm that features the TRIO Warning System - which alerts, informs, and directs you in an emergency. Instead of just the standard beeping, Knox Safety carbon monoxide alarms feature over 20 voice alerts that provide detailed information about the current threat and instructions on what to do in the event of an emergency. When combined with our intelligent display, which uses easy-to-read icons and scrolling messaging, the Knox Safety alarms provide you with a superior home safety solution. This is the only multi-language carbon monoxide detector - with alerts available in either English or Spanish. Visual and verbal alerts can be set to English or Spanish. The CO Alarm's three buttons provide important information, including the most recent carbon monoxide level, testing, and a silence option for use with non-life-threatening alerts. Messages can be repeated and when needed, a notification will be provided when the alarm needs replacing. Knox Safety alarms feature a sealed-in battery, which never needs to be replaced and will provide power to the alarm for its entire 10-year life. The lifetime product warranty means that Knox Safety stands behind the product.
