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.

Note: You must be able to send Touch Tones through the PABX’s paging port for this mode to work.
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 OFF position (all the way to the left).
Step 3. Attach a pair of wires from the paging port to the TELCO IN screw terminals.
Step 4. Attach the background music source, if required, to the MUSIC IN screw terminals.
Step 5a. If the phone system provides a page dry contact closure for paging, connect a pair of wires from this closure to
the INPUT CONTACTS screw terminals of the ZPI-4. In this application, the ZPI-4’s time out and VOX sensitivity
are disabled. The ZPI-4 will release the page port as soon as its INPUT CONTACTS open.
Step 5b. If the phone system does not provide a page dry contact closure, 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 time is reached, and if the timer is set too short, 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 periods of silence longer 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, connect a pair of
wires from the phone system night ring output to the NIGHT RING screw terminals.
Step 7. Put DIP switch 4 to OFF to disable the ZPI-4’s dial tone.
3. Paging from a Phone System’s 600 Ohm Paging Port
B. Amplifier Configuration
In this mode, each paging zone has its own amplifier, and the function of the ZPI-4 is to switch the unamplified paging or background
music signal to the appropriate amplifier.
Advantages: There is no amplifier power limitation, zones can be
set to different volumes, background music is selectable per zone
and the non-paged zones will continue to get music during a page.

In this mode, one external amplifier handles both paging and background music. An internal relay capable of switching between paging signal and music signal sends input to this amp, the amplified signal is returned and the ZPI-4
sends it to the correct zone(s).
Advantages: Any size amplifier may be used when driving 70V
speakers, only one amplifier is required.
Limitations: The amplifier needs to be limited to 200 watts, each
speaker zone is limited to an 8 ohm minimum impedance, the
amplifier must be able to drive the speakers of all zones (Example:
4 zones at 8 ohms per zone equals a 2 ohm load during an all
call); if background music is used, all zones will receive background music and it will be muted in all zones during a page.
To set up the ZPI-4 in the single amplifier mode:
3. Single Amplifier Mode
Important: If a background music amplifier is not installed and
background music is required, install the Optional Background
Music jumpers as shown above.
In the two amplifier mode, one amp serves as the paging amplifier and the other as the background music amplifier. The paging or music signal is sent to the external amplifier, returned and the amplified signal is switched by the
ZPI-4 to the correct zone or zones.
Advantages: Any size amplifier may be used when driving 70V
speakers, only (2) amplifiers (or one stereo amp) are required for 4
zones, background music is selectable per zone, and the nonpaged zones will continue to to get music during a page.
Limitations: The paging amp needs to be limited to 200 watts and
the music amp needs to be limited to 70 watts when switching 8
ohm speaker loads, each speaker zone is limited to 8 ohms minimum impedance and the amp must have the ability to drive the
speakers of all zones. (Example: 4 zones at 8 ohms per zone
equals a 2 ohm load during an all call.)
To set up the ZPI-4 in the two amplifier mode:
2. Two Amplifier Mode (Paging and Music)
Step 1. Attach the ZONE 1 screw terminals to the speaker(s) for Zone 1.
Step 2. If background music is to be enabled on this zone, ensure that the
ZONE 1 music shunts are in place, covering both pins. If background music is not desired, remove the shunts.
Step 3. Repeat steps 1 and 2 for each of the remaining three zones.
Step 4. Attach the paging amplifier and the music amplifier as shown in
the diagram.
Step 5. Set DIP switch 1 to OFF.

C. Multiple Units
While the ZPI-4 is a four zone paging unit, it may be cascaded with an additional ZPI-4 for a total of up to eight paging
zones. The first ZPI-4 is considered the “Master” unit, and the other unit is considered a “Slave”.
Diagram 11
Step 1. Install the Master unit as explained in section A. System Interface.
Step 2. Select an amplifier mode, shown in Installation section B. Amplifier Configuration, sections 1-3.
Step 3. Set DIP switch 2 to ON for both the Master and Slave. This sets both ZPI-4s for multiple units.
Step 4. On the Slave unit, set DIP switch 3 to ON. On the Master unit, leave OFF.
Step 5. If dial tone is desired, set DIP switch 4 on the Master unit to ON. This will enable dial tone for both units. On the
Slave unit, DIP switch 4 should remain OFF.
Step 6. On the Slave unit, set the RING TRIP/TRUNK/PAGE PORT switch to the same as the Master.
Step 7. On the Slave unit, set the TALK BATTERY switch to OFF.
Step 8. Connect a pair of wires from the TELCO OUT of the Master to the TELCO IN of the Slave.
Step 9. Connect a pair of wires from the MUSIC OUT of the Master to the MUSIC IN of the Slave.
Step 10. Connect a pair of wires from the OUTPUT CONTACTS of the Master to the INPUT CONTACTS of the Slave.
Step 11. If night warble is desired through the Slave’s zones, connect a pair of wires from the NIGHT RING or NIGHT
CONTACTS (depending on which application you are using) of the Master to the NIGHT RING or NIGHT CONTACTS
of the Slave.
Note: In the Trunk/Page Port mode, the Slave’s night warble volume should be set to minimum (fully counter-clock
wise). The Master’s night warble volume will control the Slave’s zones. In Ring Trip mode, the Master and Slave’s
night warble volumes will work independently.
Step 12. Set the TIME OUT ADJUSTMENT on the Slave to the maximum time (clockwise).
Step 13. Plug the power supply adapter into the power jack of the Slave, and the other end into a wall outlet.

