of service may be required. However, where prior written notice is not possible, the telephone company may temporarily discontinue service without
notice, if such action is necessary under the circumstances. The telephone company may make changes in its communication facilities, equipment and

The ZC-312 is an expandable Zone Control that performs the central control, switching and signaling required to provide selective zone paging, zone
group paging, all call, talkback, background music mute, and page alert tone signaling. The ZC-312 provides 3 separate zones of paging, and can be
expanded to 12 zones by installing up to 3 ZEM-3 Zone Expansion Modules. Each ZEM-3 provides a zone group consisting of 3 zones. Each ZEM-3
provides a background music input for its 3 zone group.
Containing its own (centralized) talkback control circuit, the ZC-312 can be programmed to accommodate both one-way and talkback paging zones. It
can also be programmed to be used with a wide variety of system amplifier configurations which can include various combinations of 25V/70V central
and zone amplifiers and amplified one-way paging speakers.

The ZC-312 is compatible with most EKSU, KSU (1A2), and PBX telephone systems. It connects to either an unused loop start CO port or a 600 ohm
low power audio page port. When connected to an unused CO port, both DTMF and rotary (pulse) dial telephones may be used to operate the ZC-312.
When connected to a page port, the page port must transmit DTMF tones and provide a dry contact closure. The ZC-312 can also be used in "Ring
Start" applications (CO/Centrex, Station Level), when used with the Wheelock TPI-100 Telephone Paging Interface.
