Up to 12 unique addresses are possible within a single system. Only contact information from units with the same address is
exchanged. Multiple units can exist with the same unit address in which case the contacts behave in an OR function so that an input
from any unit with the same address will trigger its corresponding output on as many units that have a matching address.
Please refer to Figure 12 for example system topologies.
