Abstract
Abstract A method of operating an elevator system includes the steps of specifying and storing at least one profile describing at least one elevator operational characteristic, including an elevator security function specifying a landing or landings for which hall calls are not to be responded to and a landing or landings for which car calls are not to be responded to. The profile has a start time, an end time, and a day or days of the week specified therefor during which time the profile is to be activated. A next step repetitively determines a current time and a current day of the week and compares the current time and current day of the week to the specified start time, end time, and day or days of the week associated with the at least one stored profile. Responsive to an equality condition, the method includes a further step of transmitting information to a controller of at least one elevator car within a group of elevator cars. The transmitted information causes the at least one elevator car to begin operating in accordance with the specified profile, or to stop operating in accordance with the specified profile.
