At least some of the plurality of remote units including an indicating device for modulating a current in the circuit. The plurality of remote units are in communication with the fire panel in a master-slave relationship. The fire panel includes a calibration module for polling each indicating device to obtain a current response value and for storing said current response values, the current response value of an indicating device being based on the amplitude of the current when modulated by that indicating device.
