The Kidde C3010D is a 10-year, sealed battery, carbon monoxide alarm which includes a digital display feature and uses electro-chemical sensing technology to protect you and your family from the dangers of carbon monoxide. The C3010D alarm will automatically activate when it is attached to the mounting bracket. At the end of alarm life, the unit will chirp, indicating the alarm is in need of replacement. A screwdriver can be used to deactivate the unit, stopping the end-of-life chirp and making it safe for disposal. The inside cover of the mounting bracket features a quick reference guide for what to do in case of an alarm. This easy-to-install alarm is suitable for all living areas and has a 10 year life and limited warranty. The Kidde C3010D provides you and your family with a loud warning signal in response to elevated levels of carbon monoxide in your home.  The unit contains a 10-year tamper proof battery that eliminates the need for battery replacement, and provides continuous monitoring of CO levels, even during power outages.  The digital display feature allows for easy viewing of carbon monoxide levels from 30-999 PPM (parts per million). The C3010-D will also detect and store concentration levels as low as 11 and up to 999 PPM with its peak level memory display. The 10 year limited warranty lasts the life of the alarm. The leading cause of accidental poisoning deaths in North America, carbon monoxide (CO) is often referred to as the silent killer because it's odorless, tasteless, and invisible. Carbon monoxide poisoning can come about via a number of sources, including everyday items and appliances in your home or office. And because symptoms of CO poisoning mimic the flu or other common illnesses it can often go undiagnosed. Key Features:
