Features

Offering a small, sleek design that's suitable for all living areas, the Nighthawk KN-COPP-B-LP provides you and your family with a loud warning signal against the dangers of elevated carbon monoxide levels. You'll get continuous monitoring of CO levels, even during power outages when AC-only units are not providing protection. The digital display adds an advanced level of protection, showing CO levels in PPM (parts per million) and allowing you to see if levels change. The backlighting helps you read the display in the dark, and it also appears during the peak level cycle. The unit also has a peak level memory, which displays the highest CO concentration measured since the last reset.

It features two color LEDs for at-a-glance status updates. The green LED flashes once every 30 seconds to indicate the alarm is working properly. A red LED will pulse to indicate that carbon monoxide has been detected. When the unit detects carbon monoxide, the alarm sounds four short beeps (rated at 85 decibels at 10 feet), followed by five seconds of silence, and then followed by another set of four short beeps. The unit measures 3 inches by 5 inches by 1.5 inches.

The KN-COPP-B-LP includes multiple mounting options, allowing installation on a wall or a tabletop. It has a seven-year operating life (with matching seven-year limited warranty), providing 40 percent longer protection than other CO alarms. It's powered by 3 AA batteries (included).

What's in the Box

One Kidde Nighthawk KN-COPP-B-LP battery-operated carbon monoxide, three AA batteries, and operating instructions.

We bought this CO Alarm after we had a CO incident. Our neighbor is a fire fighter and recommended a unit with a digital display.

This unit was out of the box and in use in about 5 minutes.

All Kidde CO Alarms are UL Listed and other brands are not. Google "UL Listing" to find out more about this established testing lab. Some states mandate consumers have UL Listed smoke and CO Alarms. Retailers can sell non-UL Listed products so watch your state codes or you may be liable.

This device was very easy to mount, however it did not come with any screws, not sure if that is normal. The alarm seems loud enough to wake you when placed in a hallway outside of the bedroom. I wish that these items displayed all levels (even below 30 ppm) however no detector that is UL rated will have that feature as it is part of the UL specifications that they have to display 0 until the level is over 30. You can still see what it has detected below 30 by pressing the button to see the highest recorded level.

I needed one, now I have one, and I can sleep at night knowing that if something is wrong this thing will let me know.

I now have a second one of these detectors that I placed on the lower floor of my home. I am still happy with this detector, however I do want to confirm what others have posted in this thread that you do get some rather "random" readings from this unit for "highest recorded level" ...

It seems that this number will change each time you run a test, so currently my upstairs unit reads 16, and the downstairs unit reads 20. If I run a test on these units, they will read something else. I do not believe that these are true readings, and I am not sure how this number is generated, thinking maybe it is left over from the test sequence since the test actually does make the circuits inside the unit are tricked into believe that they are seeing levels during the test?

According to the UL spec that these are built with, they are not supposed to read anything until 30ppm is detected, the mfg.

My gas furnace is over 20 years old. Still works fine but I was advised to make sure I had CO monitors. My furnace guy specifically recommended Nighthawk as the most accurate.He said they were more expensive but much more reliable and estimated cost at $40-$70. I looked at a couple of the "big box" stores and he was right. I typically hear about things other places, great recommendations and reviews on TV shpows, magazines etc. and then I check the price at Amazon. 98% of the time Amazon has a significantly better price plus lots more info and feedback that allows me to make an informed decision. Same here...this product was well reviewed and price could not be matched anywhere else. East setup for this product, loud but not annoying alarm, digital readout that I just glance at to know we're A-OK. Like the title says "Peace of mind".

1) Detection: 70PPM = 60-240min, 150PPM = 10-50min, 400PPM = 4-15 min. The detection on this unit has accuracy of +/-30% in ideal conditions so don't falsely believe you're getting precision measurement ever. (Not that this unit is not particulary inaccurate compared to others, it's just the way CO detection goes in such units). You should know that as low as 30PPM are apparently harmful for kids/elderly, but there's a reason why this unit isn't that sensitive. This is a UL cert unit. UL certified units won't bark at less than 30PPM because of sensitivity/false alarms standards. That means it's not overly sensitive and simply good for healthy adults.

2) Competition: Only one other option really exists. First Alert, same price & features: First Alert CO410 Battery Powered Carbon Monoxide Alarm with Digital Display It's reviewed poorly and not really a valid choice at this point (early 2012) due to quality/bugs. If this is the feature set you want, go with the Kidde no contest. Nighthawk line also have a good reputation and good consumer reports reviews. (Don't rule out First Alert for smoke detectors though... they have some good models there.)

3) You'll actually receive model "KN-COPP-B-LP", not "KN-COPP-B-LS". That's because the LP (long life) replaced the LS (no longer made). Some reviews complain about the subtle differences, and I notice the amazon page still has references to the LS model in product description and product specification sections.

4) Mounting: Saw a review saying it should be mounted low. This is incorrect. Manual advises "eye-level" as optimum, and table top as an option. Carbon Monoxide/CO is slightly lighter than air, but mixes well..

I just had PG&E come in to do a complete carbon monoxide inspection since my oven was giving off lots of CO. The inspector came in with a top-of-the-line industrial CO detector. After tuning the oven, we ran some benchmarks. So, after the oven is turned on for several minutes, the ambient reading came up to 17 ppm. In the flue, it was over 200 ppm. We had to go outside until the reading would go back to zero. We ran several more tests, and all came back 17 ppm ambient with the windows closed, etc... The Kidde Nighthawk, however, read zero. Which is to be expected. HOWEVER, when I did a reset on the unit and then checked the peak level, it would always show some random level of 25 to 27. It even does this when I go outside to the street and reset the monitor. I've read other people on here have noticed the same thing. To the credit of the Nighthawk, it did register readings above 30 ppm in my kitchen before the PG&E inspector tuned the oven. Was it accurate? I can't actually say. Although, Consumer Reports have done a lot of tests with it and found it reliable and accurate. So, who knows? What I do know is that for peak level testing below 30 ppm, it is DEFINITELY not accurate at all. And that's the biggest concern for me. My wife and I have been exposed to low levels of CO for the past 3 years. Anything above 10 ppm is too much, and according to the PG&E guy, even sustained 17 ppm is not good.

You guys should do more research into this stuff before buying. I'm now shopping around for a CO that can detect low levels of CO.
