2.2.1 Infeed Cut-Out
The device IRM is equipped with a cut‑out for an easier disconnection of the device.
The disconnection of the supply circuit does not prevent the normal operation of the series
circuit.
2.2.2 Voltage measuring on the series circuit
The device IRM can provide the reading of the actual voltage value on the series circuit. The voltage value is locally
available and is communicated to the cabin supervision system.
2.2.3 Remote signalling
The device IRM can be equipped with a signalling system of electromechanical remote signalling of the anomalies:
FAULT, WARNING and ERROR.
For each type of anomaly detected is made available a dry reverse contact (NC+NO).
