2" Vxd Ptr Single Interlock Preaction Electric Release, Monitored

The Viking 2" VXD PTR Single Interlock Preaction Electric Release, Monitored system is an advanced fire protection solution designed to safeguard critical environments where accidental water discharge could cause significant damage. This pre-assembled, ready-to-install system combines the quick response of a wet pipe system with the added security of a dry pipe configuration, making it ideal for protecting water-sensitive assets like data centers, museums, libraries, and facilities with sensitive electronic equipment.

• 2" VXD Deluge Valve: At the core of the system is the Viking Model VXD Deluge Valve, a robust component that holds water back from the system piping until a fire event is confirmed.
• Single Interlock Preaction Technology: This system requires two independent events to occur before water is released into the sprinkler piping. First, an approved fire detection system (such as smoke or heat detectors) must activate. Second, an individual sprinkler head must activate from heat before water is discharged into the protected space.
• Electric Release Mechanism: The system utilizes an electric solenoid valve, controlled by a separate release control panel and compatible detection system. When the detection system senses a fire, it energizes the solenoid valve, initiating the deluge valve to open and fill the pipes with water.
• Monitored Solenoid: This version includes a monitored release solenoid, providing continuous oversight of the electrical release mechanism to ensure NFPA 13 compliance and enhanced reliability.
• Pneumatic Supervision: The sprinkler piping is supervised with pressurized air or nitrogen. A reduction in this supervisory pressure triggers a "low air" alarm, providing an early warning of potential leaks or damage to the piping before water is introduced.
• Pre-Trimmed Riser (PTR) Assembly: The system comes as a factory-assembled, pre-trimmed riser package, including the VXD deluge valve with trim, a riser check valve, an electric release solenoid, pressure gauges, and a complete drain manifold. This "plug-and-play" configuration simplifies installation.
• Durable Construction: Available with galvanized components, providing superior corrosion resistance for long-term system integrity in various environments.

The Viking VXD Single Interlock Preaction system provides peace of mind by minimizing the risk of accidental water damage, which is crucial for facilities housing invaluable items or sensitive equipment. Its dual-activation requirement ensures that water is only introduced into the piping after a fire is confirmed by an independent detection system, effectively preventing unintended discharges due to accidental pipe breaches or mechanical failure. The pneumatic supervision feature offers early leak detection, allowing for proactive maintenance and preventing unexpected system compromises. Being UL Listed and FM Approved, this system meets rigorous operational standards for critical fire protection infrastructure.
