Single push buttons shall be provided at each terminal landing and UP and DOWN buttons at each intermediate landing. Both car and corridor operating station shall be of the flush-mounted type.

2. The operation shall be such that momentary pressure of one of more car

or landing buttons, other than those for the landing at which the car is stopped, shall start the car, provided the interlock circuits are established, and cause the car to stop at the first landing for which a car or landing button is pressed corresponding tot he direction in which the car is traveling. The car shall successively stop at all landings for which calls are registered and these stops shall be made in the order in which the landings are reached irrespective of the sequence in which the buttons were pressed, provided the button for a given landing is pressed sufficiently in advance of the arrival of the car at that landing to permit the stop to be made. If no car buttons are pressed and the car starts UP in response to several DOWN calls, the car shall proceed first to the highest DOWN call then reverse to answer the other collected DOWN calls. UP calls shall be answered similarly when the car starts DOWN in response to such collected calls. If the car stops for a landing call and a car button is pressed within a predetermined interval after the stop, for a landing corresponding to the direction the car was traveling, the car shall proceed in the same direction regardless of other landing calls registered.

3. If DOWN landing buttons are pressed while the car is traveling UP, the

car shall not stop at these landings, but these calls shall remain registered. After the highest car and landing calls have been answered and the door interlock circuit is established the car shall reverse automatically and respond to DOWN car and landing calls. When traveling DOWN the car shall not respond to UP landing calls, but these calls shall remain registered and be answered on the next UP trip. A timed relay shall hold the car for a few seconds at the landings at which stops are made to enable passengers to enter or leave the car. Pressure of a car button for another landing before this time elapses shall cancel the time and if power-operated doors are provided shall cause the doors to close and the car to start immediately. Operating the emergency stop switch shall interrupt the power supply and stop the car. Operating the emergency stop switch shall not cancel registered calls and after the switch is closed, the car shall continue to answer registered calls. Turning the independent service switch to the ON position shall cancel the registered landing calls and the car shall respond only to the car buttons.


ELEVATORS 140001-17

interval. Closing may be initiated instantaneously by registration of a car call.

3. The doors will remain open as long as the electronic detector senses the

presence of a passenger or object in the door opening. 4. If a passenger or object is detected during normal closing operation, the

doors will immediately stop and re-open. Closing will be initiated one-half second after the passenger or object has moved from the opening.

5. The circuitry will be arranged to inactivate the electronic detectors should

they fail to operate. However, the electromechanical reversal edge will not be deactivated by failure of the electronic detector or its removal from the circuitry by means of a manual switch.
