Abstract
In various embodiments, an alarm handling circuitry is provided. The alarm handling circuitry may include a first alarm processing circuit configured to process a first received alarm and to provide a first processed alarm response signal, a second alarm processing circuit configured to process a second received alarm and to provide a second processed alarm response signal, and an interface between the first alarm processing circuit and the second alarm processing circuit configured to input an alive indication signal from the first alarm processing circuit to the second alarm processing circuit indicating whether the first alarm processing circuit is operating.
Claims20
An alarm handling circuitry, comprising:
- a first alarm processing circuit configured to process a first received alarm and to provide a first processed alarm response signal;
- a second alarm processing circuit configured to process a second received alarm and to provide a second processed alarm response signal;
- and
- an interface between the first alarm processing circuit and the second alarm processing circuit configured to input an alive indication signal from the first alarm processing circuit to the second alarm processing circuit in a case of the first alarm processing circuit operating correctly, wherein an absence of the alive indication signal is a representation of the second received alarm.

A method of handling alarms, comprising:
- providing a first processed alarm response signal by processing a first received alarm using a first alarm processing circuit;
- providing a second processed alarm response signal by processing a second received alarm using a second alarm processing circuit;
- transmitting an alive indication signal from the first alarm processing circuit to the second alarm processing circuit when the first alarm processing circuit is operating correctly, wherein an absence of the alive indication signal is a representation of the second received alarm.
An alarm handling circuitry, comprising:
- an alarm processing circuit configured to process a received alarm and to provide a processed alarm response signal;
- a first monitoring circuit configured to determine whether the alarm processing circuit operates by processing the received alarm and providing the processed alarm response signal;
- and
- a second monitoring circuit configured to determine at least one of a plurality of different types of failure of the alarm processing circuit,
- wherein the first monitoring circuit comprises:
- an alarm existence determination circuit configured to determine whether the alarm has been received and configured to determine whether the processed alarm response signal is provided;
- and
- a response provision determination circuit configured to determine whether the processed alarm response signal is provided in case it has been determined that the alarm has been received and configured to determine whether the alarm has been received in case it has been determined that the processed alarm response signal has been provided;
- wherein the first monitoring circuit is configured to determine that the alarm processing circuit operates if the alarm has been received and the processed alarm response signal is provided and to determine that the alarm processing circuit does not operate if the alarm has been received and the processed alarm response signal is not provided, or if the processed alarm response signal is provided, even though the alarm has not been received.

A method of handling an alarm, comprising:
- providing a processed alarm response signal by processing a received alarm using an alarm processing circuit;
- determining, using a first monitoring circuit, whether the alarm processing circuit operates by processing the received alarm and providing the processed alarm response signal;
- determining, using a second monitoring circuit, at least one of a plurality of different types of failure of the alarm processing circuit,
- wherein the determining whether the alarm processing circuit operates comprises:
- determining whether the alarm has been received using an alarm existence determination circuit;
- determining, using a response provision determination circuit, whether the processed alarm response signal is provided in case it has been determined that the alarm has been received and whether the alarm has been received in case it has been determined that the processed alarm response signal has been provided;
- and
- wherein the first monitoring circuit is configured to determine that the alarm processing circuit operates if the alarm has been received and the processed alarm response signal is provided and to determine that the alarm processing circuit does not operate if the alarm has been received and the processed alarm response signal is not provided, or if the processed alarm response signal is provided, even though the alarm has not been received.
