GENERAL APPLICATION INFORMATION:
The Telephone Paging Interface (TPI-100) provides ring start (90V/20Hz) paging access from:
A.
B.
C.
A Central Office (CO) line.
A Centrex number line.
A station level position on telephone systems which provide analog ring voltage (90V/20Hz), and 600 OHM audio to their
extension phones.
The TPI-100 is a ring detector that monitors the line for ring voltage. When ring voltage is detected, the caller is connected to
the paging system.
Paging is accomplished by touch tone (DTMF) dialing the CO line, Centrex line, or station extension number. After one ring,
the TPI-100 will simultaneously:
A.
B.
C.
Generate a single Confirmation Tone to the caller.
Generate a single Page Alert Tone to the paging system.
Connect the caller to the paging system.
The Confirmation/Page Alert Tone volume is internally adjustable, and has an "Off" position.
When a caller hangs up the telephone at the conclusion of a page, some telephone systems generate an immediate Hang Up Tone
to the paging system, some generate a delayed Hang Up Tone, while others remain silent. The TPI-100 can interface a paging
system with all of these telephone systems, because it will disconnect the paging system before the Hang Up Tone can be
transmitted over the paging system speakers.
For telephone systems that generate a delayed or immediate Hang Up Tone, the TPI-100 is equipped with a variable Frequency
Detector (200 to 950Hz) which is adjusted during installation to detect the telephone system's specific Hang Up Tone frequency.
When that frequency is detected on Tip and Ring, the TPI-100 will disconnect the paging system.
For telephone systems that generate a Hang Up Tone with a frequency that cannot be detected by the TPI-100's Frequency
Detector, or for telephone systems that do not generate a Hang Up Tone (remain silent), the TPI-100 is equipped with a variable
Page Duration Timer (3 to 51 seconds). The timer is set during installation to disconnect the paging system by:
A.
B.
Timing out before the occurrence of the Hang Up Tone or…
Simply timing out, for telephone systems that remain silent.
Whenever the Tone Frequency Detector is used:
A.
B.
It will take precedence over the Page Duration Timer.
The Page Duration Timer is placed in the maximum (51 seconds) position.
Chart 1 shows the proper application of the Tone Frequency Detector and the Page Duration Timer.

Timer Control Jumper and Tone Detect Jumper Settings
FOR ONE-WAY PAGING, The Timer Control Jumper is placed in the "VOX" position. This allows the TPI-100 to sense the
presence of audio on Tip and Ring, thereby delaying the Page Duration Timer as long as audio is present within the preset time.
If audio is not present for the preset time, then the TPI-100 will disconnect the paging system when the preset time has elapsed,
or the Hang Up Tone is detected, whichever occurs first.
FOR PAGING WITH TALKBACK, If the telephone system generates a Hang Up Tone that can be detected by the Tone
Frequency Detector, then the Timer Control Jumper is placed in the "VOX" position. This allows the TPI-100 to sense the
presence of audio, even after the caller hangs up, because the talkback speaker is still placing audio on the line. As a result, the
Page Duration Timer is continually delayed. Only the detection of the Hang Up Tone will disconnect the paging system.
If the telephone system generates a Hang Up Tone that cannot be detected by the Tone Frequency Detector, or if the telephone
system does not generate a Hang Up Tone (remains silent), then the Timer Control Jumper is placed in the "MAN" position.
The preset time is absolute, and the TPI-100 will disconnect the paging system when the preset time has elapsed.
NOTE:
Voice signals of the same frequency as the Hang Up Tone may cause the TPI-100 to disconnect. If the TPI-100 disconnects due
to the detection of voice signals, it is recommended that the Timer Control Jumper and Tone Detect Jumpers be placed using the
“Not Detectable by Frequency Detector” setting per Chart 2.
NOTE:
Telephone lines with less than -15dBM (0.1VRMS) audio level, could result in insufficient gain to operate talkback paging
systems.
MUSIC INPUT, The TPI-100 also provides a music input that is muted during a page. At the conclusion of the page, the
music is restored to the system.
TYPES OF PAGING SYSTEMS, The TPI-100 can be connected to the following types of paging systems:
A.
SINGLE ZONE PAGING:
1.
2.
3.
B.
