Paging
The DBS allows extensions to be grouped into paging groups numbered 00-
07. When you issue a page (by dialing #00-#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.
External zone paging allows you to connect up to five speaker groups to the
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
01-04 correspond to groups 01-04. 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 external page group. These are used when paging
and UNA use the same paging amplifier system. (See notes for more
information.)
Guidelines
• The paging amplifier, zone relays, and speakers are not provided with the
DBS. They must be purchased separately.
• The maximum current for each zone paging terminal on the Connector
Panel (Z0-Z4) 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
30V DC, 1 amp (maximum).
• Connector 4 (CN4) on the Connector Panel is used to connect the paging
amplifier. The output impedance of CN4 is 600 Ohms; the loss/gain setting
is 0 dB.
External Page Zone Installation
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.
