What is a typical sequence of operations when a gate is activated by a remote control?

• A. Gate opens first, then remote activation, with no safety checks.
• B. Remote activation, safety device check, gate opens to fully open, hold-open time, gate closes with safety checks, stops at closed.
• C. Remote activation, gate closes immediately.
• D. Hold-open time is ignored.

Answer: (B)

When a gate is activated by a remote, the operation follows a safety-first sequence: remote activation triggers the system, then safety device checks are performed before any movement; the gate opens to its fully open position, then a hold-open time allows passage; after that, the gate closes with safety checks in place and stops in the closed position. This order ensures people and objects are protected, clearance is verified before moving, and the gate doesn’t slam shut while someone is passing. If an obstacle is detected, the safety system would intervene, stopping or reversing as needed, which is why advancing straight to movement or skipping safety checks isn’t acceptable, and closing immediately or ignoring hold-open time would undermine safety and usability.
