Product Description

Product 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.
