Designed for residential use, the Nighthawk Carbon Monoxide detector keeps everyone in the house safe from poisonous, odorless CO fumes. The unit detects carbon monoxide levels from 30 to 999 parts per million. Its low-profile design doesn't stand out when connect to any wall outlet. The unit plugs directly into AC outlets for easy setup, and comes equipped with a 9-volt battery for backup during power outages. Its loud, 85-decibel alarm is sure to alert the whole house when safe carbon monoxide levels are breached. The Nighthawk is UL listed, and features a continuous digital readout of carbon monoxide levels, as well as peak-level memory display, and a test/reset button. It also can be stationed on a tabletop with the included 8-foot AC cord. The Nighthawk comes with a 5-year manufacturer warranty. --Brian D. Olson

 DO NOT BUY!!!!!! August 17, 2008
Not Been Sleeping
Bought one of these at one of those big box home stores. After about two months of use in a bedroom the thing started going off. Public service found nothing wrong and the other two older detectors were not detecting anything. Took it back and exchanged it and the new one started going off for no reason too. Public service again checked and found nothing, told me they'd had several other similar calls lately. These things are either defective by design or break down easily so if you want to sleep at night DO NOT BUY THIS MODEL!!!!
 Excellent carbon monoxide detector July 7, 2008

We bought this particular detector because they are used where my husband works. He works in a warehouse where propane forklifts run all day, all seasons of the year, and Kidde is the brand they use. They work quite well there, so we figured they should work equally as well in our home. It does. I especially like the ability to place it directly in the electrical outlet or to hang it on the wall above the outlet, or place it on a shelf near an outlet. The battery back-up is another plus, as we sometimes lose power during storms.

I've had one of these for 4 years and it been great. This one is replacing one by a different manufacturer that just went bad.
False Alarms May 31, 2008

This is the third Kidde Nighthawk that we've owned and all have exhibited the same behavior - after a little more than a year they produce a false alarm in the dead of night. How do we know the alarms are false? First, the alarm isn't continuous. The unit sounds long enough to get us out of bed and get our hearts pounding and then stops. Second, the display reads 0 ppm CO. Third, when we check the peak level of CO it is always below the threshold level where CO would be a concern. I have tried replacing the battery even though "LB" is not displayed. The result is the same behavior and frustration a week or two later. Our first two units were the combined CO and explosive gases units which others have noted are problematic. However, we have had the same problem with this unit (CO only). Interestingly, the alarm usually sounds in the summer when we have the AC on, rather than when we are heating the house with natural gas. I'm wondering if others have had this problem.
