摘要： Various embodiments include a method for operating a hazard notification system including a plurality of notification appliances connected to a bus system, each notification appliance having a signal element and an activatable energy consumption simulation unit comprising: receiving a switchover telegram at each notification appliance; attaching the respective energy consumption simulation unit of each notification appliance to the bus system in place of the signal element; measuring an energy consumption resulting in the bus system due to the activation of each energy consumption simulation unit in the course of a load test; comparing the measured energy consumption with predefined comparison values; and generating an alarm signal or a fault message as a function of the result of the comparison.

摘要： 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.
