Double Interlock - Electric/Electric Actuation
The Tyco Model DV-5 Double Interlock Preaction System with Electric/ Electric Actuation is designed for use in applications, such as refrigerated areas, requiring the maximum degree of protection against inadvertent flooding of the sprinkler system piping.
The Model DV-5 Double Interlock Preaction System with Electric/Electric Actuation utilizes a Model DV-5 Deluge Valve and a Riser Check Valve. The Riser Check Valve isolates the Deluge Valve from the system air pressure. The releasing trim for the Deluge Valve utilizes a Solenoid Valve that is operated by energizing the releasing circuit of a Cross-Zone Deluge Valve Releasing Panel.
