What is a bump test in the context of gate safety?

• A. A test simulating an obstacle by gently applying pressure to the edge or sensor to confirm safety devices respond appropriately
• B. A test of the gate color scheme
• C. A routine calibration of timer
• D. A test of the gate's color reflectivity

Answer: (A)

A bump test is a quick safety check of the gate’s obstacle-detection system. It involves gently applying pressure to the gate’s edge or to the sensing area to simulate an obstacle. If the safety system is working, this simulated contact should be detected and the gate will stop or reverse promptly, proving that the protective devices are responsive and protecting against entrapment. This test focuses on how the sensors and safety edges react—not on appearance, timers, or color properties.
