In such an apparatus the risk of leaks occurring is reduced and effective alarming of the surroundings at the beginning of the fire-extinguishing process is ensured according to the invention by the fact that the alarm device (5) comprises a pressure-actuatable switching device connected to the pipe (2) which triggers the warning signal in the event of an increase in the pressure prevailing in the pipe (2).
