3.6 Manual Release (600055)
The manual release is used as an optional part of the system detection line network. The manual release is used to manually release the nitrogen
pressure in the tubing, causing the system to actuate. The actuation results in a complete discharge of the unit assembly.
The tube fitting on the body of the manual release allows for easy installation onto the system detection line network. The pull tab on the plunger
prevents accidental activation of the manual release. The port on the body of the manual release is used to pressurize the tubing and allows for
installation of a pressure gauge to monitor system pressure, refer to Figure 5 – Manual Release.
CAUTION: Do not remove the pull tab until ready to actuate system discharge
