This easy-to-install, UL-listed alarm features advanced technology, a user-friendly design, and backup battery power to provide continual monitoring of carbon monoxide levels. It also comes complete with an "Alarm Action" chart that instructs you on what to do if the alarm sounds.

Carbon Monoxide: The Leading Cause of Accidental Deaths in the U.S.
Carbon monoxide, an invisible, odorless gas, is the leading cause of accidental poisoning deaths in America, yet many people don't know they are suffering from CO poisoning until it's too late. Because you can't see, taste, or smell it, CO can kill you before you even know it's there. Likewise, exposure to low levels over time can make you ill. The Consumer Product Safety Commission recommends that every home have at least one carbon monoxide alarm with an audible warning signal--like the CO605--installed near sleeping areas. An alarm like the CO605 can detect the CO you can't see, smell, or taste before it causes any physical harm to you or your family.

Electrochemical Technology for Accuracy and Longer Life
The CO605 uses an electrochemical carbon monoxide sensor--the most accurate CO sensor available. In comparison to more commonly available technologies, electrochemical technology is highly accurate, requires a lower amount of power, and boasts a longer life. If the CO605's sensor detects a high concentration of CO, the unit will sound a clear, loud, 85-decibel alarm, giving you a chance to either ventilate the area or safely evacuate.

A/C Power with Battery Backup and User-Friendly Design
This unit runs on A/C power, but in case of an electrical outage, it will switch to battery operation. This gives you peace of mind during storms--when you're more likely to use generators that could potentially give off dangerous levels of CO.

For added convenience, installation is a snap. Simply plug the CO605 into any wall outlet--with no additional mounting--and it's ready to go. The unit features two 'AA' batteries to provide backup power to the monitor in the case of power disruption or outage.

Operation is equally trouble free. One button clearly labeled "Test/Silence" lets you test the unit to see if it's running properly or silence it during a false alarm.

Continually Monitors Both CO Levels and Battery Power
To give you real peace of mind, the CO605 continually monitors CO and re-alarms if dangerous levels persist. At the same time, a low-battery signal let's you know when it's time to replace the backup batteries (included); a low-battery mute quiets the signal for up to eight hours. An easy, front-open compartment allows for easy battery changes without dismounting the alarm, and an end-of-life chirp lets you know when it's time to replace the unit.

The CO605 comes with two 'AA' batteries and a five-year limited warranty. It also comes complete with an "Alarm Action" chart that instructs you on what to do if the alarm sounds.

What's in the Box
Carbon monoxide alarm, two 'AA' batteries, and user's manual complete with "Alarm Action" chart.

Provides 10-year sealed lithium battery and digital display. Never Change a Battery. CO Alarm Lasts 10 Years.

Kidde infographic view larger Carbon monoxide alarm in the living room view larger Kidde Worry-Free Digital Carbon Monoxide Alarm Kidde Worry-Free carbon monoxide (CO) alarms offer 10 years of continuous detection from the leading cause of accidental poisoning deaths in America carbon monoxide. The UL-listed alarms are the first and only models to contain a 10-year sensor as well as a sealed-in lithium battery proven to power the alarm for a decade. These two state-of-the-art technologies combine to create a premier level of protection. Digital Display Screen clearly shows the level of CO in that room and updates the reading every 15 seconds. Homeowners have peace of mind knowing their CO alarm is always on, and they never have to be hassled by low-battery chirps or battery replacement. Until now, a CO sensor operated for five to seven years, based on the manufacturer. The Worry-Free alarms last nearly twice as long as the average model.

Long-Life Sealed Lithium Battery: Why It s Needed Each year, fire departments respond to an average of 72,000 CO poisoning incidents, according to the National Fire Protection Association. Known as the silent killer, carbon monoxide is odorless, tasteless and invisible. The only safe way to detect it is with a working CO alarm. Industry surveys find approximately half of U.S. homes have a carbon monoxide alarm installed, most of those are battery-operated. A recent survey conducted on behalf of Kidde found homeowners number one fire safety complaint is a low battery chirp.

Worry Free Benefits The C3010D carbon monoxide detection unit provides one decade of protection; the sealed lithium batter provides 10 years of continuous power. It is also both maintenance-free and hassle-free; never replace a battery during the alarm s operating life and no need to worry about the batteries being removed. Additionally, this Worry Free unit is the longest sensor life available and is proven effective for ten years with quick and easy installation by simply sliding the alarm onto the mounted bracket which activates it automatically. Money savings: no batteries to buy and replace every six months, save up to $40 over the life of the alarm.

What's in the box One single Kidde Worry-Free Digital Carbon Monoxide Alarm. A ten-year limited warranty.
