The First Alert CO400 is precisely identified as a dedicated carbon monoxide alarm, primarily operating on battery power. This specific model, sometimes referenced with a ‘B’ suffix like CO400B, underscores its self-contained nature, eliminating the need for electrical wiring. Its fundamental purpose is to serve as an indispensable safety device within homes and other enclosed spaces. The CO400 is engineered to vigilantly monitor the ambient air for the presence of carbon monoxide, a highly toxic gas that is imperceptible to human senses. By utilizing advanced sensing technology, the alarm’s main objective is to detect unsafe CO concentrations and promptly alert occupants through a loud, unmistakable signal. This early warning capability is critical for facilitating timely evacuation and preventing severe health consequences or fatalities associated with CO poisoning. Recognizing the CO400 model number is essential for users, as it ensures they are consulting the correct operational guidelines and support resources, thereby maximizing the device’s protective function. Its design focuses on reliable, continuous protection, making it a cornerstone of household safety.
Key Features of the Battery-Operated Alarm
The First Alert CO400 stands out primarily due to its reliable battery-operated design.

The Importance of Carbon Monoxide Detection
The significance of carbon monoxide (CO) detection cannot be overstated, as this invisible, odorless, and tasteless gas poses a grave threat to human life. Often referred to as the “silent killer,” CO is a byproduct of incomplete combustion from common household appliances like furnaces, gas stoves, water heaters, and even vehicles operating in enclosed spaces. Its insidious nature means that without a dedicated detector, occupants are completely unaware of its presence until symptoms, which often mimic the flu, become severe or even fatal. Exposure can lead to headaches, dizziness, nausea, confusion, and eventually unconsciousness, brain damage, or death. Devices like the First Alert CO400 are therefore indispensable. They provide the only reliable early warning system, sounding a loud alarm when dangerous levels of CO are detected. This crucial alert grants individuals the precious time needed to evacuate and seek fresh air, preventing severe health consequences or tragic fatalities. Installing and maintaining such an alarm is a fundamental step in safeguarding any home against this pervasive and deadly hazard, ensuring peace of mind and protection for all occupants.
