Operation

D e t e rmining what type of alarm has sounded is easy with the Kidde Combination Smoke/CO Alarm. The voice message warning system will inform you of the type of situation occurring. Refer to the Feature s section for a detailed description of each alarm pattern .

HUSH® Control Feature

The HUSH® feature has the capability of temporarily desensitizing the smoke alarm circuit for approximately 10 minutes. This feature is to be used only when a known alarm condition, such as smoke from cooking, activates the alarm. You can put your Smoke/CO Alarm in HUSH® mode by pushing the test/reset button. If the smoke is not too dense, the alarm will silence immediately and the green LED will flash every 2 seconds for approximately 10 minutes. This indicates that the smoke alarm is in a temporarily desensitized condition. The unit will automatically reset after

a p p roximately 10 minutes. When the unit re t u rns to n o rmal operation after being in HUSH® mode the

a l a rmwill sound if smoke is still present. The HUSH® feature can be used repeatedly until the air has been c l e a red of the condition causing the alarm. While the unit is in HUSH® mode, pushing the test/reset button on the alarm will also end the HUSH® period.

NOTE: Dense smoke will override the HUSH® control feature and sound a continuous alarm.

CAUTION: Before using the alarm HUSH® feature, identify the source of the smoke and be certain a safe condition exists.

Operation

Peak Level Memory

If the CO sensor has detected a CO level of 100 PPM or higher since last reset, it will be recorded by the Peak Level Memory function. To access the Peak Level Memory press the test/reset button. If a reading of 100 PPM or higher has been recorded the unit will chirp 8 times. If you’ve been away from home this feature allows you to check if there was a CO reading of 100, or higher, during your absence. Pushing the test/reset button resets the memory. It’s also reset when batteries are removed.

KN-COSM-BCA specifications

The Kidde KN-COSM-BCA is a highly rated combination smoke and carbon monoxide alarm designed to enhance home safety. This device integrates advanced technologies that provide comprehensive protection against two of the most critical household threats: fire and toxic gas exposure.

One of the standout features of the KN-COSM-BCA is its dual-sensor technology, which combines both photoelectric and ionization sensors. The photoelectric sensor is especially effective at detecting smoldering fires, which often produce a large amount of smoke without an open flame. On the other hand, the ionization sensor is more responsive to fast-burning fires, ensuring that users are alerted promptly in the event of any fire emergency. This combination ensures a higher level of accuracy in distinguishing between potential threats, thus reducing the chances of nuisance alarms.

Carbon monoxide detection is another critical component of the Kidde KN-COSM-BCA. Carbon monoxide is a colorless, odorless gas that can be lethal even in small amounts. The alarm features a powerful CO sensor designed to detect dangerous levels of carbon monoxide quickly and accurately. The device's LED display shows real-time CO levels, allowing users to be informed about their indoor air quality at a glance.

Another key characteristic of the Kidde KN-COSM-BCA is its voice alarm feature. Instead of just a series of beeps, the alarm announces the type of hazard detected, either “Fire” or “Warning: Carbon Monoxide.” This clear communication helps users quickly understand the nature of the threat, facilitating timely responses and safety measures.

The device is equipped with a hush feature to temporarily silence unwanted alarms, making it convenient during cooking or other activities that may trigger false alarms. Additionally, its battery-operated system, backed by a reliable lithium battery, ensures that the alarm remains functional even during power outages, enhancing household safety at all times.

Furthermore, the Kidde KN-COSM-BCA comes with a test/reset button, allowing users to regularly check the functionality of the unit, ensuring peace of mind. Its sleek design enables easy installation in various locations throughout the home, from hallways to bedrooms.

In summary, the Kidde KN-COSM-BCA stands out due to its dual-sensor technology, advanced carbon monoxide detection, clear vocal alerts, and user-friendly features, making it an essential addition to any safety-conscious household.
