Alarm Input/Output

If the MX-ONE is equipped with an optional alarm board (known as ALU1 or ALU2 boards), then alarms in the alarm log can trigger alarm outputs on the board(s), and alarm inputs on the board(s) can raise alarms in the alarm log of the MX-ONE.

Alarm inputs are also available on the MGU. The MGU alarm inputs behave and are used as the ALU alarm inputs with the following minor differences:

• The MGU alarm inputs are polled, and will have a noticeable delay (of some seconds) compared to the interrupt driven ALU alarm inputs.
• An ALU alarm input can be defined as “Serviceman present”, which is not possible for the MGU alarm inputs.

This is done by the command alarm_input and the command alarm_output.
