I know that this works if the lift is under fire control. Except that you have to continue to hold the floor button until the floor then hold the open door button.
I don't recall seeing the close doors button in a lift for years.
every lift I've ever used had a close doors button.
I can see people getting in trouble at the EduGeek Conference!
my workplace has only got 2 floors so it'll work here :)
tried and tested at my friends block of flats this morning, works a charm
Had anyone else called for the lift at any other floors though?
Did they run out of 4's when they were printing off the lift buttons?
could be a asian building where the number 4 is considered unlucky
