FC A Basic Alarms Practice Test

Which term describes a fault condition that could affect operation, such as loss of power or communication failure?

Normal Supervisory Trouble Alarm

Correct Answer:

Trouble

Explanation:

Trouble signals a fault condition that could affect operation. It covers situations where something isn’t right and could impair performance, such as loss of power or loss of communication. This is more serious than supervisory, which means a condition should be monitored but isn’t yet affecting operation. It’s not an active alarm, which would require immediate action for a fault currently impacting the system. Normal means everything is functioning normally. In practice, labeling a condition as trouble helps operators recognize an issue that could degrade performance and needs attention before it escalates.
