From the Manufacturer
The leading cause of accidental poisoning deaths in North America, Carbon Monoxide is odorless, tasteless and invisible. It is a silent killer. Kidde CO alarms include the most accurate sensing technology available, the patented Nighthawk electrochemical sensor. This unit combines a Carbon Monoxide and an Ionization Smoke Alarm, providing two important safety devices in a single unit. This alarm includes a voice warning system that announces "Fire, Carbon Monoxide, Low Battery or Smart Hush Activation." The voice alarm eliminates any confusion and clearly warns you and your family of a smoke or carbon monoxide danger, or if your battery is in need of replacement. This combination alarm is battery operated, protecting you and your family even during a power outage when many incidences occur. Install at least one CO alarm on every floor and in sleeping areas. Make sure CO and Smoke alarms are at least 15 feet away from cooking or heating appliances to prevent false alarms. Replace CO alarms every 5 to 7 years to benefit from the latest technology upgrades. Replace smoke alarms every ten years.

Customer Reviews

Do you like paying for an electrician? Then buy Kidde products.
I've had the Kidde combination smoke and carbon monoxide alarm installed for three years and have paid $300 in electrician bills to install and fix them. Tomorrow morning I will pay again because the things wont stop chirping again.

The chirping is not caused by the battery. All the wire-in units have been reset. This is not the first time this is happened or that the units have alarmed because of a malfunction. Last time the units were still under waranty and Kidde replaced one. (Kidde didn't offer to pay for both visits by electricians.) Tomorrow morning I will pay another electricial but this time to unistall all of the units. I'm going back to the simpler battery-opperated ones (not by Kidde). I will never buy another Kidde product.

Oh, and forget any trouble-shooting help from the manual or the KiddeUs.com site. I found no help for this either place.

Great Value!!!
I originally purchased two of these 7 years ago when I moved into our new home. The two I just purchased are replacing the original two. Being a Firefighter I am very safety minded. Because these are two-in-one alarms, I think they are a super buy. About 4 years ago one of the alarms went off in the middle of the night warning of Carbon Monoxide. My charcoal grill was put back into my garage too soon and CO was building up in the house. THANKS to Kidde and this alarm system!!! Remember to replace these units every 5-7 years and replace the batteries every time the time changes...(every 6 months)

Works , No gimmicks ,
Basic Carbon monoxide detector / fire alarm , works well (went off, when I was running a clean cycle on our stove).
It's got a voice prompt so you really know what has triggered the alarm.
Easy to install.
Has clicker so that you can adjust it to be perfectly horizontal for aesthetic purposes.
