PART 7. CONNECTING OPTIONAL EQUIPMENT

7.1 MUSIC ON HOLD/BACK GROUND MUSIC

Connect each customer-provided music source to the music input on the KSU connecting block (see
Figure 7–1). The music input on the Trunk A card has internal automatic gain compensation
f e a t u r e s .
Each C.O. line (trunk) can be programmed to receive a music source, system generated TONE or
NO MUSIC when it is put on hold. See MMC 408. Each keyset can receive a music source or NO
MUSIC for background music. See programming manual for instructions (see MMC 308).
7.2 EXTERNAL PA G I N G
The KSU provides a voice pair to be used with customer-provided paging equipment.
Connect the customer provided paging equipment to the page output pins of the KSU connecting
block (see Figure 7–2). The page voice pair is 600 ohm impedance. When the amplifier page input
is not 600 ohm, an impedance matching transformer must be used.
If installed, the MISC card provides four zone control relays (see Figure 7–3). These paging contact
pairs are for control of low voltage circuits or amplifier output. The contacts are rated at 24 VDC-1
a m p .
WA R N I N G : Do not attempt to connect commercial AC power to these contacts.

7.3 COMMON BELL

A customer-provided loud ringing device can be controlled using the dry contact pair on the KSU.
See Figure 7–4.
Programming allows for INTERRUPTED or CONTINUOUS operation of the contacts using MMC
204. The interrupted selection follows the C.O. ring cadence - one second ON/two seconds OFF.
After connecting a common bell, you must assign it to a group in MMC 601 as a ring destination by
using the code for Common Bell.
The basic steps for common bell operation are the following:
a. Wire the loud ringing device to the common bell control contact pair.
b. Program the contacts for continuous or steady operation.
c. Program the hunt group to include the common bell.
d. Assign the trunk to ring the hunt group containing the common bell.
Common bell control can be used with station hunt groups, individual stations and Universal Answer.
Contacts are rated at 24 VDC-1 amp.
WA R N I N G : Do not attempt to connect commercial AC power to these contacts.
