Tools and Hardware Reviews of Kidde KN-COPP-3 Nighthawk Plug-In Carbon Monoxide Alarm with Battery Backup and Digital Display
Customer Review: DO NOT BUY!!!!!!
Summary: 1 Stars
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!!!!Customer Review: Dead after 4 years
Summary: 1 Stars
Unit shows "ERR" which customer service says need to be replaced. Warranty is 5 years. I don't have my receipt from Costco. Bought in 2002.
They won't replace without receipt. Won't ever be buying any Kidde products from know on. Reputable company would have replaced.
Customer Review: Digital readout & peak level memory are very useful
Summary: 5 Stars
Because it has a numeric read-out and peak level memory, you can get a very good idea where and why you have the beginnings of a carbon monoxide problem. Insist on these two features.
Because it's a plug-in 110 volt model, you save on batteries. (9v backup battery will last for years, I hope.)
The manual is pretty good...includes useful tips & guidelines.
I found no problems or flaws.
Customer Review: Does it work?
Summary: 4 Stars
I've owned this for a few months now, but I haven't seen it beep or go off once. I didn't intentionally try to put it near a source of CO2, but the device seems awfully quiet--which is a good thing. It's easy to install. Just pop in the included backup battery and plug it in to an outlet. It seems over-priced 'tho and cheaper models should probably accomplish the same thing.Customer Review: Does not alert the household immediately
Summary: 1 Stars
Kidde -
KN-COPP-3
NOTE: We plan on posting a video of us testing this device in the near future. Concerns with doing so are bandwidth. The video will need to be atleast sixty minutes (60-mins) long. If you have the bandwidth and would like to help by hosting this video, please note your intentions in a comment.
Here is a review of this product that may have some of you thinking long and hard about not only life saving equipment but humanity in general. I spoke with a Kidde technician about; at what reading on the KN-COPP-3 will the alarm sound? The technician I spoke with confirmed what the manual packaged with the unit stated. Alarm will sound as follows:
70 PPM = will sound alarm between 60 - 240 minutes
150 PPM = will sound alarm between 10 - 50 minutes
400 PPM = will sound alarm between 04 - 15 minutes
After reviewing the above with the tech, our next question was in regard to the elderly and people with respiratory issue(s)/concerns; what CO alarm does Kidde manufacture that will alert or sound the audible alarm without delay? The response:
" Kidde doesn't have an alarm that can do the above (sound the alarm immediately upon detection of Carbon Monoxide); a device such as that are available and would cost up into the thousand(s) of dollar range and would be what the fire department uses. Our alarms are more or less geared toward healthy people."
Is the above not a serious concern? What I'm getting out of this conversation is:
1) If you are healthy we will help you stay that way (help keep you alive).
2) If you are elderly, have a respiratory issue/concern or are otherwise handicap and could possibly die from inhaling Carbon Monoxide of '70 PPM or less during the time it takes for the alarm to sound; they just don't care ... or (see item 3)
3) Pay whatever manufacturer that makes a Carbon Monoxide detector that will alert you immediately (without delay), one thousand dollars ($1k) or more to save the lives of your household members.
Why is there a double standard. While we can understand the fire depts. Need to detect CO levels immediately, what about our need to live? For this reason, there is `no' Carbon Monoxide detector currently sold by Kidde that could get any rating higher than a one (1) star.
Given the contents of this review, we would hope others such as yourself would continue this trend by using this review as a guide and ask these manufacturers
"why the delayed alarm when the detectors do in-fact sense/detect Carbon Monoxide within approximately three (3) minutes of introducing CO to the Detection device."