Amplified speakers and horns for one-way paging, or...
A central paging amplifier and speakers/horns equipped with 25V/70V line matching transformers, for one-way
paging, or…
A Wheelock amplified talkback speaker (TBM-101) or horn (TBH-104) system, for paging with talkback.
MULTI ZONE PAGING:
Up to 3 zones of paging when used with Wheelock Fixed Zone Control (FZC-3).
1.
Items A1 and A2 above can be mixed in the same system.
SINGLE OR MULTIPLE LINE PAGING: The TPI-100 can be used in single line paging applications, or several can be
interconnected for multiple line paging applications.
In single line applications, a ring start line is dedicated to paging and connected to a TPI-100.
In multiple line applications, a TPI-100 and a ring start line are dedicated to each paging zone, each zone group, and "All Call"
paging. Interconnected TPI-100's automatically establish paging priorities as shown in Chart 3.

Multiple Lines
Zone and All Call Paging
Figure 5 depicts a multi zone system with "All Call". The system consists of multiple CO/Centrex or analog extension lines.
Each zone line has its own TPI-100 and page devices. An additional line and TPI-100 are dedicated to "All Call". The paging
devices connected to the TPI-100's can be any of the configurations shown in Figure 1 thru 4. The TPI-100's controlling the
individual zones should have their Timer Control Jumper programmed as described previously in Figures 1 thru 4. The TPI-100
controlling "All Call" should have its Timer Control Jumper placed in the "VOX" position. Note that single, or multiple music
sources may be used, because each TPI-100 has its own music input.
TO ACCESS AN INDIVIDUAL ZONE, dial the number of the line connected to the TPI-100 controlling that zone. An alert
tone is signaled to the zone to announce the page, and back into the phone as a confirmation tone.
TO ACCESS ALL ZONES SIMULTANEOUSLY, dial the number of the line connected to the TPI-100 controlling "All
Call". If individual zone paging is in progress when an "All Call" page is initiated, then an Alert Tone will be signaled back to
the zone paging telephones and they will be put on "Hold" for the duration of the "All Call" page. Also, a page alert tone signal
will be heard at all speakers in the system. At the conclusion of the "All Call" page, telephone still on "Hold" (did not hang up)
will receive a reconnect tone, and the interrupted zone paging will be automatically reconnected. When an "All Call" is in
progress, any attempted individual zone paging access will be prohibited, and an interrupted ringing signal (unanswered call)
will be heard in the telephone attempting to page.
When FZC-3 Units are used as page devices, the "All Call" occurs slightly different. If a FZC-3 is being accessed through an
individual TPI-100, and an "All Call" page occurs, the FZC-3 will be reset so that the incoming "All Call" may select zones.
When the "All Call" page is completed and the individual TPI-100 is reconnected, the user must re-access the original zone(s)
being paged.

Zone, Group and All Call Paging
Figure 6 depicts a multi zone system with group page and "All Call". The system consists of multiple CO/Centrex or analog
extension lines. Each zone line has its own TPI-100 and page devices. An additional line and TPI-100 is assigned to each page
group, and to "All Call". The paging devices connected to the TPI-100's can be any of the configurations shown in Figures 1
thru 4. The TPI-100's controlling the individual zones should have their Timer Control Jumper programmed as described
previously, in Figures 1 thru 4. The TPI-100's controlling group page or "All Call" should have their Timer Control Jumper
placed in the "VOX" position. Note that single or multiple music sources may be used, because each TPI-100 has its own music
input.
P82030 K
Sheet 7 of 17
There are three ways of accessing the zones with this configuration. First the zones may be accessed individually. Second, the
zones may be accessed in groups. Third, all zones can be accessed simultaneously.
TO ACCESS AN INDIVIDUAL ZONE, dial the number of the line connected to the TPI-100 controlling that zone. An alert
tone is signaled to the zone to announce the page and back into the phone as a confirmation tone.
