The Remote CO2 Storage Safety Alarm is designed to protect customers and workers near stored carbon dioxide (CO2). CO2 alarms are critical in dry ice storage, laboratories, or anywhere more than 100 lbs. of compressed CO2 is stored or produced.

The monitor has both audible and visual alarms. Three built-in relays are triggered at 5,000 ppm TWA, 1.5% CO2, and 3% CO2. They can trigger an exhaust fan or send an alert to the fire department or monitoring company. This device meets fire inspection code requirements regarding stored carbon dioxide.
