The DBS allows extensions to be grouped into paging groups numbered OO-
07. When you issue a page (by dialing #IO-#07), you specify a paging group,
so that your announcement is heard over the key telephones and Digital
Single Line Telephones that are members of that group. Paging groups often
include people whose work is related.
DBS. Each speaker group is assigned to one of five paging zones (00-04).
Zone 00 corresponds to group 00. When you page group 00, your page is
heard over the All-Page Speaker(s) as well as all other external zones. Zones
0 l-04 correspond to groups 0 l-04. For example, when you page group 02, the
page is heard on the external speaker(s) assigned to zone 02. Paging groups
05-07 have no external paging zones.
If zone paging is not required, general paging relay terminals C (common), B
(break) and M (make) are also provided. The relay terminals activate any
time there is a page to an ex.&mal page group. These are used when paging
and UNA use the same paging amplifier system. (See notes for more
information.)
The paging amplifier, zone relays, and speakers are not provided with the
l
DBS. They must be purchased separately.
The maximum current for each zone paging terminal on the Connector
l
Panel (20-24) is 50 mA; the resistance of the relay used for each zone
paging terminal must be 2600 to 2800 Ohms.
The contact rating for the UNA/General Paging "C" and "M" terminals is
l
30V DC, 1 amp (maximum).
Connector 4 (CN4) on the Connector Panel is used to connect the paging
l
amplifier. The output impedance of CN4 is 600 Ohms; the loss/gain setting
is 0 dB.
1. Connect the paging amplifier to CN4 on the DBS Connector Panel. (See
Figure 5-7 on page 5- 15.)
2. Connect the paging speakers to the amplifier and relays.
