Paging Interface

(Fax Back Document 465)

The ZPI-4 is a four-zone Touch Tone controlled paging
system capable of switching a line level signal (600
ohms) to amplifiers, 70V signal to speakers or an ampli­fied signal (200 watts maximum into 8 ohms) to speakers.

The ZPI-4 features balanced audio circuitry throughout
for low noise and compatibility with balanced paging sys­tem inputs and outputs.There are separate level controls
for paging and background music, and background music
can be disabled on a per-zone basis. Also provided is a
night bell with adjustable volume activated by a dry con-

Note: Remove these shunts to eliminate background

music for each zone individually.

IMPORTANT: Electronic devices are susceptible to lightning and power station electrical surges from both the AC outlet and the
telephone line. It is recommended that a surge protector be installed to protect against such surges. Contact Panamax at (800)

2. Paging from an Unused Phone System Trunk Input

Note: In this mode, the ZPI-4’s time out and VOX sensitivity are disabled. The ZPI-4 will release the trunk as soon

as the paging party hangs up.

Step 1. Set the RING TRIP/TRUNK/PAGE PORT switch to the RING TRIP position (all the way to the left).

Step 2. Set the TALK BATT switch to the OFF position (all the way to the left).

Step 3. Attach TIP and RING to the TELCO IN screw terminals.

Step 4. Attach the background music source, if used, to the MUSIC IN screw terminals.

Step 5. Adjust the TIME OUT ADJUST as required (adjustable from approximately 5 seconds to 80 seconds). This should

be set to a second or two longer than the longest expected page. The ZPI-4 hangs up when this timer is up, and
if the timer is set for too short a time, the ZPI-4 will hang up in the middle of a page.

Notes: The VOX SENSITIVITY probably will not have to be adjusted unless the ZPI-4 is disconnecting in the
middle of a page, before the time out or there is a period of silence during a page longer than three seconds
and the ZPI-4 does not auto-disconnect.

To adjust the VOX SENSITIVITY, turn the POT counter clockwise to decrease the VOX sensitivity and clockwise
to increase it. The VOX SENSITIVITY should be increased if the ZPI-4 is auto-disconnecting in the middle of
pages, and decreased if it is not auto-disconnecting on busy signals or periods of silence more than three seconds.

Step 6. If the phone system provides a contact closure for night ring, connect a pair of wires from this closure to the NIGHT

CONTACTS screw terminals. If the phone system provides ring signal for night ring, hook up a pair of wires from
the phone system night ring output to the NIGHT RING screw terminals.

Step 7. Select dial tone if desired by putting DIP switch 4 to ON, otherwise turn it OFF.

Step 1. Set the RING TRIP/TRUNK/PAGE PORT switch to the TRUNK/PAGE PORT position (all the way to the right).

Step 2. Set the TALK BATT switch to the ON position (all the way to the right).

Step 3. Attach TIP and RING to the TELCO IN screw terminals.

Step 4. Attach the background music source, if required, to the MUSIC IN screw terminals.

Step 5. If the phone system provides a contact closure for night ring, connect a pair of wires from this closure to the

NIGHT CONTACTS screw terminals. If the phone system provides ring signal for night ring, hook up a pair of
wires from the phone system night ring output to the NIGHT RING screw terminals.

Step 6. Dial tone may be enabled as shown in Diagram 4.
