Call relays in front of A lift’s floor selector. Each one of these linked to the call buttons in the lift car itself and in the landings as well. There is, for example, 3U (call from 3rd floor landing, going up), 3D (as 3U but going down) and 3C for a call to stop at the 3rd floor from the lift car itself. 24 Sep 2011
