Installation
1. Connect the external ringer to the “C” and “M” terminals on the
Connector Panel. (See Figure 5-9 on page 5-18.)
Note:
When the Ring Patterns for UNA Terminals (M, C, & B)
programming command (FF1 2# 4# 1# (0 or 1)# is set to 0, connecting the
ringer to the “C” and “M” terminals provides a “1 second on/3 seconds
off” ringing pattern and connecting to “C” and “B” terminals provides a
“1 second off/3 seconds on” ringing pattern.
2. Connect the external ringer to its DC power source.

Notes:
• Most often, Unlivery Night Answer notification is provided by an external
ringer device. Universal Night Answer (UNA) can alternatively be set to
ring over the paging system. See “Paging” on page 5-14 for more
information.
• If UNA operates over a external ringer device, it is not recommend that
external paging also be used. Since contacts C, B and M activate for both
UNA calls and external pages, the external ringer device would turn ON
for all pages.
