1. A method for extinguishing objects or devices, comprising the following method steps preferably carried out in succession:

  • (a) detecting a first fire signal by at least one event detector (11) and at least one of a fire alarm or an extinguishing control panel (12), at the time t1,(b) actuating a first extinguishing agent supply device (17) by the at least one of a fire alarm or an extinguishing control panel (12) for discharging a liquid synthetic extinguishing agent (14) by way of a common pipe (9) and at least one nozzle (10),(c) detecting a second fire signal at the time t2 and(d) actuating a second extinguishing agent supply device (18) and delivering one of a water (3) or a water-based extinguishing agent via the common pipe (9) and at least one nozzle (10) for extinguishing purposes,wherein the discharge of the liquid synthetic extinguishing agent (14) and the delivery of the water (3) or the water-based extinguishing agent is carried out by a separation apparatus (8) and wherein, furthermore, there is an actuation of the separation apparatus (8) by the at least one of a fire alarm or an extinguishing control panel (12), prior to method step (b), for generating a switching position, which releases a transport path of the liquid synthetic extinguishing agent (14) in the direction of the common pipe (9) and the at least one nozzle (10) and completely blocks the transport path of the one of a water (3) or the water-based extinguishing agent from the second extinguishing agent supply device (18) in the direction of the common pipe (9) and the at least one nozzle (10) and there is an actuation of the separation apparatus (8) by the at least one of a fire alarm or an extinguishing agent control panel (12), prior to method step (d), for generating a switching position of the separation apparatus (8) which releases the transport path of the at least one of a water or the water-based extinguishing agent (3) in the direction of the common pipe (9) and the at least one nozzle (10) and completely blocks the transport path of the liquid synthetic extinguishing agent (14) from the first extinguishing agent supply device (17) in the direction of the common pipe (9) and the at least one nozzle (10).
