EXTERNAL PAGING

The KSU provides a paging output to be used with customer-provided paging equipment. The MISC1
card provides an additional external page interface. Both interfaces are accessed via Tail 1.
Connect a paging amplifier to the paging output on the SDF via an AUSTEL approved music on hold
LIU.
The page output should be terminated with 600Ω. The paging output should be connected via a 600Ω
matching transformer if the paging amplifier input impedance is not 600Ω.
WARNING. Do not attempt to connect 240V AC power to these

COMMON BELL

A customer provided common bell or loud sounding alarm can be controlled using the dry contact pair
in the KSU. The connection should be made via an AUSTEL approved LIU.
The Common Bell should be connected in series with a suitable (customer provided) power source.
The Common Bell, with power source, should be connected between the 'Common' pin on the SDF
and the 'Normally Open' contact.
The system can be programmed, using MMC 204, for either Interrupted or Continuous operation of
the contacts. The interrupted selection follows the external call ring cadence of one second ON and
three seconds OFF.
After connection, the Common Bell must be assigned to a station group using MMC 601.
The basic steps for Common Bell operation are -
•
Wire the loud sounding device to the common bell control contact pair
•
Program the contacts for continuous or interrupted operation
•
Program the hunt group to include the common bell
•
Assign the trunk to ring the hunt group containing the common bell.
