Which component ensures a gate can be controlled by a building management system or access control system?

• A. Power supply module
• B. Gate controller interface
• C. Manual switch
• D. Weatherproof enclosure

Answer: (B)

This question focuses on how a gate connects to external control systems to enable remote operation. The component that makes this possible is the gate controller interface. It serves as the bridge between the building management system or access control system and the gate operator, taking open/close commands and status signals from the BMS/ACS and translating them into the control signals the gate motor can execute. It also sends back status and fault information, enabling monitoring and coordinated control. Additionally, it often supports common communication protocols, ensuring compatibility with different systems. Power supply, manual switch, and weatherproof enclosure provide power, manual operation, or protection, but they do not enable remote control or integration with other systems—the gate controller interface is what enables that integration.
