Identification and numbering order for expanders and keypads differ depending on automatic or manual addressing of the expanders. For information on manual and automatic configuration, see X-BUS.

For a system with manual addressing, expanders and keypads have a separate numbering sequence and are defined by the engineer manually. That is, expanders are numbered 01, 02, 03, etc. as desired. Using same numbers, keypads may be numbered as desired.

In the manual configuration, the system automatically allocates zones to each expander. For this reason, devices with no zones, such as 8 output expanders should be addressed last.

For a system with automatic addressing, expanders and keypads belong to the same numbering group and are assigned by the controller. That is, expanders and keypads are together numbered 01, 02, 03, in the order that they are detected relative to the location of the controller.
