 a) At least one gas generator ( 3 ;  20 ;  30 ;  40 ;  50 ;  109 ;  120 ;  130 ;  139 ;  158 ) arranged decentrally is activated by a central monitoring device,    b) The gas generator ( 3 ;  20 ;  30 ;  40 ;  50 ;  109 ;  120 ;  130 ;  139 ;  158 ) in this situation generates a gas, for preference a smoke gas ( 12 ;  25 ;  37 ;  46 ;  57 ;  81 ;  104 ;  114 ;  128 ;  132 ;  149 ),    c) The gas detector ( 4 ;  100 ;  115 ;  121 ) detects the smoke gas ( 12 ;  25 ;  37 ;  46 ;  57 ;  81 ;  104 ;  114 ;  128 ;  132 ;  149 ), and the gas detector ( 4 ;  100 ;  115 ;  121 ) is thereby activated, and    the gas detector ( 4 ;  100 ;  115 ;  121 ) transmits a data signal.    
     
     
         57 . The method according to  claim 56 , characterised in that the gas detector ( 4 ;  100 ;  115 ;  121 ) transits the data signal to the central monitoring device and/or to an emergency facility.  
     
     
         58 . The method according to one of claims  56  or  57 , characterised in that the emergency facility is provided before the test with information about the pending test.  
     
     
         59 . The method according to one of  claims 56  to  58 , characterised in that at least one data line between the central monitoring facility and the emergency facility and/or at least one signal line between at least one gas detector ( 4 ;  100 ;  115 ;  121 ) and the emergency facility is deactivated.  
     
     
         60 . The method according to one of  claims 56  to  59 , characterised in that the emergency facility is sent a test report.  
     
     
         61 . The method for testing a smoke gas detector ( 4 ;  100 ; 115; 121), in which a smoke gas generator ( 3 ;  20 ;  30 ;  40 ;  50 ;  109 ;  120 ;  130 ;  139 ;  158 ) arranged in the vicinity of the smoke gas detector ( 4 ;  100 ;  115 ;  121 ) generates a smoke gas ( 12 ;  25 ;  37 ;  46 ;  57 ;  81 ;  104 ;  114 ;  128 ;  132 ;  149 ) by means of a test medium, and in which the smoke gas ( 12 ;  25 ;  37 ;  46 ;  57 ;  81 ;  104 ;  114 ;  128 ;  132 ;  149 ) initiates a test of the smoke gas detector ( 4 ;  100 ;  115 ;  121 ), characterised in that the test medium is evaporated into smoke by means of an electrical heating device ( 64 ;  75 ;  85 ) and the smoke gas ( 12 ;  25 ;  37 ;  46 ;  57 ;  81 ;  104 ;  114 ;  128 ;  132 ;  149 ) is conveyed by an electrical blower unit ( 59 ;  65 ;  102 ;  110 ) to the smoke gas detector ( 4 ;  100 ;  115 ;  121 ), and after the test of the smoke gas detector ( 4 ;  100 ;  115 ;  121 ) is vented by means of the blower unit ( 59 ;  65 ;  102 ;  110 ).
