§ FAQ

How is the KN-COU-B different from a standard CO alarm?

The KN-COU-B is designed to detect lower levels of carbon monoxide than standard residential CO alarms, which alarm only at concentrations that would cause harm to an average healthy adult. The ultra-sensitive monitor may respond to CO levels that standard alarms ignore, making it suitable for individuals with heightened sensitivity or for environments where any CO presence should be flagged.

Where should an ultra-sensitive CO monitor be placed?

Place it in living areas, bedrooms, or near fuel-burning appliances. Because of its sensitivity, it may respond to CO levels that do not require emergency action. Consult the user guide for interpretation of readings and recommended response thresholds.
