Features
The KN-COPP-LPM is an essential device to help warn you and your family of dangerous carbon monoxide levels in your home. This alarm measures the exposure to carbon monoxide over time; it is designed to sound at 85 decibels at 10 feet when it detects 70 ppm (parts per million) of CO for 60 to 240 minutes, 150 ppm for 10 to 50 minutes, or 400 ppm for 4 to 15 minutes. The easily visible digital display indicates the level of CO that the unit is sensing, and it updates the status every 15 seconds for timely and accurate readings. Its free-standing design allows for attachment to a wall or placement on a counter or nightstand for convenient and comprehensive protection. The KN-COPP-LPM also includes a slide-out battery door that provides immediate access to the power source as well as a battery safeguard that makes it difficult to close the cover without batteries installed. An LED lighting system on the unit signals power levels and sourcing: the green LED will flash once every 30 seconds to indicate the alarm is operating properly when power is present, and the red LED will pulse to indicate carbon monoxide has been detected until the device is reset or the CO threat is eliminated. This device has an expected 7-year lifespan and comes equipped with a five-year manufacturer’s limited warranty.

Advanced Technology in an Easy-to-Install, Plug-In Design
Designed for home use, the Kidde KN-COPP-3 Nighthawk is a UL-listed, A/C-powered, plug-in CO alarm that utilizes sophisticated electronic components and sensor technology to protect you and your family from the dangers of CO. It plugs directly into a standard A/C outlet and includes a 9-volt battery backup that provides continuous monitoring of CO levels–even during power outages.
About Carbon Monoxide: The Silent Killer
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.
Audible Alarm Pattern Alerts you to Elevated CO Levels
When placed on every level of your home, alarms like the KN-COPP-3 Nighthawk can help protect everyone in the house from CO exposure by giving you an unmistakable signal when levels have reached an unhealthy point. 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 Levels
The 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 Status
With 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. 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-COPP-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-COPP-3 Nighthawk has a seven-year life and is backed by a five-year limited warranty.

Carbon Monoxide: The Leading Cause of Accidental Deaths in the U.S.
Carbon monoxide, an invisible, odorless gas, is the leading cause of accidental poisoning deaths in America, yet many people don’t know they are suffering from CO poisoning until it’s too late. Because you can’t see, taste, or smell it, CO can kill you before you even know it’s there. Likewise, exposure to low levels over time can make you ill.
The Consumer Product Safety Commission recommends that every home have at least one carbon monoxide alarm with an audible warning signal–like the CO605–installed near sleeping areas. An alarm like the CO605 can detect the CO you can’t see, smell, or taste before it causes any physical harm to you or your family.
Electrochemical Technology for Accuracy and Longer Life
The CO605 uses an electrochemical carbon monoxide sensor–the most accurate CO sensor available. In comparison to more commonly available technologies, electrochemical technology is highly accurate, requires a lower amount of power, and boasts a longer life. If the CO605’s sensor detects a high concentration of CO, the unit will sound a clear, loud, 85-decibel alarm, giving you a chance to either ventilate the area or safely evacuate.
A/C Power with Battery Backup and User-Friendly Design
This unit runs on A/C power, but in case of an electrical outage, it will switch to battery operation. This gives you peace of mind during storms–when you’re more likely to use generators that could potentially give off dangerous levels of CO.
For added convenience, installation is a snap. Simply plug the CO605 into any wall outlet–with no additional mounting–and it’s ready to go. The unit features two ‘AA’ batteries to provide backup power to the monitor in the case of power disruption or outage.
Operation is equally trouble free. One button clearly labeled “Test/Silence” lets you test the unit to see if it’s running properly or silence it during a false alarm.
Continually Monitors Both CO Levels and Battery Power
To give you real peace of mind, the CO605 continually monitors CO and re-alarms if dangerous levels persist. At the same time, a low-battery signal let’s you know when it’s time to replace the backup batteries (included); a low-battery mute quiets the signal for up to eight hours. An easy, front-open compartment allows for easy battery changes without dismounting the alarm, and an end-of-life chirp lets you know when it’s time to replace the unit.
The CO605 comes with two ‘AA’ batteries and a five-year limited warranty. It also comes complete with an “Alarm Action” chart that instructs you on what to do if the alarm sounds.
