1. A method for operating a fire alarm system with a plurality of fire detectors connected via a common transmission line to a panel, the method comprising:
sending a stimulus from the panel to each fire detector to trigger the respective fire detector;
sending a message from each fire detector to the panel in response to the stimulus;
processing the message at the panel to trigger a reaction of the panel;
wherein a test of the fire alarm system includes triggering a first set of the plurality fire detectors
in two separate modes, first in a recording mode and later in a test mode, wherein the test mode is carried out after a firmware update of the panel;
wherein in recording mode, for each fire detector in the first set, the resulting reaction of the panel is stored in the panel;
after conducting the test mode, for each fire detector in the first set, comparing
the respective stored reaction and the resulting test mode reaction; and
generating an error message at the panel if no match or no sufficient match is determined during the comparison.
