Unauthorized access is a primary trigger for security alarms because these systems are specifically designed to protect premises from intrusions. When someone tries to enter a secured area without proper credentials or permission, the alarm system detects this breach. This could occur when a person attempts to force entry, uses stolen access codes, or bypasses security measures entirely.

The alarm's activation serves to alert security personnel or law enforcement to respond quickly to the potential threat. In contrast, routine maintenance generally does not activate alarms as it is expected and planned work conducted by authorized personnel. Delayed responses may indicate a problem with the system rather than trigger an alarm. Lastly, "none of the above" does not apply here since unauthorized access is a valid and common reason for an alarm to be set off. Understanding the different triggers for alarms helps security personnel effectively respond to security breaches and ensure the safety of the premises they are monitoring.
