Figure 5-3 Shows two NACs on a Signature data circuit. Each
NAC is controlled by a SIGA-CC1S module, one for audible
appliances, and one for visible appliances.
As in Figure 5-1, this configuration allows the audible appliances
to be silenced independently of the visible appliances. This
operation is optional, and may or may not be required for your
project.
The SIGA-CC1S modules provide signal synchronization for
both NACs.
