Kidde Hardwire CO Alarm

The AC wire-in Kidde KN-COP-IC carbon monoxide alarm offers multiple contractor-friendly features to ensure easy installation and minimal troubleshooting. It can be installed on any standard single gang electrical box (up to a 4-inch octagon junction box), and it features a snap-on electrical harness for quick installation and an adjustable mounting bracket for perfect alignment. The unit also includes a smart interconnect system with up to 24 Kidde devices, including smoke alarms. When interconnected, it can sound its carbon monoxide alarm pattern as well as sound a different alarm pattern when a Kidde smoke alarm is in alarm mode. * It features three color LEDs for at-a-glance status updates. * A green LED lights constantly when AC power is present, and it flashes every 7 seconds when in battery mode. * An amber LED illuminates during a CO incident, while a red LED flashes in unison with the audible alert for both a smoke or CO incident. * A digital display allows constant monitoring of carbon monoxide levels and updates every 15 seconds to let you know if levels change. * The peak level memory feature displays the highest CO level measured since the last reset. * A battery-backup system (powered by included 9-volt battery) provides continuous monitoring of carbon monoxide levels even during a power failure. * It has a seven-year operating life and is backed by a five-year limited warranty.
