General lot line is directly installed to the Model DDX Deluge Valve’s pushrod chamber. Wet pilot line sprinklers are detection devices and do not provide any water to aid in the firefighting capability of the fire sprinkler system. To fully operate a Wet Pilot Line Single Interlock Preaction System, the heat from a fire must fuse a wet pilot line sprinkler/detector thereby releasing the water pressure from the Deluge Valve’s pushrod chamber.
a second, nearby or adjacent, detector will cause the panel to energize the solenoid valve open and release water into the sprinkler system piping. Water flowing into the sprinkler system piping will simultaneously produce water pressure that causes the transfer of contacts in the pressure switch mounted in the Reliable Single Interlock Preaction System’s riser assembly. This pressure switch can electrically initiate the shut down or startup of equipment, such as computers or other second alarm devices.

System Operation In all Reliable Single Interlock Preaction Systems, once the clapper has opened, the lever acts as a latch, preventing the clapper from returning to the closed position. Water from the supply flows through the Deluge Valve into the system piping. Water also flows through the Deluge Valve alarm outlet to the alarm devices. After system shutdown, resetting the Model DDX Deluge Valve is quite simple.

Pressurizing Line Connection System Design Considerations The water supply for the push-rod chamber must be provided by connection of its inlet pressurizing line to the water supply piping. Pressurizing lines for multiple Model DDX Deluge Valve push-rod chambers must never be manifolded together, having only a single tap on the water supply piping. Each Model DDX Deluge Valve must have its own push-rod chamber pressurizing line connection.
System Air Pressure Requirements For Wet Pilot Single Interlock Preaction Systems and Electric Actuation Single Interlock Preaction Systems, a Reliable Model B-SI Air Compressor Panel or Reliable Model C-SI Air Compressor Panel can be used to maintain the system air pressure at approximately 7 psi (0,5 bar). The air compressor panels contain an integral low air pressure warning light.

area to be protected. This pressurized line is connected to a Model LP Dry Pilot Line Actuator. The dry pilot line actuator functions very much like a miniature dry pipe valve. In areas where moisture-laden air could cause freezing or other problems in the dry pilot line, the use of a cylinder of dry compressed gas such as nitrogen is suggested. Approved gas handling regulators and connections are then recommended.
