 <<  |  <  | OVERVIEW | SPECIFICATION | DATASHEETS        

The AX-GS-CM-BN can detect hazardous carbon monoxide emissions in parking garages, warehouses, and other similar environments. It uses an electrochemical sensor to monitor carbon monoxide (CO) concentration levels ranging from 0 to 300 parts per million (ppm). The device transmits data over the RS-485 network using the BACnet MS/TP protocol. By continuously monitoring CO levels, the ventilation system can be adjusted accordingly to maintain air quality within safe limits.
