Carbon Monoxide and Parking Garage Ventilation Systems

The CO sensors can go out of calibration, rendering the system ineffective and cause a harmful environment for occupants. Additionally, some sensors can’t read CO levels below a certain temperature. If a garage ventilation system is designed in a colder climate, there should be a built-in response to low temperatures that will override the exhaust fan to run at constant speed if the sensors ...
