<p>The system has a fire detection unit (2-A) measuring an electrical magnitude e.g. resistance, between terminals (B0-A-B1-A). A detector is connected to the terminals and provides a value of the electrical magnitude in a determined state of the detector, where the state corresponds to the detection of fire. Another detector is connected to the terminals and forms another value of the electrical magnitude in the determined state, where the two values are different from each other.</p> |
