The TrolMaster AS-4 is an audible-visual CO₂ alarm station for the Carbon-X CDA-1 safety and monitoring system. It combines a blue LED strobe, audible alarm, and continuously displayed live CO₂ ppm reading so personnel outside a monitored grow room can immediately assess atmospheric CO₂ conditions. The station connects through RJ12 and is designed to be mounted outside the monitored space, such as on corridor walls, above entry doors, or in adjacent hallways.

Key Advantage: The AS-4 provides three layers of CO₂ awareness in one station—continuous ppm display, blue visual strobe, and audible alarm. It can also be linked to both Carbon-X sensor channels for redundancy, while the blue indicator distinguishes it from the orange AS-3 version for installations where a specific alarm color is required.
