Advanced Technology in an Easy-to-Install, Plug-In Design
Designed for home use, the Kidde KN-COEG-3 Nighthawk is a UL-listed, A/C-powered, plug-in alarm that utilizes sophisticated electronic components and sensor technology to protect you and your family from the dangers of CO, methane, and propane exposure. It plugs directly into a standard A/C outlet and includes a 9-volt battery backup that provides continuous monitoring--even during power outages.

The Dangers of Carbon Monoxide, Methane, and Propane Exposure
The leading cause of accidental poisoning deaths in North America, carbon monoxide (CO) is often referred to as the silent killer because it's odorless, tasteless, and invisible. Carbon monoxide poisoning can come about via a number of sources, including everyday items and appliances in your home or office. And because symptoms of CO poisoning mimic the flu or other common illnesses it can often go undiagnosed.

Likewise, methane and propane gases are commonly used in homes for cooking, heating, and water heating. Although it happens rarely, gas leaks can sometimes occur inside the home, increasing the risk of fire or explosion.

Audible Alarm Pattern Alerts you to Elevated CO and Gas Levels
When placed on every level of your home, alarms like the KN-COEG-3 Nighthawk can help protect everyone in the house by giving you an unmistakable signal when gas levels have reached an unhealthy point. If unhealthy levels of CO are detected, the alarm will emit four quick audible beeps every five seconds until either levels decrease or the reset button is pressed. If methane gas or propane gas is detected, the alarm will emit beeps every other second with "GAS" shown in the display.

Easy-to-Read Digital Display Shows CO Levels
The KN-COEG-3 Nighthawk is preferred among traditional CO and explosive gas 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. The continuous display also shows if gas is present.

LED Shows Sensor Status
With the KN-COEG-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. In addition, you can test alarm function by pressing the test/reset button at any time to verify that the horn and electric circuitry are operating properly.

Convenient Mounting Options
The KN-COEG-3 Nighthawk has a low-profile design that makes it suitable for any room in your home. The detector can be plugged into any standard A/C outlet; it's plug can be snapped into the back of the unit and can be rotated so the alarm remains vertical, independent of whether the electrical socket is mounted vertically or horizontally. In addition, the alarm comes with a 6-foot extension cord, so the unit can be plugged into the wall outlet and then placed on a table or shelf. For the most thorough protection, place an alarm on every level of your home.

The UL-listed Kidde KN-COEG-3 Nighthawk has a seven-year life and is backed by a five-year limited warranty.

Fortunately, Kidde customer service has responded well to our false alarm problem with the GAS side of these devices.

Now on our third, the other two each lasted about a year before giving us false GAS alarms, this one is up only about 2 months and here we go again!

This time, I asked Kidde if they would replace the unit with the Carbon Monoxide ONLY product... They were kind enough to do so.

Thank goodness Kidde stands behind their products with representatives trained to listen and respond to consumer issues.

In our family this is known as the FBT (B=beepie T=thing and the F I will leave to your imagination.)

The problem? It works. Too well. It works if you bake a fish, refinish a floor, vacuum near it, burn some toast, do your nails, spray air freshener, run a space heater.... you get the picture. It has a piercing, screaming wail that will drive you insane. And a battery back-up to insure that should a frustrated homehowner try to shut it up by taking it outside and throwing it into the wet bushes, say, or even a pile of snow, it will continue to beep all night long. Loudly. Prompting a police call from a concerned neighbor. It has an apparently infinite power source. Terrorists would do well to stock up on several of these at the new low price.

I wonder how many of these have been destroyed by irate consumers?

Picture this: you have just sanded a floor and are nearly finished applying the polyurethane when the FBT chooses that very moment to go off. You look up sadly across the expanse of newly varnished floor, realizing there is no way to reach the FBT and throw it against a nearby tree. You know that cutting the power to that outlet will do you no good because your ultra responsible husband put in fresh batteries recently. What to do?

Simple. A hotel.

Do not buy the FBT. Unless you are a sadist.

We began experiencing false alarms with this gadget at a disturbing rate. At first, we panicked, believing that our lives might be in jeopardy at the time of each alarm. After "airing" the gadget out, we reset and reinstalled the gadget several times but it continued to give GAS alarms. Finally, we went online and read the reviews of this gadget and learned of its propensity to give "false alarms". Particularly helpful was the family that reported that they had lovingly renamed the gadget their "FBT" - short for the "Fart Beepy Thing". That gave us the idea for how to realize the true value of our very own FBT.

If you walk by the gadget and let one rip (i.e. backfire or blow mud), the gadget will go off in anywhere from 10-60 seconds and begin flashing the GAS alert. The length of time it takes to set the alarm off depends upon the severity of the individual air biscuit that was released. From our experience, Sloppy Joe mud ducks are far worse than cheap beer stink bombs. The best part is that, after setting off the alarm, you can then press one of the buttons and the gadget will quantify your stink burger, giving you a numerical rating of the severity of the blast. From our experience, a 200 level rip reflects a modest beer blast, while a 218 level reflects a much more serious effort. So far, the best exterminator we have been able to register was a 221 beauty that surely resulted in a clothing change. Just think of all the party and gaming opportunities this gadget presents. It is well worth the price of purchase as a party activity.

By the way, this gadget probably sucks as a life saving device because you have no way of distinguishing a routine doggy blaster from a more serious Natural Gas leak. We think a caged parakeet may be more reliable in this regard. When it stops chirping, you know to get the hell out of your house.

The explosive gas part of this detector has given us several false alarms (very disturbing in the middle of the night). We just had the gas company come and make sure we don't have a gas leak and the gas man said he sees false positives on these combo units all the time. He recommends a CO only detector. Gas has an odor so unless you have no sense of smell, you can tell if you have a leak. We threw out our $60 Nighthawk and will buy a CO only detector now.

It might seem like a good idea to get this detector since it's only a few bucks more than the standard CO detector. But unless you really enjoy the sound of the 85 decibel alarm you might want to reconsider because this thing will be going off constantly.

We had the gas company come to check for a leak when the alarm sounded and the service man told us that they hate these things cause they are nearly always false alarm for explosive gas. In addition he said the display always seems to show a peak level of 220 for CO. So I checked ours and sure enough, 220 was the peak level recorded.

The problem with the unit is that it doesn't just detect natural gas or LP. Many chemicals like paints, thinners, solvents, aerosol products, etc. are likely to set it off. Two of our false alarms were caused by somebody using hairspray in a room adjacent to the hallway where the alarm was located.

Bottom line, CO is odorless, colorless and lethal so you definitely need a detector. But the CO/Gas combo unit is junk, stick with the straight CO detector. The gas company adds the smell to natural gas for a reason. You already have a detector for it; your nose. If you smell gas get out.