1. Selecting Zones with One ZPI-4
B. Selecting Zones
After there has been a Touch Tone entry, the ZPI-4 activates the selected zones and produces a paging alert tone. At
this point the page can be spoken into the handset of the phone. In a RING TRIP or PAGING PORT WITHOUT CON-
TACT CLOSURE application, it is necessary to keep in mind that there is a time limit on the page, set by the TIME
OUT ADJUSTMENT. Also, in these two applications, the VOX voice detect circuit will disconnect the page if three sec-
onds of silence elapse during the page. When finished paging, simply hang up.

To page all zones, enter a Touch Tone “0”. The
ZPI-4 will activate all zones to which it is con-
nected. Otherwise, enter two Touch Tones,
with the first selecting which ZPI-4 is being
addressed, and the second selecting which
zones connected to that ZPI-4 are to be
paged. If a Touch Tone “1” is entered as the
first digit, the Master is selected. If a Touch
Tone “2” is entered as the first digit, the Slave
is selected. See diagrams to the right.
1. Ring Trip Paging
To access the ZPI-4 for ring trip paging, call the C.O., Centrex number or PABX/KSU station number the ZPI-4
is connected to. The ZPI-4 will answer on the first ring, produce dial tone (if enabled) and await Touch Tone entry
for 10 seconds. If there is a Touch Tone entry, the ZPI-4 activates the selected zone(s). If there is no Touch Tone
entry in 10 seconds, the ZPI-4 disconnects.
2. Paging from an Unused Phone System Trunk Input
To make a page with the ZPI-4 installed on a spare trunk port, simply access the trunk connected to the ZPI-4.
The ZPI-4 will produce dial tone (if enabled), wait for Touch Tone entry, and activate the selected zone(s) when it
sees a Touch Tone entry.
3. Paging from a Phone System’s 600 Ohm Paging Port
To page in this situation, access the phone system’s paging port. The ZPI-4 will detect that a page is being initiated and wait for a Touch Tone entry. When it sees an entry, it activates the selected zone(s).

Enter a single Touch Tone to select the zone
or zones to be paged. After this entry has
been made, the ZPI-4 activates the selected
zone(s). See diagram to the right.

The PA-2A provides loud ringing and paging to electronic key systems, 1A2
Key systems, PABX’s as well as No-KSU phones and multiline phones.
Paging is accomplished by connecting the PA-2A to a paging port or unused
C.O. line input of nearly any phone system.
The PA-2A will also generate an adjustable loud warble from up to 6 C.O.
lines or from a dry contact closure. An external “night transfer” switch can be
added to turn loud ringing on or off in night bell applications.
The PA-2A is easy to install and eliminates the installation of multiple bells,
relays and paging cards. The unit comes complete with a power supply,
amplifier and (1) paging horn.

The M15W is designed to add more paging power to almost any amplified paging product, or it may be used as a primary paging amplifier.
Audio can be input from a 600 ohm source or from an
8-ohm amplified source. The 15 watt output can drive
an eight to four ohm load, or two separate two-ohm
loads, which simplifies installation of up to eight 8-ohm
speakers. Installation of up to 32 speakers is possible.
A power adapter and one 25AE Paging Horn are
included.
Note: The M15W is NOT compatible with talkback
paging products such as Viking’s HF-2WC and HF-3W.

The CPA-7B is a cost effective, multi- purpose, telecom paging system.
The CPA-7B features a low noise, high fidelity amplifier, providing 6 watts of
power for a variety of telecom paging applications. It can also provide background music and night bell/common audible. In addition, multiple units may be
daisy-chained for larger paging applications.
Compatible with ringing C.O. lines, Centrex lines and
analog PABX/KSU station ports as well as unused
trunk inputs, the CPA-7B will also interface directly
with standard paging ports. The CPA-7B is easy to
install and can eliminate the installation of multiple
bells, relays and paging cards.
For loud ringing, the CPA-7B generates an adjustable loud warble from a dry contact closure,
a ringing C.O. or a ringing analog PABX/KSU station.
