What failure message is displayed for a sensor failure?

Explanation:
The key idea here is how alarms should clearly convey a fault condition. The sensor-fault message should be unambiguous and directly indicate that the sensor is not functioning. SENSOR FAIL does exactly that: it states plainly that the sensor has failed, prompting the proper fault-handling response. The other options introduce ambiguity or shorthand that can be misread: SENSOR ERROR could imply a data issue rather than a hard hardware failure, SNR FAIL and SNR ALERT use an abbreviation that isn’t a standard sensor-fault label and can confuse the user. For immediate, decisive action in safety-critical contexts, SENSOR FAIL is the clear, appropriate display.
