Alarm LEDs and Alarm Cutoff Button

Two large alarm LEDs are located at the upper right of the craft interface. The circular LED called major
alarm LED glows to indicate a critical condition that can result in a system shutdown. The triangular LED
called minor alarm LED glows to indicate a less severe condition (warning) that requires monitoring or
maintenance. Both LEDs can be lit simultaneously.
A condition that causes an LED to be lit also activates the corresponding alarm relay contact on the craft
interface.
