emergency stop buttongreenspun.com : LUSENET : Elevator Problem Discussion : One Thread
Hi my name is phil and i dont know anything about elevators i must admit. Anyway, i work for a hotle and it gets alot of french tourist (they are old), and seem to always mistakenly push the emergency stop button. once they push that red button the elevator alarm goes on and it stops and u must pull the button back out for it to work again. is there a way for me to make the elevator come to the lobby and open the door form outside?

Phil, No. When the emergency stop switch is activated, there is no way for you to overide it. It is designed for emergency stops only. Check with your elevator serviceman for ideas. Hope this helped, Jim

Hi THere The solution is to install a stop button that is pull to stop and push to run or check your code and install a key operated stop switch. If you stil are having trouble please send a first class ticket and I will install one for you, If you are in Paris thats even better because I want to check out those hydralic elevators in the eifel tower anyway. Do you know the history behind those elevators in the eifel tower, very interesting. Pierre

One solution we have for this type of problem is to instal a clear plastic cover over the stop button, which is hinged so that it can be lifted if the stop button ever genuinely needs to be pressed. We have a lot of trouble with car panels that are mounted at hip level, with purses, briefcases, umbrellas and even coffee cups activating stop buttons accidentally. Placing a cover over these has done wonders...however, it NEVER stops teenagers and small children from being curious....

A stop button should only be fitted in the car if:- 1/ There is no car doors fitted to the lift 2/ The car doors are of a open latice type 3/ Local code require's it 4/ Or some obsolete control type require's
If the car has fully protected with sealed doors manual or automatic there is no need for a stop button in the car. If you are using it to hold the doors open, fit a door hold bypass key switch.

only until recently the Australian lift code stipulated EVERY automatic control lift Had to have a stop button....the latest changes now dont need one but some companies are fitting key operated stop switches.

Is Phil from OZ Dayle? If not he should find out what his code is. Q. When's a emergency stop not an emergency stop? A. When it's a KEY switch!!!!!! Whats the point have it ripped out.

Even sealed-door elevators should have an emergency stop. It should be easy to hit (in a panic, you don't want to "pull the button to stop")
In a recent event, an elevator was returning to its home floor after a fire alarm was triggered. However, that ground level floor was flooded due to local flooding, and the occupants had no way to stop the elevator. An E-Stop *may* mave allowed them escape.

What IS the thinking behind the emergency stop switch... If Otis's web page is correct... http://www.otis.com/modernizationdetail/1,1426,CLI1_MID9071_RES1,00.h tml Keyed stop switches are REQUIRED by current elevator code (ASME). What about that doctor that got his head crushed by an elevator door... was it in Texas? within the last year... I always thought if there was a quick thinking bystander a quick jab of a stop button might have saved his life.
What good is a keyed switch? Is the elevator service man going to put his key in there in case he needs to use it during maintenance? I am sure not going to fumble for my keys while someones head or arm is traped in the doorway of a moving elevator !
I know the concern is that someone will stop the car, trap a victim for robbery or whatever, but usually that is surviveable... and if the alarm bell and alarm signal goes out to a central station the robber has to be brave and dumb to try it.

Yes I agree....BUT as I stated B4 the latest codes in Australia state there is no reason for an emergency stop button.......in a mod job usually it is replaced with a key switch..but in most new installations there is NOTHING....i.e Gen2.......actually in a new KONE job ive seen they had a keyswitch......is Europe the same...most of our codes here have been downgraded to everyone elses standards....the Australia code used to be the worlds toughest....and somethings still are (although a lot were so damn stupid)....deregulation dilutes a lot of things.

EN81 has outlawed stop switches AKA "rape buttons" for as as long as I remember i.e, the 70's, OK, actually before that...
Honestly, I can't think of a reason to provide one, except of course Our "Local" code requires it, and of course that is a good reason ....
Why don't we still demand the the guy with the red flag walking in from of cars?
