Product Description

Product Description

The Kidde Hardwired Carbon Monoxide Detector with 9-Volt Battery Backup, Digital LED Display uses electrochemical sensor technology to detect poisonous CO gas in your home and alert you by sounding an 85-decibel alarm. Setup is easy as the Kidde carbon monoxide alarm plugs into a standard, 120V AC power outlet in your home, while a 9-volt alkaline battery (included) works as a backup in the event of a power failure. When carbon monoxide is detected, the digital display shows the level of carbon monoxide the alarm is sensing and updates every 15 seconds. Peak Level Memory records the last time carbon monoxide was detected or when the unit was tested. 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. 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 manufacturer's warranty. Meets requirements of UL 2034, UL217, NFPA72, (chapter 11 2002 edition) The State of California Fire Marshal, NFPA101 (One and two family dwellings) Federal Housing Authority (FHA), Housing and Urban Development (HUD).

An essential device designed to protect you and your family from the dangers of carbon monoxide in your home, the Kidde KN-COP-IC carbon monoxide alarm can be installed on the surface of any wall or ceiling and hardwired into your home's electrical system. It also offers a digital display that shows the current carbon monoxide (CO) level at a glance as well as a battery backup. With an increasing number of state and local governments passing legislation requiring CO detectors in homes, it's never been a better time to safeguard your family against carbon monoxide exposure.



The hardwired Kidde KN-COP-IC carbon monoxide alarm.


Easily mounts to ceilings or walls, and it provides a digital display and battery backup.

Features

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.

What's in the Box

One Kidde KN-COP-IC hardwire carbon monoxide alarm, one 9-volt battery, one adjustable mounting bracket, and operating and installation instructions.

Nice, but I miss the KN-COPF-i
5 Stars
Nice, but I miss the KN-COPF-i
This is a good Carbon Monoxide detector, but it doesn't look as nice as the obsolete KN-COPF-i that was flush mounted in the wall. After 7 years CO detectors expire and must be replaced. The obsolete model looked more upscale than the new model that is a standard Round design like everything else on the market.I also added one on the wall in the basement utility room with the furnace and water heater.
