Each hutch is equipped with a Hutch Search Message which sounds while the hutch is being searched. The message starts as soon as you initiate a search of the hutch (by pressing the green button on the first search box).

The message consists of a red flashing light as seen at the right, as well as a computerized voice that instructs anyone in the hutch to leave. For example, if you are searching hutch C, the voice will repeat: "Searching Section C, Exit Immediately."
