Which of the following is NOT a common feature of ACS software?

In the context of ACS (Access Control Systems) software, the primary function is focused on managing access to secure areas and monitoring user activity rather than replacing existing fire alarm systems. The key features of ACS software include user management, which allows administrators to set permissions and access levels for different users; integration with alarms, enabling the system to interact with alarm systems for increased security; and real-time reporting, which provides actionable insights based on access logs and events.

The inclusion of existing fire alarm systems falls outside the typical scope of ACS functionalities. Instead, fire alarms serve a distinct purpose in fire safety and prevention, rather than access management. Therefore, identifying replacement of a fire alarm system as a non-feature truly captures the essence of what ACS software is designed to accomplish.
