| Zusammenfassung: | The invention relates to an alarm system for protecting a building, or individual rooms in a building, in which the switching device is not accommodated in a separate housing separated from the warning signal housing, but inside the warning signal housing, so that the installation is drastically simplified and the risk of unauthorised neutralisation of the alarm system is greatly reduced. In the case of wireless transmission of signals from the individual signal transmitters to the switching device, or in the case of transmission using the building power network, a mains lead is provided as the single supply lead, which, in particular, is not accessible from the exterior when the warning signal housing is fitted on an external wall and thus also cannot be separated. |
