System Data at Your Fingertips
An advanced vent controller provides automatic oxygen venting and monitoring of nitrogen/oxygen concentration levels within each dry/preaction fire sprinkler system. Tyco offers two models: the TVC-2 and the TVC-6. One TVC-2 can control and monitor up to two (2) separate fire sprinkler systems, while the TVC-6 works with up to six (6) systems. The system can be easily monitored via the Human Machine Interface (HMI) display. The screen allows easy access to operation, maintenance, diagnostics and stored historical data.
Benefits
Reduced Equipment Footprint
Unique technology eliminates the need for a nitrogen tank or refrigerated air dryer.
No Remote Equipment
Install the vent directly on the riser — no vents are needed at far points of the system.
Minimize Business Interruption
System leaks due to corrosion can lead to costly downtime — reducing corrosion helps keep systems healthy and operational.
Data At Your Fingertips
Instant access to historical data simplifies diagnostics to help keep systems operational.
