Why is there an up and down button on elevators?

Rule #1: The two buttons available to call an elevator have an up arrow and a down arrow. These are meant to indicate whether you want to go up or down, not whether the elevator must come up or down. For example, if you’re on Floor 3 and you want to go to Floor 7, you need to press the Up arrow button.

How do elevators work buttons?
The buttons in the elevator car and the buttons on each floor are all wired to the computer. When you press one of these buttons, the computer logs this request. The computer varies the motor speed so that the car slows down gradually as it reaches each floor. This keeps the ride smooth for the passengers.
Button lifts work via an aerial steel loop that rotates on wheels and is powered by an engine. Attached are equally spaced poles hanging down and on the bottom of each pole is a button shaped plastic seat that is placed between the skier’s legs or under the snowboarder’s front leg and pulls them uphill.
What do the up and down buttons on an elevator do?
When multiple elevators are in use, the up and down (call) buttons serve to tell the system whether or not to stop an elevator at that floor. For instance, you are on the 5th floor and you want to go down.
How many call buttons do you need for an elevator?
In a building with two floors, you only need one call button. The system understands that you want to go to the other floor. If there are three floors, then the person on the middle floor might want to go up and might want to go down. If the elevator is already going to the wrong floor it will take three times as long to get to their destination.
How do you cancel a floor selection on an elevator?
You can cancel a floor selection on several types of elevators including OTIS, Mitsubishi Electric, and FUJITEC. Depending on the elevator model, you can try double-pressing the floor button (Mitsubishi Electric), quickly pressing the button five times (FUJITEC) or double-pressing the floor button while holding the “Open Door” button.
How do I put my Elevator into independent service mode?
Many older elevators can be put into “independent service” mode by pressing and holding both the Door Close and your desired floor buttons at the same time for 5 seconds. If successful, your elevator should go straight to your floor and bypass all other floors. I’ve tested it on multiple systems including older OTIS, DOVER, and DESERT models.
