The effectiveness of entry control systems is typically measured by:
Throughput (speed of entry)
False Acceptance Rate (FAR) - unauthorized access
False Rejection Rate (FRR) - denial of access to authorized users
These metrics provide insight into both the security and user experience of the access control system.
A (Cost) is relevant to budgeting, not effectiveness.
B (Activation delays) may affect throughput but isn't a primary measure.
D (System obsolescence) relates to lifecycle, not effectiveness.

When a bomb threat targets a specific floor, safety protocols typically mandate evacuation of the identified floor and the floors immediately above and below. This accounts for the potential blast radius and structural impact, ensuring personnel safety in adjacent vulnerable areas.
A is too vague.
C and D (all floors above or below) may be excessive unless threat specifics demand it.

Fire alarm and signaling systems are typically categorized as:
Auxiliary systems
Remote station systems
Central station systems
"Global" is not a recognized category of fire signaling systems. It may refer to a scale of operations or communication networks, but it is not part of the standard classification in fire alarm systems.

Private security functions are generally client-centered-focused on protecting the assets, people, and interests of a private entity or organization. In contrast, public law enforcement is tasked with serving the community at large, maintaining public order, and enforcing laws for societal benefit.
This fundamental difference in mission and orientation underpins many of the operational and strategic differences between the two sectors.
