Why is redundancy important in BAS hardware design?

• A. It reduces initial installation cost
• B. It ensures continuous operation during component failures, maintaining comfort and safety
• C. It simplifies configuration
• D. It increases the maximum sensors supported

Answer: (B)

Redundancy in BAS hardware design means having backup components or alternate paths so the system can keep operating if something fails. This matters because BAS controls climate, comfort, and safety-critical functions; a failed sensor, controller, or power supply could cause uncomfortable conditions or unsafe situations if there’s no backup. With redundancy, a spare controller, duplicate power, or an alternate communication path can take over automatically, so essential cooling, heating, ventilation, and safety-related tasks stay online. This resilience is the primary reason redundancy is used. The other options describe cost savings, simplified setup, or expanded capacity, which aren’t the focus of redundancy.
