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.

CONNECTING TO A 600 OHM AUDIO PAGE PORT
OPERATING INSTRUCTIONS:
1. Pick up the telephone handset and press the CO line button (EKSU, KSU) or number assigned to paging (PBX) to access the port assigned to
paging. (Port to which the ZC-9 has been connected).
2. To initiate zone page, dial "1" thru "9" (on the telephone's touchtone keypad) to select zones 1 thru 9, respectively.
3. To initiate an All-Call page, dial "0" (on the telephone's touchtone keypad).
4. Sequential selections can be made from zone-to-zone, from All-Call to any zone, and from any zone to All-Call, by simply dialing the next digit. It
is not necessary for selections to be in numerical sequence, nor is it necessary to "hang-up" between selections.
5. When paging, background music will be muted. At the conclusion of the page (i.e., phone "hangs-up, or another selection is made), the
background music will automatically be restored.
6. When any page is initiated, an alert tone is heard both in the telephone receiver, and in all selected zones.
7. To conclude a page, simply hang-up the telephone handset.
VOLUME CONTROL ADJUSTMENT INSTRUCTIONS:
1. In the ZC-9, set the music volume control to minimum. If the system uses two central amplifiers, then set the ZC-9 music volume control midway
between minimum and maximum.
2. In the ZC-9, set the page and tone volume controls midway between minimum and maximum.
3. If the system uses speaker amplifiers and/or Wheelock Talkback Modules, then page each zone and set each speaker's volume control for the
required page level.
4. If the system uses speakers with line matching transformers, then connect the wattage selection tap on the transformer of each speaker for the
required page volume.
5. If the system uses central or zone amplifiers, then overall system or zone (as applicable) page volume can be adjusted in accordance with the
amplifier's installation instructions.
6. In the ZC-9, adjust the tone volume control to the desired level. Note the minimum setting turns the tone off.
7. In the ZC-9, adjust the music volume control for the desired background music level. If the system uses two central amplifiers, then adjust the
volume control on amplifier 2 for the desired background music level. Additional music volume adjustments can be made at the music source.
