Carbon monoxide detector - Wikipedia

System-connected detectors, which can be wired to either a security or fire panel, are monitored by a central station. In case the residence is empty, the residents are sleeping or occupants are already suffering from the effects of CO, the central station can be alerted to the high concentrations of CO gas and can send the proper authorities to investigate. The gas sensors in CO alarms have a ...

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 ...
