For
connections, refer to Figure 6.03.
An AC signaling device operated by
ringing voltage must be con-
nected to an SLMA circuit used for UNA. Each UNA circuit will drive up
to four equivalent ringer loads. For installations requiring
or a dry
contact closure for UNA. appropriate external equipment
must
be used.
The system will support up to four UNA signaling zones (i.e.;
one
SLMA circuit is assigned per zone.
