In gate safety features, what does the hold-open device do?

• A. It starts the motor
• B. It temporarily maintains the gate in an open position to allow pedestrian passage
• C. It signals an error
• D. It locks the gate closed

Answer: (B)

Hold-open devices temporarily keep the gate in the open position to allow pedestrians to pass. They override the normal closing cycle for a set period or until a manual release, so people can walk through without the gate trying to close immediately. After the hold time, the system resumes its usual safety sequence and can close when it’s safe. This feature is specifically about maintaining an open state for convenience and safety, not about starting the motor, signaling errors, or keeping the gate locked shut.
