The TrolMaster DCC-2 is a dual-system control adapter that allows one physical device to be controlled by two separate TrolMaster controllers simultaneously. Unlike the DCC-1, which allows two conditions within the same controller to operate one device, the DCC-2 is specifically designed for cross-controller integration—for example, allowing the same exhaust fan to respond to both Hydro-X climate conditions and Carbon-X CO₂ safety alarms. It connects to compatible plug-in device stations through its built-in RJ12 cable and requires no separate power supply.
• SKU: DCC-2
• Function: Connects one device to two independent TrolMaster controllers
• Controllers Supported: Up to 2 simultaneous controllers
• Compatible Systems: Hydro-X, Hydro-X Pro HCS-1/HCS-2 and Carbon-X
• Input Power: 12V DC / 0.2A
• Power Source: Powered through the TrolMaster RJ12 network
• Connection Type: RJ12 with built-in cable
• Compatible Modules: DSC-1, DSH-1/2, DST-1/2, DSP-1, DSD-1 and DSV-1
• Typical Applications: Exhaust fans, CO₂ valves, dehumidifiers, heaters and other compatible controlled devices
• Cross-System Control: Allows the same physical device to respond to different control authorities
• Example Application: Hydro-X controls an exhaust fan for temperature/RH while Carbon-X can independently activate the same fan during a CO₂ safety event
• Separate Power Supply: Not required
• Installation: Plug-and-play within the existing RJ12 network
• Operating Temperature: 32–122°F (0–50°C)
• Package Contents: 1× DCC-2 Dual System Control Adapter
• DCC-1 Difference: DCC-1 combines two conditions within one controller; DCC-2 connects one device to two separate controllers
Key Advantage: The DCC-2 lets two independent TrolMaster systems share one physical piece of equipment, eliminating the need for duplicate device stations or complicated relay workarounds. This is especially valuable when Hydro-X needs normal environmental control while Carbon-X must retain independent authority for emergency CO₂ ventilation.
