Facts You Should Know to Protect Your Family

Why do I need a low-level monitor?

The NSI low level monitor senses CO levels as low as 5 ppm (parts per million). Infants, children, elderly, persons with respiratory or heart ailments are provided little or no protection from deadly CO with standard alarms. Long term exposure to Low-level CO above 15 ppm can cause illness and even permanent disabilities.

What about the other “detectors” sold at retailers and home centers?

Store-bought detectors don’t alarm until unsafe levels of 70 ppm or higher are present at the unit for 3-1/2 hours! By then it may be too late. Plug-in models don’t always allow for proper placement and don’t work during power outages. The NSI 3000 is battery powered for 24/7 protection.

Why is the NSI 3000 more expensive than the others?

Accurate, low-level CO detection requires more expensive components & quality control. The NSI 3000 CO monitor uses the same technology and sensors as in professional-grade CO analyzers used by contractors, fire departments, and utilities.And NSI’s unique Continuous Scan™ mode lets you know the monitor is operational 24/7!

Why do I need a low-level monitor?

As with smoke detectors, you should have one monitor installed on every level of your home. Even a single story home may need two, one at each end.

Where should I place the NSI monitor?

CO is lighter than air. Monitors should be mounted at eye level and no lower. They should be placed in an area with good air circulation. If you have only one monitor it should be placed near the master bedroom. Additional locations include your kitchen, nursery, basement, rooms with fireplaces or gas logs, and near your heating system and/or hot water tank.Your professional installation contractor will determine the best location in your home.

What should I do if my monitor goes off?

The NSI low level monitor senses CO levels as low as 5 ppm (parts per million). Infants, children, elderly, persons with respiratory or heart ailments are provided little or no protection from deadly CO with standard alarms. Long term exposure to Low-level CO above 15 ppm can cause illness and even permanent disabilities.
