In accordance with an elevator system for controlling a response to a call of the present invention, each of sub-controllers includes a unit of storing the information regarding service ability to a hall call, and a unit of determining service ability based on the information stored in the unit when the call is generated from the hall, regardless of a call response signal from a main controller. As a result, the determination and display of service ability to the hall call can be rapidly exactly performed. In addition, the main controller includes a unit of checking and determining abnormality of the sub-controllers, and a unit of storing an identifier of the abnormal sub-controller. Since the data is not transmitted to the abnormal sub-controller, a data transmission amount may be decreased. Also, during the repair or replacement work of the abnormal sub-controller, an identifier thereof can be rapidly confirmed. Moreover, the sub-controller includes a unit of checking and determining abnormality of the main controller. When the main controller is abnormally operated, a response lamp is turned off. As a result, the passengers are informed of that the elevator car is not able to provide the service, and thus do not unnecessarily wait for the elevator car at the hall.
