The Brasch On-Guard Carbon Monoxide (CO) Detector saves energy costs by controlling ventilation equipment in areas where high concentrations of CO may present serious health problems.  Various building and occupancy codes require that ventilation fans run 100% of the time in enclosed areas, such as parking garages, unless a CO monitoring system is installed.

When carbon monoxide achieves and sustains pre-selected levels, successive alert indicator lamps, an alert relay and an internal alarm will activate.  The relay can be used to control remote indicators, fans or damper actuators.
