What leads to an alarm being categorized as a nuisance?

The categorization of an alarm as a nuisance primarily stems from mechanical failures or improper installation. When a fire alarm system is not correctly installed or has components that malfunction, it can lead to frequent false alarms. These false alarms can cause unnecessary panic, disrupt building operations, and lead to alarm fatigue among the occupants and responders.

Proper maintenance of the fire alarm system typically ensures its reliability and reduces the likelihood of false alarms, making this option less likely to contribute to nuisances. Similarly, excessive testing of the alarm, while important for safety and ensures functionality, is managed within guidelines to avoid causing disturbances. Frequent fire drills are also vital for preparedness and should not be seen as a nuisance if conducted properly. Thus, the critical factor in determining a nuisance is directly related to issues with the alarm's installation or mechanical integrity.
