Stand-alone automatic lighting control system: one disadvantage.

Stand-alone automatic lighting control system: one disadvantage.

• A. Low installation cost.
• B. Each light has to be configured separately.
• C. Faults can be identified by central system.
• D. Supports fault reporting.

Answer: (B)

Stand-alone automatic lighting control systems operate each light independently with its own control logic, sensors, or timers, and there is no central controller coordinating all fixtures. The main drawback is that every light has to be configured separately, since there’s no shared programming to apply across multiple luminaires. This makes setup slower and more labor-intensive for larger installations, and it can lead to inconsistencies unless each light is tuned individually. The other points describe benefits or features of centralized systems, which stand-alone setups don’t provide.
