When an elevator reaches its maximum height without a slowdown, the most immediate response is for the emergency brakes to engage. This is a crucial safety feature designed to prevent potential accidents. The emergency brakes are triggered to halt the elevator when it exceeds the permissible limit. This response ensures that the elevator does not potentially go beyond its designed stopping point, which could lead to severe mechanical failure or pose a risk to passenger safety.

In certain elevator systems, there are also mechanisms such as limit switches that detect when the elevator reaches its maximum travel height. Engaging the emergency brakes is a proactive measure to safeguard against exceeding those limits. Other responses, such as sending a warning signal, automatic shutoff, or continued upward movement, may not occur immediately in the same way as the brakes engaging, which is why the first option is the most appropriate answer in this scenario.
