Features

•Permanent independent smoke and carbon monoxide sensors (ionization and electrochemical).

•Loud 85 decibel alarm.

•Alarm/Voice message warning system that specifies which dangerous condition exists, eliminating any confusion over which alarm is sounding:

FIRE: The alarm/voice pattern is 8 seconds of alarm beeps followed by the verbal warning message, “Fire! Feu!” This pattern is repeated until the smoke is eliminated. The red LED light will flash while in alarm/voice mode.

CARBON MONOXIDE: The alarm/voice pattern is four short alarm beeps followed by the verbal warning message, “Carbon Monoxide! Monox y d e de Carbone!” This continues until the unit is reset or the CO eliminated. After four minutes the alarm/voice pattern will sound once every minute. The red Light Emitting Diode (LED) light will flash while in alarm/voice mode.

LOW BATTERY: When the batteries are low and need replacing the red LED light will flash and the unit will “chirp” one time, followed by the warn i n g message, “ L ow Battery. P i l e Faible!” This cycle will occur once every minute for the first hour. After the first hour the red LED light will continue to flash every minute accompanied by the "chirp" only sound. The voice message “ L ow Battery. P i l e Faible!” will sound once every fifteen minutes during the “chirp” only cycle. This will continue for at least seven days.

•One “chirp” every 30 seconds is an indication that the alarm is malfunctioning. If this occurs call the Consumer Hotline at 1-800-880-6788.

NOTE: After seven (7) years of cumulative power up, this unit will "chirp" every 30 seconds. This is an "operational end of life" feature which will indicate

4that it is time to replace the alarm.

Features

•Oversized test button for easy activation.

•Test button performs the following functions:

Tests the units electronics and verifies proper unit operation

Resets the unit during CO alarm Activates HUSH® Feature (see Page 16). Peak Level Memory (See Page 17).

•Mounting bracket designed for easy orientation of unit.

•Green and red LED lights that indicate normal operation and alarm status.

Green Light: The green Light Emitting Diode (LED) flashes every 30 seconds to indicate the unit is operating properly, and once every 2 seconds to indicate the unit is in HUSH® mode. The green light also flashes before a CO reading is taken and when any button is pressed.

Red Light: When a dangerous level of smoke or carbon monoxide is detected the red Light Emitting Diode (LED) will flash and the corresponding alarm pattern (depending on the source) will sound. If the unit malfunctions, the red LED light will flash and the unit will chirp every 30 seconds indicating a system problem.

•Powered by three (3) AA batteries.

•Battery lockout system that prohibits installation without using three batteries.

•Smoke alarm takes precedence when both smoke and carbon monoxide are present.

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.
