Abstract: A sprinkler system comprises at least one double interlock pre-action head that has a conduit having an inlet and outlet to permit flow of fire suppressant fluid through the conduit. A dedicated electrically actuatable valve is connected to the conduit to prevent fire suppressant fluid in sprinkler system piping from entering the conduit.
