Description

The Kidde Carbon Monoxide Detector, Propane, Natural, & Explosive Gas Alarm, Plug-In Wall with 9-Volt Battery Backup, Digital LED Display uses electrochemical sensor technology to detect poisonous carbon monoxide, methane gas, sewer gas, propane gas or natural gas in your home and alerts you by sounding an 85-decibel alarm & displaying the amount of carbon monoxide detected or stating "gas" on the digital display when detecting explosive gas. Setup is easy as the Kidde carbon monoxide alarm plugs into a standard, 120V AC power outlet in your home, while a 9-volt alkaline battery (included) works as a backup in the event of a power failure. When carbon monoxide is detected, the digital display shows the level of carbon monoxide the alarm is sensing and updates every 15 seconds. Peak Level Memory records the last time carbon monoxide was detected or when the unit was tested. The Smart-Hush button silences the unit for approximately 8 minutes, which is helpful when this smoke detector carbon monoxide detector combo sounds from things like routine cooking or shower steam. Extension cord (included) allows for placement on a table or shelf. Install a carbon monoxide smoke detector combo on every level of your home and near bedrooms to help keep your family safe. UL Certified with a 10-year limited manufacturer's warranty. Meets requirements of UL 2034, UL217, NFPA72, (chapter 11 2002 edition) The State of California Fire Marshal, NFPA101 (One and two family dwellings) Federal Housing Authority (FHA), Housing and Urban Development (HUD). Protect your family from the dangers of carbon monoxide (CO), methane, and propane exposure with the Kidde KN-COEG-3 Nighthawk Plug-In Carbon Monoxide and Explosive Gas Alarm. The Nighthawk is an easy-to-install unit that provides reliable protection against the dangers of CO and explosive gas. The digital display shows if gas is present indicates CO levels in parts per million, allowing you to see if, how, and when levels change.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.About Kidde: A UTC Fire and Security Brand Renowned for global leadership in fire detection and suppression, Kidde provides solutions ranging from portable fire extinguishers to advanced industrial controls such as flame detection and explosion suppression systems.

  • A no-brainer – works well, good price, good quality, great peace of mind
Pattern Name: Detector
I have used several of these for several years. In one area of my home I have one near a fireplace with a gas insert and in a central portion of my home. It is a great peace of mind to know that both carbon dioxide and all forms of natural gas will be monitored. I think the price is fair. The quality is good. The unit is substantial and simple to use. Can ask better than that. ... show more

  • Seems to be good, but how would I really know?
Pattern Name: Detector
No complaints about this, but I have no way to really test its accuracy and sensitivity, so I have to take that part on faith. But the Kidde name warrants that faith. I do really like the device. MANY of these have a fixed AC plug on the back that requires one to place it at an outlet or to run an extension cord to the correct location for mounting. In our case, we are monitoring for natural gas, and that means the power source must be up near the ceiling. Of course, homes rarely have power outlets near the ceiling, and if they do, those are dedicated to TVs and such. So the only option is to run an extension cord or power strip to the proper location, mount that to the wall somehow, and then plug in the device into the power supply cord. That's ridiculous and unsightly. Those will work great for propane, but not for natural gas. The Kidde has a long (about 6'), low voltage extension cord attached to a conventional wall wart (transformer power supply) on the end that reaches down to a convenient outlet and feeds power to the device in a proper location reasonably near the ceiling. Installation is easy with the small "mollys" to hold adequately in sheetrock. The device is light enough that it doesn't take much to hold it securely. The LED display, which, I believe, is a continuous readout of CO levels, is large and bright enough to read from across the room. I've installed this primarily to monitor for natural gas leaks. Since moving in, we have removed THREE natural gas appliances: a gas range, a gas "fireplace" and a gas hot water heater. The only remaining gas appliance is the furnace. With a running furnace and three capped off gas spigots, this detector provides peace of mind about gas leaks. The CO detector is a bonus, and it's good to know that the furnace is properly vented and not leaking combustion byproducts. I'm pleased with this purchase, and I recommend it. ... show more

  • It's a bear to get battery cover off.
Pattern Name: Detector
The unit works very well and is quite sturdy and simple to use. However I had to resort to you tube videos to get ideas how to get the battery cover off... If you are like me with only moderate hand strength use a sturdy screwdriver to help get battery cover to move. Was NOT easy even with the driver. This should be addressed by manufacturer. Plenty of people complaining about this issue. ... show more

  • A lot of misinformation in negative reviews
Pattern Name: Detector
I didn't have a natural gas detector so I got this one to put in my basement, which is the only place in my home with natural gas. Installation is easy, just plug it in. The plug portion can be removed from the back of the unit and the main part located at a different level than the plug. Natural gas is lighter than air and propane is heavier so they recommend that it be located high in the room if you have natural gas and low if you have propane. A lot of the negative reviewers don't appear to understand when the unit is supposed to sound the alarm. Carbon monoxide is poisonous at high concentrations. Natural gas and propane are not poisonous but can be explosive at high concentrations, the levels are well established. At very high concentrations they can cause suffocation because they displace oxygen. The packaging says that it might take up to 4 hours to sound depending on the concentration of CO, this is consistent with the UL standard. In fact a unit would fail the UL test if it went off within 30 days when there are low levels of CO. This is to minimize nuisance alarms, the alarm wouldn't do any good if people got frustrated and disabled it. The gas detector alarm is specified to sound by the time the concentration reaches 25%, this is below the explosive threshold. Just because there is a heavy gas odor doesn't mean there is an immediate danger. One negative reviewer tried to test it with a cigarette lighter, which typically use butane. This unit is only specified to test for natural gas (methane) and propane. The warranty is 5 years, the unit will stop working after 7 years and should be replaced. This is a safety feature, not planned obsolescence. ... show more
