The configuration of the Gira door communication system can be carried out via GPA prior to installation and thus shorten the time needed for configuration. The DCS data interface is used for connection of the analogue 2-wire bus to IP. Additionally, the configuration data of existing systems can be read out. The combination with other product groups is possible, e.g. door communication with logic module Gira L1 or Gira X1. Muting of individual home stations is made possible by the central control via IP. The occupancy simulation makes it possible, for example, for lights to be switched on in the house if the doorbell is rung while you are not home. This simulates movement in the house.
