Abstract

An exemplary method of controlling a plurality of elevator cars includes determining that there is a security violation condition involving at least one of the elevator cars at a landing. That elevator car is prevented from moving from the landing until the condition is resolved. The other elevator cars are controlled such that they do not provide elevator service to or from the landing until the condition is resolved.
