Abstract
A control arrangement for an entrance system has one or more movable door members and an automatic door operator for causing movements of the one or more movable door members between closed and open positions. The door members comprise one or more swing doors. The control arrangement comprises a controller and a plurality of sensors. Each sensor is connected to the controller and is configured to monitor a respective zone at the entrance system for presence or activity of a person or object. Each sensor has an active mode and an inactive mode, wherein the sensor consumes no electric power in the inactive mode or substantially less electric power in the inactive mode than in the active mode. The controller is configured to determine a current operational state of the entrance system among a plurality of possible operational states, and selectively cause at least one of the sensors to be in its active mode or in its inactive mode depending on the determined current operational state of the entrance system.
