FCC REGULATIONS

This equipment complies with Part 68 of the FCC Rules. On the top of this equipment is a label that contains, among other information, the FCC

Registration Number and the Ringer Equivalence Number (REN) for this equipment. You must, upon request provide this information to your telephone

company.

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

APPLICATION INFORMATION

WARNING: ANY MATERIAL EXTRAPOLATED FROM THIS DOCUMENT OR FROM WHEELOCK MANUALS OR OTHER DOCUMENTS

DESCRIBING THE PRODUCT FOR USE IN PROMOTIONAL OR ADVERTISING CLAIMS, OR FOR ANY OTHER USE,

INCLUDING DESCRIPTION OF THE PRODUCT'S APPLICATION, OPERATION, INSTALLATION AND TESTING IS USED AT

THE SOLE RISK OF THE USER AND WHEELOCK WILL NOT HAVE ANY LIABILITY FOR SUCH USE.

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.

The ZC-9 can be connected to an audio page port only if the audio page port provides: A. A 600 ohm, low power page output, capable of passing DC loop current. B. Transmission of DTMF touchtones. C. A dry contact that is normally open, closes when paging and reopens when the page is completed. If these conditions are met, then connect Tip and Ring as shown in FIGURE 8. NOTE Check telephone system's manufacturer's installation instructions for any other audio page port connection considerations. FIGURE 8.
