1. A method for automatic identification of fire detectors in a fire alarm system of a building, wherein the fire alarm system includes a plurality of fire detectors, a panel, and a transmission line, the method comprising:
determining linear distance spacings between respective fire detectors based on a floor plan;
determining line distances between respective fire detectors by measurement along the transmission line and using the line distances to determine a fire detector sequence;
creating a graph using the linear distance spacings and the line distances with a set of potential connection orders;
wherein the fire detector sequence and the potential connection orders comprise designations, which in each case reference a fire detector connected to the transmission line or a fire detector provided according to the floor plan data;
determining a potential connection order matching the fire detector sequence based on the set of potential connection orders;
determining, as a result of the potential connection orders determined as matching, a correspondence of the designations included in the fire detector sequence on the one hand and the connection order determined on the other hand in their order within the fire detector sequence or the connection order determined results;
wherein the correspondence represents the identification of the fire detectors;
generating an electronic record including a respective serial number, a respective physical location corresponding to the floor plan, and a respective network address for each fire detector; and
storing the electronic record for use in operating the fire alarm system.
