Viking FSX-A Deluge Systems utilize a Viking Model FSX-A Deluge Valve to control the water supply to system piping equipped with open sprinklers and/or spray nozzles.

The system piping remains empty until the deluge valve is activated by operation of the release system. Deluge systems are commonly used where it is desirable to simultaneously spray water from all open sprinklers and/or nozzles on the system when it operates.

Deluge systems with electric release require an electric solenoid valve controlled by an approved system release control panel with compatible detection system.

Deluge systems with hydraulic release uses a pilot line that is directly connected to the control chamber of the deluge valve. The system pressure of the water supply is permanently applied to the pilot line. When a pilot sprinkler is activated, the pilot line pressure and deluge control chamber pressure drops which opens the valve.

In fire conditions, when the detection system operates, the system release control panel energizes solenoid valve open, causing the deluge valve to open and allowing water to enter the system piping. Water will flow from any open sprinklers and/or spray nozzles on the system.

In case of a power failure, the Pilot Operated Relief Valve ensures that the system continues to operate.

The FSX-A Deluge System is UL Listed and FM Approved.
