Tools and Hardware Reviews of Kidde KN-COPP-3 Nighthawk Plug-In Carbon Monoxide Alarm with Battery Backup and Digital Display
Customer Review: Keeping us safe from Carbon Monoxide for several years now...
Summary: 5 Stars
Two mature adults with pets, we have used various CO detectors for about 12 years, The KN-COPP-3 has been here for the last 3.
Was glad to upgrade to a unit that had digital readout and battery backup, looked at many and this one stood out for features and price. I change the 9v battery when I do the smoke alarms every year and they still have enough power left to use in something less important like a radio or VOM.
Now and then I will unplug it and use as a handheld detector as I walk around the house and into the basement to check for any leaks. As they tell you, you will get SOME reading right around items that produce CO but as long as the levels are within limits you know you are safe.
The first one we bought from a Mom & Pop type general store that had only one left and had a clearance price on it.. could not believe my luck in running into the model I wanted when I was not even looking for it.
However, I could not get that unit to setup properly with readings all over the range etc.
Called Kidde and found out that you need to let them get exposed to the interior of your house for some hours before you plug them in, seems the packaging can foul the sensor after a time.
Even that did not help so I called Kidde again... they ask me to read the date on the unit, turns out that you need to replace them every 5 years and this one was already past the "use by" date when I bought it and should not have been sold.
Kiddie, sent me a replacement unit right away and that has been working for several years now. That is good service, when they found out that the store I bought it at was out of town and I could not return it, no more questions, they took my address and sent me a replacement!
So.. be sure to check the date on yours so you know it's a recent build to get your full years use out of it. Then also record the date in your planner so you can replace it before it has a chance to fail from old age. I see Kidde might have increased the time to 7 years now, even better with the same price.
