Abstract: A hazard management system is provided with a field bus and a broadband bus. The field bus is configured to connect at least two units of the hazard management system for sending alarm signals among the units of a hazard management system. The broadband bus, which is separate from the field bus, is configured to connect at least two units of a hazard management system, so that these units may exchange data through the broadband bus. The broadband bus is configured to stream audio and/or video data from one unit to other units or to deploy software updates among the units of the hazard management system.

Abstract: A detector base for fixing to a mounting surface may include a connection for connecting to a detector line of a hazard alarm system and a first connection side for releasably attaching a hazard detector embodied as a point detector. The first connection side may be electrically and structurally co-ordinated with a second connection side of such a hazard detector, such that the latter is releasably attachable to the detector base and is indirectly connectable via the latter to the detector line. The detector base may include a radio device affixed to the detector base and serving for transmitting position data of the detector base mounting location and/or for transmitting a reference to a database having said position data. The radio device may be based on a Bluetooth low energy standard.

Abstract: A method determines a quality of a communication connection between a selected secondary station and a main station of a radio-operated multi-hop hazard reporting system. The method includes the determination of a value of a first parameter for the selected secondary station, the value of the first parameter is indicative of the connection security only between the selected secondary station and the main station. The method further includes a determination of a value of a second parameter for the selected secondary station, wherein the value of the second parameter is indicative of the connection security only between any directly adjacent secondary stations of the selected secondary stations and the main station, and a determination of the quality of the communication connection based only on the value of the first parameter and the value of the second parameter.
