The advantages of the product primarily include a long sensor life of up to 10 years and battery power, which makes the device independent of power outages. A clear, backlit LCD display provides real-time information about gas concentration and device status. A loud alarm siren with an intensity of over 85 dB ensures that the warning signal will be heard even from a long distance or while sleeping.
The ATLO-CD21M detector is widely used in places exposed to carbon monoxide emissions, such as kitchens with gas stoves, bathrooms with water heaters, living rooms with fireplaces, and garages. Thanks to its compact housing and the possibility of wall mounting or use as a freestanding device, the detector is extremely versatile. Additional features, such as test mode, silent mode, and low battery signaling, make operating the device intuitive and trouble-free. Investing in this detector means peace of mind and safety for the whole family for many years.

Internal software
The device operates under the control of a dedicated microprocessor with a built-in gas analysis algorithm. The software processes signals from the electrochemical sensor in real-time, filtering interference and precisely calculating the carbon monoxide concentration. The system manages intelligent power saving, which allows for 10 years of operation on a single battery. The firmware is also responsible for self-test procedures, monitoring sensor circuit continuity, and generating appropriate sound and visual sequences depending on the threat level.
