About PREACTION-PAC™ with Integrated Nitrogen

All components are contained in three (3) red powdercoated steel enclosures. Preaction and nitrogen system indicators and controls are mounted facing forward for easy reference and use. The system detection and control panel is mounted behind a door on the electrical enclosure with a clear polycarbonate window allowing examination of the detection system visual indicators. Lockable latches on enclosure doors permit restricted access to connections and components. A manual release valve is located behind a non-locking door on the valve enclosure. Gasketing provides sealing of the enclosure doors. Knockouts permit easy attachment of external electrical raceways.

Did You Know?
  • Your wet-pipe sprinkler system may not be as filled with water as you expect it to be. A bubble of air may migrate to the highest point in the system, creating a very vulnerable location for internal pipe corrosion. That’s why NFPA 13 now requires that all new wet sprinkler systems be fitted with an air vent at the system’s highest point. This is a good investment for both new and existing systems. The UNITED Fire Systems Model AR-1 automatic air vent device is Factory Mutual (FM) Approved for just this function. See here for more information, and take action to prevent damaging corrosion.
