WIRING: See Figure 4.
-
Make sure the 24VDC Power Supply is disconnected from the 115VAC power source.
-
Connect Tip and Ring from telephone system to TB1, terminals 2 and 1 respectively.
-
For Zone 1, connect Speaker Amplifiers, Paging Amplifier, or Wheelock Talkback Speaker Module Tip and Ring to TB2 terminals 4 and 3
respectively. If a Talkback Speaker Module is used, also:
(A) Connect its TB inhibit (TB1 terminal 6) to the required ZC-3 zone INH (terminal 13, 14, or 15).
(B) If Talkback Module and ZC-3 use separate power supplies, then also connect Talkback Module's GND (TB1 terminal 5) to ZC-3's "A" GND
(TB1 terminal 4).
-
Connect Zone 1 background music source to TB2, terminals 1 and 2. Background music may be connected to any or all zones.
-
Zones 2 and 3 hook up in a similar fashion.
-
Connect the "A" battery power supply positive (+) and negative (-) to TB1, terminals 4 and 3 respectively. Connect the "B" battery power supply
positive (+) and negative (-) to TB1, terminals 6 and 5 respectively. One Wheelock RPS-2406 Power Supply ("A" battery) can be used for both "A"
and "B" battery.
-
Recheck all wiring.
-
Connect the power supply to the 115VAC power source.
-
Test the system using the following operation instructions.
OPERATION:
-
Pick up the telephone handset and press the CO line button (EKSU, KSU), or number assigned to paging (PABX), to access the CO port to which
ZC-3 has been connected).
-
To initiate a zone page, dial "1", "2", or "3" (on the telephone's touchtone keypad) to select zone 1, 2 or 3 respectively.
-
To initiate an All-Call page, dial "0" (on the telephone's touchtone keypad).
-
Sequential selections can be made between zones, from zones to All-Call, or from All-Call to zones by simply dialing the next zone or All-Call.
Sequential selections can be made in any order. It is not necessary to "hang-up" between selections.
-
A zone page will mute background music only in the zone selected.
-
All-Call will mute background music throughout the system.
-
At the conclusion of page (i.e., phone "hangs-up", or another selection is made), the muted background music will automatically be restored.
-
When any page is initiated, an alert tone is heard both in the telephone receiver, and at all selected speakers.
VOLUME ADJUSTMENTS:
-
First adjust volume controls on Speaker Amplifiers and Talkback Speaker Modules for required paging volume. (If paging amplifiers are used with
conventional speakers equipped with line matching transformers, then refer to the Paging Amplifier's instructions for volume adjustments).
-
Next adjust page alert tone volume (internal adjustment in ZC-3), to required level. When control is turned fully counter clockwise, page alert tone
is "OFF".
-
Lastly, adjust volume on background music source (if applicable).
