Features and Operation of Digital Display Model (cont.)

Peak Level Display (Cont.)

The peak level feature is helpful in identifying low level CO occur- rences below 30 PPM. Although the unit will not automatically display levels below 30 PPM, it will detect and store these read- ings in memory. By pressing the peak level button, concentration levels as low as 11 and up to 999 PPM will be displayed.

Concentrations of CO between 0 and 30 PPM can often occur in normal, everyday conditions. Concentrations of CO below 30 PPM may be an indication of a transient condition that may appear today and never reappear. Just a few examples of conditions and/or sources that may cause low level readings are heavy automobile traffic, a running vehicle in an attached garage, an appliance that emits CO when starting up, a fire in a fireplace or charcoal in a nearby barbecue. A temperature inversion can trap CO generated by traffic and other fuel burning appliances causing readings of CO.

Some CO conditions may start out as low level leaks but could develop into CO concentrations that could become harmful. If this happens, the CO alarm will detect the dangerous level and alarm, notifying you and others of the conditions. DO NOT ignore high concentration readings above 30 PPM or a CO alarming device that is in alarm. Refer to page 18 for more details.

Features and Operation for Digital Display Model (cont.)

Resetting the Peak Level Reading

To reset or clear the peak level reading, press and hold the peak level button and then press and hold the test/reset button at the same time. The number on the display will return to 0 PPM. CO concentrations displayed below 30 PPM in memory are for ref- erence only and the accuracy of the concentration shown may not be as accurate as noted on page 26.

Note: The peak level reading will also be reset when the batteries are removed.

In the rare event that your alarm malfunctions, it will alert you with a short “chirp” and the red LED will flash once every 30 seconds. The digital model will display “Err” as shown in Fig. 6.

Seven years after initial power up, this unit will "chirp" every 30 seconds to indicate that it is time to replace the alarm. The unit will not detect CO in this condition. Please replace immediately.

Note: Your Kidde CO Alarm will NOT monitor CO levels while an error warning is being displayed.

Low Battery If the batteries become “low”, the alarm will alert you with a short “chirp” and the red LED

will flash once every 30 seconds for up to 7 days.

The digital models will display “Lb” as shown in Fig. 7.

KN-COPP-B, KN-COB-B specifications

The Kidde KN-COB-B and KN-COPP-B are advanced carbon monoxide (CO) and natural gas detectors designed to provide essential safety features for homes and workplaces. These devices are engineered to alert occupants of the presence of carbon monoxide or natural gas, which can pose serious health risks or even be life-threatening in high concentrations.

The KN-COB-B model is a sensitive CO detector that uses electrochemical sensor technology to accurately monitor levels of carbon monoxide in the environment. With a digital display, it provides real-time readings, allowing users to keep track of CO levels effectively. The detector features a peak level memory that recalls the highest CO level recorded since the last reset, which can be invaluable for pinpointing exposure at specific times. An alarm will trigger when dangerous levels of CO are detected, ensuring timely intervention and safety.

On the other hand, the KN-COPP-B model is designed to detect natural gas leaks, including methane and propane. It utilizes a state-of-the-art semiconductor sensor that provides reliable performance and swift response times. Like its counterpart, it features a robust alarm system, ensuring that occupants are alerted as soon as gas concentrations reach dangerous levels.

Both models are equipped with a test/reset button that allows users to easily check the functionality of the alarms, ensuring that they remain in working order at all times. They also come with an easy-to-read LED display that shows the status of the device, including the presence of CO or natural gas.

Design-wise, these detectors are sleek and compact, fitting seamlessly into any home or office environment. They can easily be mounted on walls or placed on flat surfaces, providing flexibility in placement options. Each model comes with an AC power adapter for continuous use, supplemented by a battery backup that ensures operation during power outages.

Together, the Kidde KN-COB-B and KN-COPP-B provide a comprehensive solution for monitoring both carbon monoxide and natural gas levels, making them essential safety devices for any modern living or working space. Their advanced technologies, user-friendly features, and high reliability make them a top choice for consumers seeking peace of mind regarding air quality and safety.
