To answer your question, I don't know. Instead, here is a bizarre video made by what I can only assume is the lift-related equivalent of a TVF Rota Obsessive.
Bonkers new lift at work

The reason those lifts are better is because the lifts' destinations are pre-planned in advance. Assuming there is more than one lift, this means lifts can be allocated efficiently.
Also, it uses less energy for two lifts to stop at floors that are close by to each respective lift due to the speeds reached and thus braking power required.
Scenario 1:
Lift A going to floors 5, 35
Lift B going to floors 6, 36
Lifts A and B both use lots of energy because they both have to accelerate hard to get to each floor in a timely manner.
Scenario 2:
Lift A goes to floors 5, 6
Lift B goes to floors 35, 36
Each lift only has to accelerate 'hard' once, to get to the relevant floor grouping.
Also it means that you get a lift quicker due to said bunching, and especially it means that you get the most appropriate lift when you are on a higher floor and request to go down. (Traditionally you get the first lift that happens to be passing downwards, unless there is no lift in which case one is sent especially for you. The new system gives you a lift that is doing your floor grouping at the same time. This is bad for you since it actually takes longer to go down but it is great for the environment so you can feel good about yourself while waiting).
And of course it means there isn't a stupid scene involving the pressing of buttons which means the doors can close faster (waiting for a button to be pressed is a common bottleneck with lifts).
I have no idea why you are limited to calling three floors at a time though. The system is at its best when handling lots (like 30 or 40) differnet floor requests, as is the case in some insanely busy american office blocks, as that allows the 6 or whatever lifts to be put to good use andd provides a tangible benifit rather htan being an expensive time waster.
I suspect more likely your work has just been sold a bill of goods by some lift company and thus ended up with something more complicated than their needs.
(The main concern IMO is the fact that since the buttons inside the lift are never tested, how do you have any confidence the alarm button works?)

Just because other buttons in a lift doesn't mean the alarm button works. I would expect it to be tested during servicing or routine maintenance.cdd wrote: (The main concern IMO is the fact that since the buttons inside the lift are never tested, how do you have any confidence the alarm button works?)

I liked one line used in a video description: "at this rate the whole of england will just have dull generic lifts."
*gasp*
