designated level: the main floor or other floor level that best serves the needs of emergency personnel for firefighting or rescue purposes identified by the building code or fire authority.
dispatching device, elevator automatic: a device, the principal function of which is to either:
(a) operate a signal in the car to indicate when the car should leave a designated landing, or
(b) actuate its starting mechanism when the car is at a designated landing
displacement switch: a device actuated by the displacement of the counterweight, at any point in the hoistway, to provide a signal that the counterweight has moved from its normal lane of travel or has left its guide rails.
door: the movable portion(s) of an entrance that closes the openings, It consists of one or more solid face panels which are permitted to be equipped with a vision panel.
door,folding: a hinged door consisting of two or more panels that fold and move horizontally.
door, horizontally sliding: a door that moves horizontally.
center-opening: a horizontally sliding door consisting of two panels, so arranged to open away from each other.
center-opening, multiple—speed: a horizontally sliding door consisting of more than two panels, so arranged that the panels or groups of panels open away from each other.
multiple-speed: a horizontally sliding door with two or more panels, so arranged to open away from one side.
single-speed: a one-panel horizontally sliding door.
door or gate, manually operated: a door or gate that is opened and closed by hand.
door or gate, power-operated: a door or gate that is opened and closed by a door or gate power-operator.
door or gate, self-closing: a manually opened door or gate that closes when released.
door, szvinging: a door that pivots around a vertical axis.

door or gate closer: a device that closes a door or gate by means of a spring or gravity.
door or gate electric contact: an electrical device, the function of which is to prevent operation of the driving machine by the normal operating device unless the door or gate is in the closed position.
door or gate power operator: a device or assembly of devices that opens a hoistway door(s) and/or a car door or car gate by power other than hand, gravity, springs, or the movement of the car; and that closes them by power other than hand, gravity, or the movement of the car.

dumbwaiter, hand: a dumbwaiter utilizing manual energy to move the car.
dumbwaiter, power: a dumbwaiter utilizing energy other than gravitational or manual to move the car.
dumbwaiter, electric: a power dumbwaiter where the energy is applied by means of an electric driving machine.
dumbwaiter, hydraulic: a power dumbwaiter where the energy is applied, by means of a liquid under pressure, in a cylinder equipped with a plunger or piston.
clu mbwa iter, direct—phi uger hydra ii tic: a hydraulic dumbwaiter having a plunger or cylinder directly attached to the car frame or platform.
dumbwaiter, eIe’ctrohL/draulic: a direct-plunger dumbwaiter where liquid is pumped under pressure directly into the cylinder by a pump driven by an electric motor.
dumbwaiter, maintained—press nrc hydra ii hic: a direct— plunger dumbwaiter where liquid under pressure is available at all times for transfer into the cylinder.
