Viking EA-1 VXR Galvanized Dry Pipe System for Cold Areas

water suppression in under four seconds. Engineered to satisfy stringent life safety regulations, this assembly adheres to NFPA 13 installation requirements for dry pipe fire protection systems. It integrates with the Viking Model VXR Dry Pipe Valve, relying on a differential air-to-water seat design to maintain a complete separation between water supplies and pressurized piping until system activation occurs. Key Features & Construction Galvanized Construction: Features a durable zinc coating on all system trim components and fittings to resist rust and corrosion in demanding environments. EA-1 Electronic Accelerator: Monitors air or nitrogen pressure twice per second, cutting response times to under four seconds during a pressure drop. CoilKeeper Supervisory Switch: Continuously monitors the solenoid coil position to detect removed, open, or shorted coils and prevent accidental discharge. Advanced Monitoring: Tracks air pressure and system status in real time, delivering early warning alerts for abnormal conditions like a 10 PSI pressure drop. Complete Trim Package: Ships ready to install with the EA-1 device, CoilKeeper switch, and all necessary trim components. Unimpeded Flow: Smooth internal surfaces on the galvanized steel components ensure unrestricted water delivery during an emergency.
