Facts About CO In Homes

Invisible, odorless carbon monoxide (CO) is the #1 cause of accidental poisoning deaths in the United States, claiming approximately 480 lives and sending another 15,200 people for treatment annually. New, energy-efficient construction actually compounds the problem, trapping more CO inside where it can build to potentially dangerous levels.

Toxic CO levels can occur suddenly, or accumulate slowly over time. FireX® utilizes technology that is equally effective under both conditions.

Because even a very small, slow buildup of CO can cause health problems and eventual death, FireX alarms monitor CO levels continuously, and sound an alarm whenever potentially dangerous conditions occur.

Carbon monoxide alarms are mandatory in many states. FireX helps you meet both health and regulatory concerns.
