Method for indicating elevator service status and elevator call device

An elevator call-out device, comprising:

• a call-out button for inputting a request to cause an elevator car to move upward or downward relative to a landing station where the elevator call-out device is located;
• visual signs associated with directions of movement of the elevator car indicated by the call-out button;
• a control unit configured to:
• upon receiving the request input via the call-out button to cause the elevator car to move upward or downward relative to the landing station where the elevator call-out device is located, switch one of the visual signs, which corresponds to the requested direction of movement, from an off state to a normally lit state;
• in response to the elevator car stopping at the landing station where the elevator call-out device is located, switch the one of the visual signs, which corresponds to a direction of movement of the elevator car in which the elevator car will move after stopping, from the normally lit state to a flashing state;
• and
• in response to a door of the elevator car closing or a door of the landing station where the elevator call-out device is closed closing, switch the one of the visual signs, which corresponds to the direction of movement of the elevator car in which the elevator car will move after stopping, from the flashing state to the off state;
• wherein the flashing state is a state in which the one of the visual signs provides a dynamic display effect by varying the luminous intensity of the one of the visual signs within a set range or by varying a color of the one of the visual signs;
• and
• wherein a frequency of luminous intensity or color change of the one of the visual signs is set within the normal range of respiratory frequency.
