1. An extinguishing nozzle adapter for mounting an extinguishing nozzle on a wall, comprising:
a housing defining a chamber extending along a longitudinal axis, the housing having an extinguishing agent connection to the chamber and an interior wall disposed within the chamber;
an extinguishing nozzle received within the chamber;
a piston disposed within the chamber, the piston having a passage opening in fluid communication with the extinguishing nozzle; and
a spring disposed about the piston;
wherein via the extinguishing agent connection the chamber is able to be pressurized with extinguishing agent,
wherein the chamber is designed to receive the extinguishing nozzle in a movable manner such that the extinguishing nozzle is movable back and forth between a first, retracted position and a second, advanced position,
wherein, in the first, retracted position, the spring engages the piston and the interior wall so that the extinguishing nozzle abuts the interior wall,
wherein the extinguishing nozzle is moved in a direction of the second, advanced position when the chamber is pressurized by the extinguishing agent and is located at the second, advanced position when the piston engages a stop positioned within the chamber between the interior wall and the extinguishing agent connection,
wherein the chamber has an extinguishing nozzle side including an end enclosed by a cover, the extinguishing nozzle side of the chamber including a first form-fitting element including a first surface comprising a groove that cooperates with a second surface of a corresponding second form-fitting element comprising a protrusion protruding laterally from a head of the extinguishing nozzle and the first form-fitting element and the second form-fitting element are positioned between the interior wall and the cover to control an orientation of the extinguishing nozzle, and
wherein the housing includes a mounting flange for fastening the extinguishing nozzle adapter to the wall, the mounting flange having a marking that is representative of the orientation of the extinguishing nozzle inside the housing.
