The pneumatic control device is installed standing on the floor and fastened to a wall using a
wall bracket set. The pneumatic control device is activated by an electrical release device.
When activated, a release pin is activated in the electric release device. The release pin opens
the pilot cylinder valve. The control gas then flows through the pressure reducer into the con-
nected pneumatic pilot line to the pneumatic system parts of the fire extinguishing system.
