Tools and Hardware Reviews of Kidde KN-COPP-3 Nighthawk Plug-In Carbon Monoxide Alarm with Battery Backup and Digital Display
Customer Review: HORRIBLE
Summary: 1 Stars
These alarms were in our house when we bought our house, and today one started going off stating low battery. When I unplugged it from the wall to change the batteries, the alarm started going off NON STOP. I could not get the battery incasement to open up, so I had to plug it back in and listen to it beep ALL DAY. If it is unplugged, the alarm goes off continuously. I called the company, and the customer service representative said that since it is more than five years old, I should just throw it away. Way to stand behind your product. She also said you have to be very very strong to remove the batteries. That's an understatement. And she said removing the batteries is the only way to silence the deafening alarm. My ears are hurting very badly, as are my three year old's, and he also has been complaining of a headache since the incident. I wonder if the loud alarm about which the company boasts has caused permanent hearing damage for my child and myself. I only will buy an alarm from now on that has a hush button or switch, so that you can silence it while trying to change the batteries. I think one star is being generous, but Amazon doesn't offer a half of a star.Customer Review: Reliable and Simple to Use
Summary: 5 Stars
Have had this product for about 5 years. You just install the 9-Volt battery and plug it in. I like this model because it actually gives you a digital read-out so you can tell how much CO is in the air. Most importantly Kidde has an excellent reputation for quality.
When CO Detectors first came out on the market, I bought a First Alert CO Detector with no digital readout. Many of the First Alert alarms in Chicago were so sensitive they started beeping just from the CO coming indoors from cars, buses, and trucks. At first the company refused to do anything, but the mayor embarrassed them in press conferences so they agreed to replace the original models with less sensitive models.
Then my alarm (about one year old) beeped. The fire department spent a half hour at my house but could find no CO anywhere. We called First Alert, but they said that they were only replacing CO Detectors for Chicago customers. (We live in the suburbs.) Now I can understand that this brand new product needed some tweaking, but I didn't accept First Alert's refusal to stand behind its product. I have used Kidde ever since and never had a problem.
Customer Review: Works Fine for Me
Summary: 5 Stars
I bought this as a replacement for the same item which reached its 7-year end of life. I was a little hesitant because there are so many reviews with problems with false alarms. My original 7-year-old model worked just fine, never a false alarm.
I waited over 2 months to write my review to see how it would perform which is, just perfectly. I have not had a single false alarm or any problems.
The new models do tell you plainly that they will quit working 7 years after first use. It is on the packaging, it's in the manual, and it's on the device itself.
I recommend to always keep your receipt and if you think you got a lemon, contact Kidde. I really didn't see any better choice in the marketplace.
I can assure you that the false alarms and battery drain that people report have nothing to do with power outages. My previous CO alarm was used in an area that had frequent and sometimes prolonged power outages. Frankly I never even thought to change the battery more frequently than every year and the alarm functioned just fine.
Customer Review: False Alarms
Summary: 1 Stars
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.Customer Review: May have saved my family from a tragedy
Summary: 5 Stars
This device detects low level CO. The reading was dead on the levels measured by our fire department. How do I know? While on a weekend trip with some of my buddies, this thing alerted my wife that there was a leak at home. She called the fire department when both of our meters, upstairs and downstairs, began to sound the alarm. When they arrived, they used a fancy detector with a probe to locate the source of the problem. The exhaust duct from our water heater in the cellar had separated at an elbow, causing the gas to leak outside of the chimney and up through the floor. The fire fighters measured the gas levels around our detectors, and the measurements were consistent, before and after they reconnected the duct. There was never any odor or sign of a problem other than our Kiddie alarms. The level of CO was over 250PPM when the fire department arrived. That is high enough to do serious harm. What a life saver! I now have a total of four detectors, and I sleep better for it.
