Advanced Technology Monitors CO Levels in Your Home
The Kidde KN-COB-B 9CO5 battery-operated carbon monoxide alarm utilizes sophisticated electronic components to protect you and your family from the dangers of carbon monoxide. Suitable for all living spaces and featuring a seven-year life, this alarm includes a snap-on cover that gives immediate access to the batteries, and the battery lockout system makes it difficult to close the cover when the batteries aren't installed.

About Carbon Monoxide: The Silent Killer
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.

When placed on every level of your home, alarms like the KN-COB-B can help protect everyone in the house from experiencing prolonged exposure to CO by sounding an unmistakable signal indicating CO levels have reached an unhealthy point.

Continual Monitoring with Flashing LED and Alarm
The KN-COB-B provides continual monitoring of CO levels in your home. Its green LED will flash every 30 seconds to show that the unit is functioning properly. Should it detect elevated CO levels, its red LED will pulse, and a clearly audible alarm pattern will sound until the device is reset or the CO is eliminated.

Reliable Battery Operation
Because the KN-COB-B is battery operated, it provides constant protection--even during power outages--so you'll always have peace of mind. Its battery lockout system prevents incorrect placement of the batteries by not allowing the cover to close unless the batteries are placed correctly, and a snap-open cover makes for easy changes. The KN-COB-B also features a low battery signal so you know exactly when replacements are needed.

Compliancy and Warranty Information
The Kidde KN-COB-B alarm is UL-listed and is backed by a five-year limited warranty.

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 alarm includes a snap on cover that gives immediate access to the batteries and a safety feature that makes it difficult to close the cover without the batteries being installed. Install at least one CO alarm on every floor and in sleeping areas. Make sure CO 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.

False alarm June 19, 2010
Size Name:One Pack
this thing woke us up at 2 in the morning... kept going off so we called the fire department. we sat out on our porch for 2 hours talking to a policeman and fire chief while we waited for the gas company and a sherifs deputy to show up with testing equipment! LOUSY machine!!! they couldn't find any problems, but the gas man said to set it outside in the fresh air to reset. Don't you know, started going off again (outside) while we were trying to catch up on our sleep. We've only had the thing for about 2 months. My husband just put it together and mounted it on the wall a few weeks ago, so it should be in tip top shape!

Better Safe Than Sorry September 17, 2008
Size Name:One Pack|Amazon Verified Purchase
I've used several carbon monoxide alarms from First Alert for the past couple of years. Sadly, I was very dissapointed with the fact that they've shorted out after only a few months. For Kidde, they've made high quality carbon monoxide alarms, but also a very convient prices. The Kidde KN-COBB Basic Carbin Monoxide Alarm is a very simple and easy to setup alarm. This alrm is very affordable, and you can easily hang it up, without any problems. It is also easy to install the batteries, unlike those that require a 9 Volt batteries. Here, all it takes is a trio of AA batteries, and it works better, even during a power outage. Kidde does show it, and I really suggest you have one for your everyday houselhold.
