Abstract

A method of operating an elevator system includes presenting a credential at a security panel disposed at an elevator system landing of a public area of a building. If the presented credential is correct a contact between the security panel and an elevator control system is opened. Opening of the contact allows for placement of a call via the elevator control system for an elevator car to the landing. An elevator system includes one or more elevator cars located in one or more hoistways. An elevator control system controls movement of the elevator cars. A security panel is operably connected to the elevator control system and located at an elevator system landing. Presenting a correct credential at the security panel opens a contact between the security panel and the elevator control system thus initiating a call of an elevator car of the one or more elevator cars to the landing.
