Caution
For the time being, Vandal resistant panels are available only for single-
button sets with one extending module at most.
Installing the info panel name plate, order No. 9135311E, into any of the
extending modules will not change the numbering system (the buttons on
the info panel sides will remain functional).
Connecting the info panel module, order No. 9135310E, will result in
omission of eight numbers.
