Security door alarms are essential in an Access Control System (AACS) primarily because they are designed to signal unauthorized access attempts. This feature is crucial for maintaining the security of a facility by alerting personnel to potential breaches in security. When an unauthorized individual attempts to access a secure area, the alarm serves as an immediate warning system that can help in taking prompt action to address the potential threat.

By ensuring that any unauthorized entries are detected quickly, organizations can better protect sensitive areas and data, thereby mitigating risks associated with theft, vandalism, or other security incidents. The primary purpose of security door alarms aligns closely with the need for heightened security measures in environments that require stringent access controls.

The other options do not pertain to the fundamental role of security door alarms within an access control system. These alarms are not intended for entertainment, measuring attendance, or reducing energy consumption, thus emphasizing their vital function in safeguarding an organization's assets and personnel.
