Extreme temperatures will effect the sensitivity of the Smoke/CO Alarm. Do not install in areas where the tem- perature is colder than 40 degrees Fahrenheit (4.4 Celsius) or hotter than 100 degrees Fahrenheit (37.8 Celsius), such as garages and unfinished attics. Do not install in areas where the relative humidity (RH) is above 85%. Place away from doors and windows that open to the outside.

Smoke alarms are not to be used with detector guards unless the combination (alarm and guard) has been evaluat- ed and found suitable for that purpose.

Kidde KN-COSMXTR-B manual How to Install

KN-COSMXTR-B specifications

The Kidde KN-COSMXTR-B is a state-of-the-art combination carbon monoxide and smoke alarm designed to provide comprehensive safety for residential spaces. As an essential component of modern home safety systems, this device incorporates advanced technologies to ensure effective monitoring and alerts in case of hazardous conditions.

One of the standout features of the KN-COSMXTR-B is its dual-sensor technology, which combines both ionization and photoelectric sensing capabilities. Ionization sensors are particularly effective at detecting fast-flaming fires, making them ideal for kitchens or areas where cooking occurs. On the other hand, the photoelectric sensor excels at identifying slow-smoldering fires, often caused by burning materials. By integrating both types of sensors, the Kidde KN-COSMXTR-B offers enhanced detection reliability, significantly reducing the chances of false alarms while ensuring timely alerts during emergencies.

Another key characteristic of this alarm is its digital display, which provides real-time information about the levels of carbon monoxide present in the environment. This feature allows users to monitor CO levels accurately, understanding things beyond just standard alarm triggers. The device also includes a peak level memory that stores the highest CO reading, enabling homeowners to take necessary actions if elevated levels are recorded.

The KN-COSMXTR-B is user-friendly, equipped with a voice alarm feature that announces the type of danger detected, whether smoke or carbon monoxide. This vocal alert system is crucial, particularly for those who may struggle to recognize beeping sounds during stressful situations. Additionally, the alarm incorporates a test/reset button, making it easy to check functionality and silence the alarm when necessary.

Another notable aspect of the Kidde KN-COSMXTR-B is its battery backup. The device operates on a 9V battery, ensuring continued functionality even during power outages, which is essential for safety. Moreover, the unit is designed with a sleek and compact profile that blends seamlessly with various home decors while being easy to install, either on the wall or ceiling.

In conclusion, the Kidde KN-COSMXTR-B is an exemplary addition to any home safety setup. Its combination of dual-sensor technology, digital display, voice alerts, and battery backup empowers homeowners with reliable monitoring and peace of mind. Investing in this alarm means prioritizing safety against potentially life-threatening situations, making it a must-have for any household.
