Viking VXD Electric/Pneu-Lectric Double Interlocked Preaction Systems utilize a Viking deluge valve, pneumatic supervision of the automatic sprinkler system, and an electric detection system. The deluge valve release trim utilizes a normally closed electric solenoid valve controlled by an approved release control panel with two initiating circuits configured for “cross-zoned” operation. One initiating circuit is connected to the electric detection system; the other to a “low-air” supervisory switch.

Viking’s Valve and System Configurator allows users to save time while building a system riser digitally, while generating a complete system and materials list for project needs.
