Parking Garages and Carbon Monoxide Gas Detection Sensors ...

That is, when the sensor is contacted by carbon monoxide (CO) or nitrogen dioxide (NO2) a change in voltage happens which triggers the fan to activate. As the sensor is contacted by gas over months or years, these chemicals begin to wear out and they no longer trigger the fan at the proper concentration of hazardous gases. For that reason, the manufacturer’s require that the sensors be ...

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 ...
