A. MICROPROCESSOR BASED CONTROLLER: New state-of-the-art microprocessor-based programmable logic solid state controls will be provided with the following features: Fire Service per national and local code requirements. Two-way leveling. All ADA compliant features. Inspection operation. B. 3 CAR GROUP FUNCTIONALITY: Control of the elevators will be automatic in operation by means of push buttons in the car numbered to correspond to floors served, for registered car stops by "up-down" push buttons at each immediate landing and "call" push buttons at terminal landings. The momentary pressing of one or more buttons will dispatch the car to the designated landings in the order in which the landings are reached by the car, irrespective of the sequence in which the buttons are pressed. Each landing call will be cancelled when answered. When the car is traveling in the up direction, it will stop at all floors for which car buttons or "up" hall buttons have been pressed; it will not stop at floors when "down" buttons only have been pressed, unless the stop for that floor has been registered by a car button, or unless the down call is at the highest floor for which any buttons have been pressed. Likewise, the pressing of an "up" button when the car is traveling in the down direction will not stop the car unless the stop for that floor has been registered by a car button, or unless the up call is the lowest for which any button has been pressed...
