7. The admixing system according to claim 1 , wherein

at least one extinguishing agent additive pump ( 34 p 1 , 34 p 2 , 34 p 3 ) is assigned to each extinguishing agent additive line ( 36 ), and

the at least one extinguishing agent additive pump ( 34 p 1 , 34 p 2 , 34 p 3 ) pumps a fixed quantity of extinguishing agent additive ( 32 ) into the particular extinguishing agent additive line ( 36 ).

8. An extinguishing or watering system ( 200 ), having

at least one admixing system ( 100 ) according to claim 1 ,

at least one extinguishing agent container ( 20 ) for storing the extinguishing agent ( 22 ),

at least one extinguishing agent pump ( 24 ), which is connected to each of the watering or sprinkler units ( 10 ) respectively via at least one extinguishing agent line ( 26 ), and

at least one extinguishing agent additive container ( 30 ) for storing the extinguishing agent additive ( 32 ).

9. The extinguishing or watering system according to claim 8 , wherein

the extinguishing agent additive container ( 30 ) is connected to the extinguishing agent additive lines ( 36 ) via at least one extinguishing agent additive return line ( 38 ) and

the extinguishing agent additive ( 32 ) may be returned into the extinguishing agent additive container ( 30 ) via the extinguishing agent additive return line ( 38 ).

10. The extinguishing or watering system according to claim 9 , wherein the extinguishing agent additive lines ( 36 ) have at least one unit ( 40 p 1 , 40 p 2 , 40 p 3 ) which returns the extinguishing agent additive ( 32 ) into the extinguishing agent additive container ( 30 ) via the extinguishing agent additive return line ( 38 ) if a limiting or delivery pressure is exceeded.

11. The extinguishing or watering system according to claim 10 , wherein the unit ( 40 p 1 , 40 p 2 , 40 p 3 ) which returns the extinguishing agent additive is a pressure limiter.
