COMMON AUDIBLE AND AUXILIARY
RINGING INTERFACE
Relay closure dry-contact points are available for controlling
e x t e r n a l a u d i b l e e q u i p m e n t . T h e s e c o n t a c t c l o s u r e s t r a c k
the pattern of the ringing . The contacts are closed during
the ringing period and are open during the silent period. A
typical common audible connection is illustrated on
Figure
3-9
below.
Do not exceed a 1 amp at 24 volts (0.5 amp at 48
volts) load on these control terminals. If the
load requirements exceed this limit, connect the
load through an external slave relay. DO NOT
CONNECT THESE CONTROL TERMINALS
DIRECTLY TO THE 117VAC LINE.
Outside Lines
l
Common audible terminals provide a dry-contact closure
whenever any of the outside lines that are connected to
t h e c o m m o n e q u i p m e n t .
Selected Ports
The station 17 audible terminals provide a dry-contact relay
closure whenever ringing is sent to a programmable
destination. Class of service programming is used to
either the paging port or station port 17 as the
ringing destination. Refer to page 4-13 for details.
When programmed for station port 17 ringing,
an external
device is often used to provide loud ringing similar to the
common audible arrangement shown in Figure
When programmed forpaging port ringing,
an external
paging amplifier is employed to amplify and broadcast the
ringing tones sent to the paging port. The relay closures that
appear at the ringing terminals can be employed to energize
the external paging amplifier during the periods when the
ringing tones are being sent.
NOTE: Refer to the following paragraph
Interface for a discussion of external paging
connections and information for using the
paging port ringing terminals in an alternate paging
enable function.
