Definitions

number of elevator groups

The number of groups of elevators in a structure, in which each elevator in the group shares the same control system.

The number of elevator groups in a structure or module indicates how many different elevator control systems are installed in that object, with each system controlling a group of one or more elevators.

Groups of elevators are divided according to control systems, not physical proximity. Typically elevators serving different floor zones (e.g. low-rise/high-rise) within a building belong to separate groups. Elevators spaced far apart in a building are also likely to form separate groups. Service or freight elevators are usually single (constituting a separate group), but may also fall under group control.
