WHY LOW-LEVEL MATTERS

Your store-bought alarm waits too long.

Standard CO alarms sold at retail don't sound until carbon monoxide reaches 70 ppm or higher — and only after hours of exposure. By then, you may already feel the effects of CO poisoning. Infants, children, the elderly, and anyone with respiratory or heart conditions get little or no protection from those alarms.

The NSI 6000 starts reading CO at just 5 ppm and sounds its first alert at 15 ppm. It warns you of a problem long before dangerous — even deadly — levels, and long before other detectors even begin to work.

GOOD TO KNOW

A monitor, not a replacement.

The NSI 6000 is a low-level CO monitor — it does not replace a UL-listed CO alarm or smoke alarm required by code. It works alongside them, catching the low-level exposure those alarms are designed to ignore. If any CO alarm sounds, get everyone outside and call 911 from outside.
