Viking Model F-1 – Double Interlock Preaction System (Electric / Pneu-Lectric Release)

This model combines an electric release with a pneu-lectric release, which is a hybrid mechanism utilizing both electrical activation and pressure-based mechanical release. The system provides high flexibility under field conditions, enhanced redundancy, and keeps the piping dry until both activation conditions are met.

Key Features

  • Combination of Electric + Pneu-Lectric Release

  • High redundancy for critical environments

  • Multi-release design minimizes the risk of system failure

  • Ideal for areas requiring reliability greater than 99%

  • Piping remains dry until both conditions are fulfilled

  • UL & FM approved
