The Bell Corridor, situated outside the butler's pantry, held banks of bells, each linked mechanically by wires to the rooms occupied by the Family. They were used by members of the Family, and their guests, to summon servants to any room in the house. Each one is labelled, and a small pendulum attached. This ensures that, even if a servant arrives after the bell has stopped ringing, the swinging pendulum indicates which bell has been rung.

In 1921, this system was superseded by an electrically operated one. However, the Family did not like it, and were soon using the old mechanical system once more.
