A Straight Dope Classic from Cecil's storehouse of human knowledge
07-Nov-1986
Dear Cecil:
Please confirm or refute my suspicions. Does the "Close Door" button on an
elevator actually do anything, or is it provided merely as a tension-releaser for us
harried yuppies? I await an uplifting answer. --Leonard V., Silver Spring, Maryland
Cecil replies:
Spare me the pathetic puns, Lennie; this is serious business. The grim truth is that a
significant percentage of the close-door buttons in this world, for reasons that we will
discuss anon, don't do anything at all.
Naturally, this is not something the elevator companies wish to have widely known, lest
there be social unrest. When I talked to the folks at the Otis elevator company in
Farmington, Connecticut, they were all innocence.
Among other things, I was told that the close-door buttons at Otis HQ (which, the views of
the cynics notwithstanding, is not located in a one-story building) always work like a
charm.
This is comforting news, needless to say. I would suggest that any harried city dweller
who has never seen a close-door button that actually did something might want to make a
field trip out to Farmington to inspect the genuine article.
In the meantime, having consulted with various elevator repairmen, I would say that
apparent CDB nonfunctionality may be explained by one of the following:
(1) The button really does work, it's just set on time delay.
Suppose the elevator is set so that the doors close automatically after five seconds. The
close-door button can be set to close the doors after two or three seconds. The button may
be operating properly when you push it, but because there's still a delay, you don't
realize it.
(2) The button is broken. Since a broken close-door button will not render the elevator
inoperable and thus does not necessitate an emergency service call, it may remain
unrepaired for weeks.
(3) The button has been disconnected, usually because the building owner received too many
complaints from passengers who had somebody slam the doors on them.
(4) The button was never wired up in the first place. One repair type alleges that this
accounts for the majority of cases. In other words, the whole thing is a total scam.
Watergate, Iran-contra, and now this. And they wonder why we've lost faith.
OBSERVATIONS FROM THE FIELD
Dear Cecil:
Your source at the Otis Elevator Company seems not to have been entirely forthcoming, or
perhaps only Brand X elevators have "close door" buttons that function in yet a
fifth way.
At my grade and high school in New York (the building opened in 1966), the elevators
usually operated in automatic mode--you pushed the button for your floor, and eventually
the doors closed and the elevator took you where you wanted to go.
But for special occasions the elevator could be keyed into "operator" or manual
mode. The doors would stay open until you pressed and held the "close door"
button.
(If you released it before they were completely shut, they would just slowly open up
again, and you couldn't do a thing about it until they were finished. That could be real
embarrassing when you were, say, ferrying visiting parents to their teacher conferences.)
"Open door" always worked, but "close door" didn't seem to
have any other effect. --Peter D., Chicago
Dear Cecil:
Just a comment on your recent investigation of "close door" button operation. I
visited Otis Elevator HQ last spring and had to walk up to the second floor because the
elevator was out of order. The "close door" buttons may work there, but the rest
of the elevator is a little chancy. --S.G., Chicago
