Abstract: 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.

Abstract: The teachings of the present disclosure relate to bus systems. Various embodiments thereof may include bus coupling units, for example a bus coupler comprising: four ports comprising input/output connections to which bus cables of a two-wire bus are connectable, wherein both electrical energy and data are transmissible via both bus cables. The first port and second port are bus coupler-internally electrically conductively connectable by means of a first connection path. The third port and fourth port are bus coupler-internally electrically conductively connectable by means of a second connection path. The first connection path and second connection path are bus coupler-internally electrically conductively connectable by a bridge path.

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 bipole is fitted in a warning system socket for removably receiving a hazard warning system in order to set one of at least two operating modes of the hazard warning system. An electric characteristic of the bipole can be read out electrically by an electronic control of the hazard warning system via two electric contact pairs which are in contact with each other in the received state of the hazard warning system. In particular, the bipole is used via at least one pair of electric contacts, the pair being generally provided for externally connecting an optical and/or acoustic alarm emitter, in order to read in the electric characteristic of the bipole. The bipole is preferably a passive electric resistor.

Abstract: The interface has three inputs, a first output which is connected to a first input, a second output which can be connected to a second input or to the third input. The interface also includes a switching device which is connected to the second input, the third input and the second output, and a control device which is coupled to the third input in such a way that a detection signal can be fed from the third input to the control device. The detection signal is indicative of whether the second input or the third input is connected to the second pole of the two-pole line.

Abstract: A danger warning system has a central station and appliances which are connected thereto by a monitoring line. Each appliance has an insulator switch, an unequivocal identification number, and a communication address. In order to determine the configuration of the danger warning system, the appliances that can be decoupled by the insulator switch are sequentially started and announced to the central station. In the event of simultaneous announcements of more than one appliance, only the announcement of one of said appliances is accepted. During the announcement of appliances at the central station with the communication addresses thereof, when appliances with different communication addresses are simultaneous announced, the communication addresses are differed according to an arbitration method, and the two different communication addresses are sequentially registered.

Abstract: A radio communication system has a central station, at least one slave radio station), a first gateway, and a second gateway. The slave radio station is coupled to the central station by way of a first transfer path using the first gateway and by way of a second transfer path using the second gateway. A method is detailed that provides for transferring data between a slave radio station and a central station of a radio communication system.

Abstract: In order to determine the position of a device newly introduced into a hazard detection system, the devices of which include an insulator and are connected to a control center by a warning line, the newly introduced device is interrogated multiple times from one side of the warning line. The insulator of a device with an already known topology is first opened, subdividing the warning line into two branches, and the branch wherein the newly introduced device is located is then determined. This interval halving process is repeated until the exact position of the newly introduced device is found. In its preferred implementation, the device is a hazard detector or an actuator.
