What effect does burying the arresting chain have on the performance of the E-5 barrier?

• A. It causes misalignment
• B. No effect
• C. It increases reset time
• D. It improves stopping distance

Answer: (B)

Arresting chain acts as a fixed limiter for the barrier’s travel. Whether it’s buried or visible doesn’t change the barrier’s drive, braking, or control timing that determine stopping distance and reset time. As long as the chain remains properly attached to its anchor and doesn’t interfere with moving parts, burying it simply hides it from view and does not alter how the barrier operates. So there is no change in performance. Other issues would come from wear or misalignment of the barrier components, not from the burial depth of the chain.
