Definitions

  • the invention relates to an alarm system, a system comprising an alarm system and such an alarm system, and a method for operating such an alarm system.
  • a large number of systems are known from the prior art, with which an alarm can be triggered in the event of an emergency situation, for example a fire, in a building.
  • Such systems are, in particular, hazard warning systems, which generally include sensors, for example smoke detectors, and alarm signal generators for outputting an optical or acoustic alarm signal.
  • hazard warning systems which generally include sensors, for example smoke detectors, and alarm signal generators for outputting an optical or acoustic alarm signal.
  • fire alarm systems are known for detecting fires, comprising a number of smoke detectors distributed in the building, an alarm trigger, an alarm signal generator and a fire alarm control panel (BMZ) for controlling the system.
  • BMZ fire alarm control panel
  • the components of the fire alarm system can be arranged in a loop, which forms a communication bus, so that if a fire is detected by one of the smoke detectors, an alarm activation signal is generated by the control panel and transmitted to the individual alarm signalers via the loop, as a result of which the alarm signalers emit an alarm signal.
  • the alarm activation signal in such hazard or fire alarm systems is usually based on a data protocol which activates and deactivates the alarm signal generator.
  • the supply voltage is also supplied via the loop.
  • the alarm signal generator and the loop are designed to operate with low voltages and currents, which limits their performance. As a result, only small rooms or areas can be signaled with such systems.

  • the invention is based on the object of providing an alarm system which has an extended functionality and which enables simplified servicing and maintenance.
