Carbon monoxide poisoning can come about via a number of sources, including everyday items and appliances in your home or office.

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 LevelsThe 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 StatusWith 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.

Review: Quality CO detector. Worthwhile investment. - Quality Kidde brand CO detector. I replaced my original one with this identical one after 10 years of service, when it finally beeped and showed "END" in the display, which renders it useless, which is by design. Ironically, I never had any CO issues or alerts, until about a few months before its 10th anniversary in service. My home's natural gas boiler was over 25 years old, and begin leaking CO from incomplete combustion issues. This Kidde CO detector audibly alerted me and displayed the current CO level as well as the maximum CO level that it had recorded. Very simple to use and displays basic, yet useful information. I was able to open the windows and ventilate my house to prevent the excess CO buildup from harming us, thanks to this CO detectors audible & visual alerts. Hope they're still making this model 10 years from now, when I will need another one, or if I decide to move and want to purchase a new one. It's certainly not the cheapest CO unit on the market, but it's a good value for the money. Oh, it plugs directly into any standard 110-volt power outlet and it has a 9-volt battery backup, battery included. Although they recommend you replace the 9V backup battery every few years, I never replaced mine, and it was still almost as good as the day it was installed. My Kidde CO detector is plugged into an outlet in our upstairs hallway just outside of our bedroom. Fortunately, it also fit perfectly next to (below) my plug-in doorbell, which was a huge plus! I'm planning on installing one in the basement, near the gas boiler as well. Should have done that years ago, as we would have likely received an earlier "heads-up" that there was a combustion problem with the boiler. One last note: You can remote wall-mount this unit also. Cool feature! If you look at the last picture that I posted with this review, you can see that when the rear access cover is removed to access the backup battery, there is extra cord stored on the opposite side of the battery. The connected main power source plug can be easily removed and relocated/extended, via the corded connection, in order to have the CO detector located somewhere other than directly plugged into the power source. There is also a handy little clear plastic packet included, containing two wood/mounting screws and two wall mount plastic expanding inserts. (Not shown in picture.) Just can't say enough good stuff about this unit. Very pleased with it!

## Questions & Answers

**Q: what is the manufacture date on this? I see a lot of reviews showing old out of date units received.**
A: Ordered in January 2017.  Date of manufacture: October 2003.  People must be careful when ordering these, especially from third party sellers.  I bought one from a third party seller for a ridiculously low price -- big mistake, as the unit was over 13 years old!  (Note: The date of manufacture is on a label on the BACK of the unit, which is not visible when the unit is encased in its original packaging.  There is no way to know the date of manufacture unless you physically remove the unit from its hermetically sealed packaging and examine the label on the back of the unit.)

**Q: Can the alarm funtion be disabled? i want to use in a space where i want higher than normal levels of co2.**
A: Do NOT simply clip one wire to the transducer as in a smarter device a monitoring voltage may discover the alarm is disabled and disarm the monitor entirely. Depending on construction, you also should not remove any coating from a pcb and unsolder the correct terminal. That would probably break the alsrm and a federal statute.

**Q: The Kiddi web site says this has a 10 year life and 10 year warranty for this model900-0076. Are these old ones that your selling?**
A: My old one lasted 7years 5 days 36 minutes.  I just put the new models in and they work fine.  As far as how long they warranty 10 years.

**Q: Can someone explain how to insert the battery?**
A: Remove unit from packaging and turn unit so the AC power connector is facing you.  There is a U shaped section around the AC connector with a series of dashes on both upright section.  Push both of those towards the opposite end of the unit. This will unlock the U shaped cover.  Remove the cover.   My unit came with mounting screws and a drier pack that where inside the battery compartment.  The connector for the battery is visible after removing the items in the compartment.  Connect the battery and install the back cover, you are good to go!

### ⭐⭐⭐⭐⭐ Inexpensive insurance.
*by K***R on January 20, 2026*

I have a number of these throughout our house. They have worked flawlessly. They alerted once when a carpet cleaner turned on his generator while his vehicle was inside our garage. Numbers were high enough that the fire department ventilated our house. Could have been a disaster had they not alerted us. This purchase replaced a similar one that failed after many years. Made in Mexico now, but I expect the same performance. Battery backup is important to me as we experience frequent power failures.
