The activation of a fire alarm is crucial for which of the following security measures?

The activation of a fire alarm plays a vital role in opening a delayed egress lock as it is designed to prioritize safety in emergency situations. When a fire alarm is triggered, the electronic access control system recognizes the emergency condition and may override the normal locking mechanism of delayed egress locks, allowing for immediate exit from the premises. This ensures that individuals can evacuate quickly and safely without being hindered by security measures that are typically intended to restrict access.

Delayed egress locks are set to prevent unauthorized exit but must have provisions that allow for a rapid evacuation when a fire alarm is activated. This aligns with life safety codes and regulations, emphasizing the importance of providing a clear and unobstructed path to safety during emergencies.

In this context, the other options do not relate directly to the function and purpose of fire alarm activation. For instance, disarming the alarm system contradicts the intent of responding to an emergency, while testing the system and monitoring entry logs focus more on routine security management rather than immediate safety response in the event of a fire.
