1. INTRODUCTION
Viking supervised VXD Single-Interlocked Preaction Systems utilize a Viking
Model VXD Deluge Valve and a pneumatically pressurized automatic sprinkler
system. This feature helps prevent undetected leaks. Single-Interlocked Preaction
Systems are commonly used where the sprinkler system piping and/or sprinkler
may be subject to damage. If the system piping or a sprinkler is damaged,
supervisory pressure is reduced and a "low air" supervisory is activated. The
electrically controlled preaction systems include an electric solenoid valve
controlled by an approved release control panel (sold separately) with compatible
detection system (sold separately). In fire conditions, when the detection system
operates, the system release control panel energizes the solenoid valve open,
causing the deluge valve to open. The sprinkler system fills with water. If any
sprinklers have opened, water will flow from the system. If sprinklers have not
opened, water will be in the sprinkler system piping when the sprinkler operates.
A sprinkler must open before water flows from the system.
