Advanced Technology in an Easy-to-Install, Plug-In Design
Designed for home use, the Kidde KN-COPP-3 Nighthawk is a UL-listed, A/C-powered, plug-in CO alarm that utilizes sophisticated electronic components and sensor technology to protect you and your family from the dangers of CO. It plugs directly into a standard A/C outlet and includes a 9-volt battery backup that provides continuous monitoring of CO levels--even during power outages.

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.

Audible Alarm Pattern Alerts you to Elevated CO Levels
When placed on every level of your home, alarms like the KN-COPP-3 Nighthawk can help protect everyone in the house from CO exposure by giving you an unmistakable signal when levels have reached an unhealthy point. If unhealthy levels are detected, the alarm will emit four quick audible beats every five seconds until either levels decrease or the reset button is pressed.

Easy-to-Read Digital Display Shows CO Levels
The KN-COPP-3 Nighthawk is unique among traditional CO alarms because of its digital display. This display clearly shows levels of CO that the unit has detected and stored-- from 30 to 999 ppm--and it updates every 15 seconds to indicate any abrupt changes or alarming trends. The display also shows the peak CO level recorded by the alarm since it was last reset or unplugged.

LED Shows Sensor Status
With the KN-COPP-3 Nighthawk, you never have to wonder if the sensor is functioning properly. A blinking dot in the lower right-hand corner of the display denotes normal operation, so you can trust that it's working. In addition, you can test alarm function by pressing the test/reset button at any time to verify that the horn and electric circuitry are operating properly.

Convenient Mounting Options
The KN-COPP-3 Nighthawk has a low-profile design that makes it suitable for any room in your home. The detector can be plugged into any standard A/C outlet; it's plug can be snapped into the back of the unit and can be rotated so the alarm remains vertical, independent of whether the electrical socket is mounted vertically or horizontally. In addition, the alarm comes with a 6-foot extension cord, so the unit can be plugged into the wall outlet and then placed on a table or shelf. For the most thorough protection, place an alarm on every level of your home.

The UL-listed Kidde KN-COPP-3 Nighthawk has a seven-year life and is backed by a five-year limited warranty.

Word of warning! We purchased 3 of these units from Amazon a year ago, and one failed recently. (The digital display showed an "err" message, which indicates the unit is not working, often because it has reached the end of its life.) The unit has a 5 year warranty and 5 year expected use life, so I called Kidde customer support. Their representative was very helpful and asked me to check the date of manufacture on the back of the unit. I did, and was dismayed to find a unit I purchased from Amazon in Oct. 2011 was manufactured in Feb. 2005! It was therefore way past it's expected use period - and out of warranty.

Kudos to Kidde customer support. Even though the unit was out of warranty, and the company was therefore not legally responsible for the problem, their rep. asked if I had the purchase receipt. When I said "yes" she said they would send me a replacement unit. She also commented they have had problems with Amazon shipping such items that were already past their 5 year service life when they were sold.

We buy a lot of items from Amazon, so this was disappointing news. Although I can't confirm if the sale of "expired" merchandise is the fault of Amazon or their supplier, this was a lesson learned. Two of the three such units we bought from Amazon were current products. If you buy one of these units from Amazon (or elsewhere) my advice would be the check the sticker on the back of the unit as soon as you receive it, and verify that the manufacture date is reasonably current.

One reviewer questioned if these really work... YES they do! I had a new furnace installed recently, and the installers made a mistake. Without detectors in the house I might never have known, and my family could have suffered greatly (ie somebody could have become ill or even died!).
We had had them for years and they ALWAYS read 0. When we started seeing it detect CO we knew we had a problem. Occasional low readings (such as near your kitchen on Thanksgiving if you have a gas stove) are ok, but any consistant reading is cause for real concern particularly if it is away from any known source of CO (stove, fireplace, etc).
I strongly reccomend folks place a detector on each occupied level of your home. If something happens you may very well get different readings on different levels (I did).
When selecting a CO detector be sure to pick an electornic one with a digital readout. They cost more, but are well worth it. The only maintenance with a unit like this one is replacing the backup battery. (BTW, a backup battery is a really good idea. Each year many folks die because they used various types of gas heating devices during power outages with inadequate ventalation.) Also, the digital readout will help track down problems envolving lower levels of CO and may give you earlier warning of a malfunctioning heating system.
Finally, this particular unit has an advantage in that it can be placed directly over an outlet, or the included power cord can be used to allow higher wall mounting or placement on a table/shelf/etc.

I also had a problem with my two detectors using up the batteries in one to two months time. But I called Kidde customer service and after I gave them the model no and assembly dates from the back of the units, they confirmed that these models were defective. Apparently there is a faulty circuit that triggers the low battery indicator prematurely. So the batteries are actually not worn down completely. The problem is with the sensor that reads the battery levels. Kidde sent me two new detectors. They are working fine so far. I will know more after a couple months. If you have this problem, call Kidde customer service and they should take care of you.

This alarm seems to be everything it claims to be. Initially plugged it in my garage until I brought it inside. The alarm went off when the garage door was closed too soon after our car was pulled out. I bought this before I read a great review on this product in Consumers Reports. This is a great product

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.

This is probably the best CO detector on the market. It will last you 7 years - the cheaper non-digital detectors will only last 2 years and will end up costing you much more money in the long run.

The best feature is the peak level dectector which will allow you to monitor carbon monixide levels as low as 11 ppm (the alarm will go off if ppms excede 50). There are some reports and studies that show that a constant exposure to low level carbon monoxide gas can cause long term health problems - so this is a handy way to check different parts of your house for this.

I am suprised at the Amazon price for this. I got this at Home Depot in West Roxbury MA for $49.00.
