Door Open Time : LUSENET : Elevator Problem Discussion : One Thread

Hi, I was wondering if anybody knows how long it is required for elevator doors to remain open before closing again (if door close or floor has not been pressed). I was in an elevator today, pressed level 2 and no sooner than the doors had opened, they closed again and it went back to the home floor. I came back up to 2 and got out quickly, and when I came back to go down the lift doors hadn't even finished opening when they closed again before I could get to it from where I was waiting (no warning signals when the lift is arriving).

Anyway, enough of my ranting. I would appreciate it if someone could give me an indication of the average requirement.

door open time

the doors should stay open for 5 seconds before closing.Three seconds is also used in some busier buildings.

There a lot of aspects to this subject-The "correct" amount of stand open time depends on the application and is a matter of opinion. There are standards that set minimum times for the benefit of handicapped persons -The minimum delay for a car call is 3 seconds. For a hall call, the minimum is 5 seconds for hall calls, with the time starting when notification is given to the passenger that the car is answering a call. This would be when the hall lantern or car lantern becomes visible to the prospective passenger (one or the other, i.e., hall lanterns or a car riding lantern is mandatory). Many systems have means of cancelling stand open times once passenger transfer begins, or "instant door close" feature, where pushing a car call button cancels stand open time. These features cannot overide the handicapped requirements where same are enforced.

Door times are also determined by the installation specification, sometimes the lift companies have no say in the matter as this is determined by consultants during the tender process. I maintain a building with a bank of four lifts where two of them have a longer door time at the lobby to allow for disabled access, people always complain about it but I cannot shorten it because that's what was specified.

A lot of what the guys are saying is true, but it does depend on things like, local code, door size, speed of operators and user. However it sounds like you need to get it checked out. As car doors hitting people has a high claim input
