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.\u003c\/p\u003e\n\n\n\u003cp\u003e• SKU: AS-4\u003cbr\u003e\n• Brand: TrolMaster\u003cbr\u003e\n• System Compatibility: TrolMaster Carbon-X CDA-1\u003cbr\u003e\n• Alarm Type: Audible + blue LED visual strobe\u003cbr\u003e\n• Display: LCD digital CO₂ ppm readout\u003cbr\u003e\n• Sensor Channel Linkage: AL-1, AL-2, or both for dual-channel redundancy\u003cbr\u003e\n• Connection: RJ12\u003cbr\u003e\n• Power Requirement: SPH-1 Splitter Hub required for power over RJ12\u003cbr\u003e\n• Included Cable: 16-ft RJ12 cable\u003cbr\u003e\n• Operating Temperature: 32–122°F (0–50°C)\u003cbr\u003e\n• Operating Humidity: ≤90% RH, non-condensing\u003cbr\u003e\n• Package Dimensions: 130 × 187 × 88 mm\u003cbr\u003e\n• CO₂ Reading: Live ppm displayed continuously\u003cbr\u003e\n• Alarm Activation: Blue LED flashes and audible alarm activates when the CDA-1 configured threshold is exceeded\u003cbr\u003e\n• Mounting Location: Outside the monitored room, corridor, hallway, or above entry doors\u003cbr\u003e\n• Standalone Operation: No — requires Carbon-X CDA-1\u003cbr\u003e\n• Warranty: 3-year manufacturer warranty\u003c\/p\u003e\n\n\n\u003cp\u003eKey Advantage: The AS-4 provides three layers of CO₂ awareness in one station—continuous ppm display, blue visual strobe, and audible alarm.
