Sample Peak
Level Reading

6.Model KN-COPP-B (with digital display) Operating Characteristics

Peak Level Memory (model KN-COPP-B only)

When the Peak Level button is pressed and held, the display shows the highest CO reading taken by the CO alarm since its

last reset or power up. In this example 120 PPM was the maximum amount of CO recorded since the unit was last reset.

The Peak Level display feature will display levels between 11-999 PPM. Although the Peak Level fea- ture 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. The Peak Level feature is helpful in identifying if you have had a CO reading since resetting the alarm.

Concentrations of CO between 1 and 30 PPM can often occur in nor- mal, everyday conditions. Concentrations of CO below 30 PPM may be an indication of a transient condition that may appear today and never reappear. Some CO conditions may start out as low level leaks but could develop into CO concentrations that may 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 con- centration readings above 30 PPM or a CO alarming device that is in alarm.

Peak Level Memory Reset

Press the Peak Level button; with the button still pressed, press the Test/Reset button for two seconds and release. The number on the dis- play will turn to “0”, the memory will be cleared and the alarm will begin monitoring for CO. The Peak Level memory is also reset when the unit loses power.

7. Alarm Characteristics

Carbon Monoxide Alarm Indicator

When the alarm senses a dangerous level of CO, the unit will emit a loud alarm pattern. The alarm pattern is 4 quick beeps followed by 5 seconds of silence, repeating for 4 minutes – and then 4 quick beeps once every minute as long as dangerous CO conditions exist. The red Alarm LED will flash the same pattern and the digital display (where equipped) will indicate CO concentrations in parts per million (PPM).

8. Maintenance

NOTE: This unit is sealed. The cover is not removable.

Due to the loudness of the alarm, we suggest that you place your fingers over the sounder opening while testing your alarm.

Caution: Continuous exposure to the high sound level of this alarm over an extended period of time may cause hearing loss.

Testing

To test the alarm, press the Test/Reset button. If the unit is operating properly, you will hear 4 quick beeps – followed by 5 seconds of silence

–followed by 4 quick beeps. (For model KN-COPP-B with digital dis- play: The display will show three “eights” and then show a number – usually around 200). The red LED will flash along with the beeps. Within several seconds the unit will return to monitor for CO. Note: You do not need to press the Test button to take a CO reading.

Maintenance Tips

To keep your alarm in good working order, you must follow these steps:

•Test the alarm once a week by pressing the Test/Reset button.

•Vacuum the alarm cover once a month to remove accumulated dust.

•Never use detergents or solvents to clean the alarm. Chemicals can permanently damage or temporarily contaminate the sensor.

•Avoid spraying air fresheners, hair spray, paint or other aerosols near the alarm.

•Do not paint the unit. Paint will seal the vents and interfere with proper sensor operation.

KN-COPP-B-LS (900-0230), KN-COB-B-LS (900-0233) specifications

The Kidde KN-COB-B-LS (model 900-0233) and KN-COPP-B-LS (model 900-0230) are state-of-the-art devices designed for enhanced safety in homes and workplaces through advanced carbon monoxide (CO) and smoke detection. These two models exemplify Kidde’s commitment to providing reliable protection against potentially life-threatening situations.

The Kidde KN-COB-B-LS features an electrochemical carbon monoxide sensor, which provides accurate detection of even the smallest concentrations of CO. This model typically has a digital display that continuously shows CO levels in parts per million, allowing users to monitor levels in real-time. It is equipped with a voice alarm that offers clear and concise warnings when CO is detected. Additionally, the KN-COB-B-LS has a peak level memory feature that records the highest CO level detected, which is useful for understanding exposure over time.

On the other hand, the KN-COPP-B-LS is a combined smoke and carbon monoxide alarm, integrating dual-sensor technology for comprehensive monitoring. This unit utilizes both photoelectric and ionization sensing technologies. The photoelectric sensor is particularly effective at detecting smoldering fires, while the ionization sensor is better suited for fast flaming fires. This combination increases the effectiveness of fire detection, giving users an earlier warning in emergency situations. Similar to the KN-COB-B-LS, the KN-COPP-B-LS also features a digital display for CO levels and a voice alert system for immediate notifications.

Both devices are easy to install and come with a battery backup to ensure uninterrupted operation during power outages. They feature a test/reset button that allows users to verify functionality and a low battery warning system that alerts users when it's time to replace the batteries. The compact design and modern aesthetics of both alarms ensure they blend seamlessly into any environment.

Furthermore, these models comply with the latest safety standards, providing reassurance to homeowners and businesses alike. With an impressive lifespan of up to 10 years, these Kidde alarms are not only durable but also provide long-term protection against the dangers of smoke and carbon monoxide. Investing in the Kidde KN-COB-B-LS and KN-COPP-B-LS is a proactive step toward ensuring safety and peace of mind for you and your loved ones.
