One-family house with three panels
In a ABB-Welcome IP system in a private building the building network is disconnected from the
units network. This prevents unauthorized access to the private units network via the outdoor

Three IP Touch 7 devices are installed.
In this type of installation the master IP Touch 7 additionally meets the function of an IP
gateway.
