What constitutes an "unwanted alarm"?

An "unwanted alarm" is defined as an alarm activation that occurs without any actual hazard condition present. These types of alarms are problematic because they can lead to alarm fatigue, where people start to disregard alarms due to frequent false alerts. Additionally, unwanted alarms can divert attention and resources away from actual emergencies, potentially compromising safety.

In this context, the choice indicating that an alarm occurs with no hazard condition accurately reflects the definition of an unwanted alarm. Unwanted alarms can arise from various sources, but their defining characteristic is the absence of a real threat or danger at the time of the alarm.
