Standard call numbers
ATTENTION: Changing automatic allocated calling numbers
The standard calling numbers, that are automatically allocated to the housings (see page 25), must be
changed if more than 9 housings are connected! Otherwise, three- and four-digit numbers begin with
the same numerical sequence (e.g. “110” in housing no. 1 and “1101” in housing no. 11)!
