Creating a plan for devices (Fig. 8)
Each free@home device has a clear, eight-digit serial
number. It is affixed permanently to each device as well
as on a removable identification label.
It serves as an aid for identifying the devices during com-
missioning.
To facilitate the input a three-digit character code, which is
generated from the specific serial number, is additionally
available. Although it does not clearly identify the device,
its accuracy, however, is sufficient to make it unique in the
system.
To be able to identify the devices and channels more
clearly during commissioning, it is recommended to docu-
ment the three-digit character code of the devices, their
function and location already during their installation.
» To do this, pull off the removable labels from the de-
vices and document the associated functions on the
enclosed master (Plan of devices; see Fig. 48 ).
