- Double Interlock - Electric/Pneumatic Actuation
- The Model DV-5 Double Interlock Preaction System with Electric/Pneumatic 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/Pneumatic 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 and a Dry Pilot Actuator in a series configuration. The system air pressure holds the Dry Plot Actuator closed, whereas the Solenoid Valve remains closed until it is electrically energized by a Deluge Valve Releasing Panel. The Releasing Panel is operated by either a fire detection device or manual electric pull station.

+ What is Proposition 65?
The purpose of Proposition 65 is to ensure the public is informed about the potential exposure to chemicals known to cause cancer,
birth defects, or other reproductive harm.
The law requires the State of California to publish a list of these chemicals.
This list currently contains ~1,000 chemicals; chemicals are added and removed regularly.
Johnson Controls products may have traces of various chemicals that are on the list,
however they are all a part of the normal manufacturing, distribution or labeling process.
