Kidde AC Hardwired Operated Carbon Monoxide Alarm with Battery Backup alerts user to increased carbon monoxide (CO) levels in the home. This unit may be used alone or as part of an interconnected alarm system such as smoke alarms and heat detectors in the home, without requiring any rewiring. Interconnected systems provide an earlier warning because they link together, when one alarm sounds, they all sound. This provides more warning in more places, and gives individuals more time to escape.

More Information

  • Information About Carbon Monoxide:
    General Carbon Monoxide Information
    Carbon monoxide is a colorless, odorless and tasteless poison gas that can be fatal when inhaled. CO inhibits the blood’s capacity to carry oxygen.
    Periodically review this user's guide and discuss your CO alarm emergency procedure with all the members of your family. Never ignore a CO alarm. A true alarm is an indication of potentially dangerous levels of CO. CO alarms are designed to alert you to the presence of CO before an emergency – before most people would experience symptoms of CO poisoning, giving you time to resolve the problem calmly.
    Determine if anyone in the household is experiencing symptoms of CO poisoning. Many cases of reported CO poisoning indicate that while victims are aware they are not well, they become so disoriented they are unable to save themselves by either exiting the building or calling for assistance. Also, young children and household pets may be the first affected. You should take extra precautions to protect high-risk persons from CO exposure because they may experience ill effects from CO at levels that would not ordinarily affect a healthy adult.
    Symptoms of CO Poisoning: 
    The following common symptoms are related to CO poisoning and should be discussed with ALL members of the household.
    Mild Exposure:
    Slight headache, nausea, vomiting, fatigue (often described as “flu-like” symptoms).
    Medium Exposure:
    Severe throbbing headache, drowsiness, confusion, fast heart rate.
    Extreme Exposure:
    Unconsciousness, convulsions, cardio-respiratory failure, death.
    If you experience even mild symptoms of CO poisoning, consult your doctor immediately.
    Carbon Monoxide PPM Levels
    (model KN-COP-IC with digital display only)
    Model KN-COP-IC is equipped with a digital display that shows levels of CO (displayed in PPM – parts per million). Learn the difference between dangerous, high, mid and low levels.
    Dangerous Levels:
    When someone is experiencing symptoms of CO poisoning and CO readings are generally above 100 PPM. Anytime someone is experiencing the symptoms of CO poisoning this should be treated as an emergency. See “What to do When the Alarm Sounds” (inside front cover).
    High Levels:
    Generally above 100 PPM, with no one experiencing symptoms. This should be treated as an urgent situation. See “What to do When the Alarm Sounds” (inside front cover).
    Mid Levels:
    Generally between 50 PPM to 100 PPM. This should be cause for concern and should not be ignored or dismissed. See “What to do When the Alarm Sounds” (inside front cover).
    Low Levels:
    Generally below 50 PPM. Kidde recommends you take action to eliminate the source of CO. See “What to do When the Alarm Sounds” (inside front cover).
    IMPORTANT: Model KN-COB-IC does not have a digital display and does not display carbon monoxide levels in PPM. If the alarm sounds, it should be treated as a potentially serious condition. See “What to do When the Alarm Sounds” (inside front cover).
