Alarm systems play a crucial role in security by detecting unauthorized access and emergencies, such as fires or intrusions, and then alerting the appropriate personnel or law enforcement. This immediate response capability is essential for protecting property and individuals. By sensing changes in the environment, such as when a door is opened without authorization or when smoke is detected, the alarm system acts as an early warning system, potentially preventing further escalation of threats.

This ability to notify key responders ensures timely intervention, which is vital for minimizing damage or injury. Other functions outlined in the incorrect options, such as initiating lockdowns randomly or notifying management of safety audits, do not align with the primary purpose of alarm systems. Similarly, simply informing employees of schedule changes is not a function associated with security alarm systems.
