What does the supervisor level allow in BAS access control?

• A. Assigning of access levels and codes to other individuals
• B. Viewing system status
• C. Editing firmware
• D. Scheduling maintenance

Answer: (B)

Role-based access control in a BAS assigns privileges by role, and the supervisor level is designed for oversight. The main capability at this level is viewing system status, which means you can monitor real-time conditions, equipment states, active alarms, and historical trends to keep an eye on how the system is performing. This keeps operations safe and stable by letting someone supervise without making changes that could affect the system.

Why this is the best fit: supervisors need situational awareness to detect issues and verify that everything is running as intended, but they aren’t authorized to modify configurations or credentials. Actions like assigning access levels and codes would enable broader access to the system, editing firmware would change device software, and scheduling maintenance alters the workflow and timing of upkeep—functions that require higher privileges or different roles.
