Features and Operation of Digital Display Model

Your new Kidde Battery Powered CO Alarm utilizes sophisticated electronic components to protect you and your family from the dangers of CO.

Unique features include a digital display capable of displaying CO concentrations in (PPM) Parts Per Million and the highest levels of CO detected. Familiarize yourself with these features:

Digital Display Backlight Feature

To help see the displayed reading in the dark, a backlight appears when the peak level button is pressed.

Digital Display - Shows CO level in PPM

Your Kidde CO alarm continuously displays a digital readout of the CO level in Parts Per Million (PPM). The digital display is capable of detecting and displaying readings between 30 and 999 (PPM). A reading of 0 PPM is expected under normal conditions (see figure 2).

Figure 2

You will become accustomed to glancing at the

display in much the same manner as you look at a thermometer or clock. The unit will not automatically display reading below 30 PPM. However, readings between 11 and 999 PPM will be stored in the Peak Level Memory.

Other Possible Displays and Their Meanings

The following symbols will appear on the display during normal or error operations, and are explained below.

Normal Operation

Normal operation (see figure 3) with a full battery.

The dot in the lower right corner cycles on and off every 5 seconds. If CO is present the display will

indicate the reading in Parts Per Million (PPM). Figure 3

Normal Operation following Power-up or Reset Figure 4 shows the normal display immediately

after installing batteries or after the test/reset button is pressed. The display should change to the normal display (see figure 3) approximately

30 seconds after pressing the test/reset button.

Figure 4

(see Test/Reset Button page 13).

 

If the test/reset button is pressed, the alarm will sound. The display will show a number during the time that the alarm is sounding. This number is a normal part of the test function, and does not indicate a CO reading.

Peak Level Display

When the peak level button is pressed and held,

 

the display shows the highest CO reading taken

 

by the CO alarm since its last peak level reset or

 

power-up(Example shown in Figure 5). The

 

backlight will illuminate for several seconds after

 

the peak level button is pressed to help see the

Figure 5

reading.

 

Although the peak level feature will display levels below 30 PPM, these levels will not result in an alarm no matter how long the device is exposed to these levels.

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.
