What can reduce the occurrence of unwarranted alarms?

The option that reduces the occurrence of unwarranted alarms is the alarm verification features. These features are designed to assess whether an alarm signal is genuine or erroneous before taking further action, such as notifying emergency responders. By incorporating methods to verify alarm signals, such as delays or secondary checks, the system can help distinguish between legitimate threats and false alarms, ultimately minimizing unnecessary disruptions and ensuring that emergency services are dispatched only when truly needed.

By contrast, while fire drills and inspections can contribute positively to overall safety procedures and building preparedness, they do not directly address the technological aspect of alarm systems that lead to unwarranted triggers. Hiring additional staff may bolster response times or support operational functions but does not inherently resolve issues related to the reliability of the alarm systems themselves.
