What happens in an EAC system when power is lost and it is designed to be fail-safe?

• A. The system automatically shuts down
• B. The system defaults to a secure state
• C. The system continues normal operations
• D. The system releases all locks

Answer: (B)

In a fail-safe design within an Electronic Access Control (EAC) system, the primary intention is to prioritize safety and security during a power loss. When power is lost, the system defaults to a secure state to ensure that unauthorized access is prevented. This is crucial in environments that require high security, as it mitigates the risk of breaches during such events. By defaulting to a secure state, the system ensures that all access points remain locked, thereby preventing individuals from entering secured areas without the proper credentials. This design choice reflects the principle that, in situations where control over access cannot be maintained, the safest course of action is to restrict access entirely rather than allow entry without verification. The other options do not accurately describe the mechanism of a fail-safe EAC system. Automatic shutdowns could lead to potential vulnerabilities, while continuing normal operations or releasing all locks would compromise security. Therefore, maintaining a secure state in the event of power loss aligns with the fundamental goal of EAC systems, which is to safeguard personnel and assets.
