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.

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 func- tion 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. To set the ZPI-4 up in the four amplifier mode: 1.

ing 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 back- ground music and it will be muted in all zones during a page. To set up the ZPI-4 in the single amplifier mode: 3.

In the two amplifier mode, one amp serves as the paging amplifier and the other as the background music ampli- fier. 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 non- paged 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 mini- mum 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.

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. 6.

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. C.

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 initiat- ed and wait for a Touch Tone entry. When it sees an entry, it activates the selected zone(s). A. Initiating a Page O Oppeerraattiioonn 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).

AApppplliiccaattiioonnss 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. A. PA-2A Paging Amplifier and Loud Ringer ? Need More Information on the PA-2A? Call (715) 386-4345 and select 485. The M15W is designed to add more paging power to almost any amplified pag- ing 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. B. M15W Paging Power Amplifier ?

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 back- ground 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. C. CPA-7B General Purpose Telecom Paging System ?
