The REN is also useful to determine the quantity of devices that you may connect to your telephone line and still have all of those devices ring when your telephone number is called. In most, but not all areas, the sum of the REN's of all devices connected to one line should not exceed five (5.0). To be certain of the number of devices that you may connect to your line, you may want to contact your local telephone company.
Should the equipment cause harm to the telephone network, the telephone company shall, if possible, notify the customer that temporary discontinuance 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 operations procedures, where such action is reasonably required in the operation of its business and is not inconsistent with the rules and regulations of the Federal Communications Commission.
Do not attempt to repair or modify this equipment. Repairs to this product will be performed by Wheelock Inc. 273 Branchport Ave, Long Branch NJ 07740 in accordance with Wheelock Inc.'s published Terms and Conditions of Sale. This equipment should not be used on coin telephone lines. Connection to party line service is subject to state tariffs.
If trouble is experienced, disconnect this equipment from the telephone line to determine if it is causing the malfunction. If the equipment is determined to be malfunctioning, its use shall be discontinued until the problem has been corrected.

INSTRUCTIONS
ZONE CONTROL MODULE (9 ZONES)
MODEL NUMBER ZC-9
WARNING: ANY MATERIAL EXTRAPOLATED FROM THIS DOCUMENT OR FROM WHEELOCK MANUALS OR OTHER DOCUMENTS
The ZC-9 Zone Control Module performs the central control, switching and signaling required to provide 9 separate zones of paging, All-Call, background music mute, and page alert tone signaling.
The Zone Control can be programmed to accommodate both one-way paging and Talkback zones. It can also be programmed to provide a wide variety of system amplifier configurations which can include various combinations of 25V/70V central and zone amplifiers, amplified one-way paging speakers, and Wheelock amplified Talkback speakers.
The ZC-9 is compatible with most EKSU, KSU (1A2) and PBX telephone systems. It connects to either an unused loop start CO port of a 600 ohm low power audio page port. Note that the page port must transmit DTMF tones and must provide a dry contact closure.
Paging is accessed from any telephone by pressing the CO line button (EKSU & KSU), or dialing the number (PBX) assigned to paging. Individual zones are selected by pressing 1 thru 9 on the telephone's touchtone keypad. All Call is selected by pressing 0.
When any zone or All Call selection is made, a page alert tone will be heard at all of the speakers in the selected zone (all zones if All Call is selected). The tone will also be heard at the paging telephone to provide verification of connection to the selected speakers.
The ZC-9 is designed for use with touchtone (DTMF) systems only.

A background music input can be selectively assigned to each of the 3 zone groups.
The ZC-9 consists of 3 zone groups, as shown in CHART 1.

Each amplifier is for paging and background music in its own zone. System uses speakers with built-in line matching transformers.
Existing system renovations and expansions often require different amplifier configurations in different zone groups. For example, an existing central amplifier paging system may be zoned, and then expanded by adding amplified speakers or zone amplifiers. With the appropriate programming switch selections, the following are some examples of mixed system possibilities.
In mixed systems, the different amplifier configurations must be installed in different zone groups. It is not possible to mix different amplifier configurations within the same zone group.
The ZC-9 maximum amplifier and speaker capability for each zone and the total system is shown in CHART 6.
