A CO2 monitoring system in Colorado Springs that meets Section 5307
Section 5307 of the 2021 code covers CO2 systems. Indoor CO2 storage needs ventilation or gas detection. Enrichment systems over 100 pounds need sensors within 12 inches of the floor, a 5,000 ppm low alarm, a 30,000 ppm high alarm and an automatic stop to the supply.
A CO2 monitoring system in Colorado Springs that an inspector signs off is therefore a sensor, an alarm and a shutoff wired together, not a box on the wall. We leave documentation showing what is installed and at what thresholds.
