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.
