The 4 wires from the communication bus of the alarm panel are
connected at the data BUS as described in the installation
instructions of the alarm panel. Additional modules are
connected in parallel at this BUS. The zone ranges are
differentiated by the addressing of the modules.
You must also set the type of zone wiring. The zone types from
the alarm centre and the expansion modules may be different.
NOTE:
When putting into operation, the alarm centre automatically learns
which zones are additionally assigned by the expansion module.
