The TrolMaster DSE-1 is an emergency CO₂ shutoff module designed for the Carbon-X CDA-1 safety system. It sits between the Carbon-X controller and a CO₂ solenoid valve, supplying power during normal operation but automatically cutting power whenever Carbon-X detects a high-CO₂ fault or loses communication with the controller. This fail-closed design ensures the connected solenoid valve closes rather than allowing CO₂ injection to continue during a system or communication failure.

• Included: 1× DSE-1 station, 1× 16-ft RJ12 cable, 1× 4-ft RJ12 cable, 1× RJ12 T-splitter
• Carbon-X Capacity: Counts as one output device toward the system's 40-output maximum
• Standalone Operation: No — requires Carbon-X CDA-1
Key Advantage: The DSE-1 provides a dedicated fail-closed emergency shutoff for each CO₂ supply line, automatically stopping CO₂ injection not only when an unsafe CO₂ level is detected, but also when the Carbon-X controller loses communication with the station. This makes it a safety-focused output module rather than a normal CO₂ control relay.