TO ACCESS A ZONE GROUP, dial the number of the line connected to the TPI-100 controlling that zone group. An alert
tone is signaled to all zones in the group to announce the page and back into the phone as a confirmation tone. If zone paging is
in progress when a group page is initiated, then an alert tone will be signaled back to the zone page telephones and they will be
put on "Hold" for the duration of the group page. Also, a page alert tone signal will be heard at all zone speakers within the
group. At the conclusion of the group page, telephone still on "Hold" (did not hang up) will receive a reconnect tone, and the
interrupted zone paging will be automatically reconnected. When a group page is in progress, any attempted individual zone
access within the group will be prohibited and an interrupted ringing signal (unanswered call) will be heard in the telephone
attempting to page.
TO ACCESS ALL ZONES SIMULTANEOUSLY, dial the number of the line connected to the TPI-100 controlling "All
Call". An alert tone is signaled to all zones to announce the page and back into the phone as a confirmation tone. If individual
zone paging or group paging is in progress when an "All Call" page is initiated, then an alert tone will be signaled back to the
zone and/or group paging telephones and they will be put on “Hold” for the duration of the "All Call" page. Also, a page alert
tone signal will be heard at all speakers in the system. At the conclusion of the "All Call" page, telephones still on "Hold" (did
not hang up) will receive a reconnect tone, and the interrupted group, or Zone Paging will be automatically reconnected. When
an "All Call" is in progress, any attempted individual zone or group paging access will be prohibited, and an interrupted ringing
signal (unanswered call) will be heard in the telephone attempting to page.
When FZC-3 Units are used as page devices, the "Group Page" and the "All Call" occurs slightly different. If a FZC-3 is being
accessed through an individual TPI-100 and a "Group Page" or "All Call" occurs, the FZC-3 will be reset so that the incoming
"Group Page" or "All Call" may select zones. When the "Group Page" or "All Call" is completed and the individual TPI-100 is
reconnected, the user must re-access the original zone(s) being paged.

PROGRAMMING INSTRUCTIONS:
There are five parameters in the TPI-100 which must be set to insure proper operation. These are , (1) The Timer Control
Jumper, (2) The Tone Detector Jumper, (3) The Hang Up Tone Frequency Detector, (4) The Page Duration Timer, and. (5) The
Tone Alert Volume. The Timer Control Jumper and Tone Detect Jumper each have two positions. The other three parameters
are variable potentiometers.
The Timer Control Jumper is shown in Figure 11.
Figure 11.
Timer Control Jumper
When shipped from the factory, the two position jumper is placed over the two right-hand (center and "VOX") pins for voice
operated control of the Page Duration Timer. The two position jumper should be placed over the two left-hand (center and
"MAN.") pins for preset time out of the Page Duration Timer.
The Tone Detect Jumper is shown in Figure 12.
Figure 12.
Tone Detect Jumper
When shipped from the factory, the two-position jumper is placed over the two left-hand (center and “EN”) pins, enabling Hang
Up Tone detection. The two position jumper should be placed over the two right-hand (center and “DIS”) if the telephone
system does not generate a Hang Up Tone or generates a tone that cannot be detected by the Hang Up Tone Frequency Detector.
NOTE:
Voice signals of the same frequency as the Hang Up Tone may cause the TPI-100 to disconnect. If the TPI-100 disconnects due
to the detection of voice signals it recommended the Tone Detect Jumper be placed in the “DIS” position.
The Hang Up Tone Frequency Detector potentiometer is shown in Figure 13. It is used with telephone systems that generate
immediate or delayed Hang Up Tones. When it detects the Hang Up Tone, the TPI-100 will disconnect.
P82030 K
Sheet 13 of 17
Figure 13.
Hang Up Tone Frequency Detector
When shipped from the factory, the frequency is set to minimum (200Hz), and is adjustable up to 950Hz. The adjustment
procedure is as follows:
1.
Initiate a page to TPI-100.
2.
Hang up phone.
3.
When the Hang Up Tone comes on, adjust the potentiometer until the TPI-100 disconnects.
4.
Initiate a page to TPI-100
5.
Hang up phone.
6.
The TPI-100 should disconnect immediately upon detecting the Hang Up Tone. If the TPI-100 does not disconnect
immediately, repeat adjustment procedures.
The Page Duration Timer potentiometer is shown in Figure 14. It is used with telephone systems with a delayed Hang Up
Tone that cannot be detected by the frequency detector, or with systems that do not generate a Hang Up Tone (remain silent).
For telephone systems with Hang Up Tones that can be detected by the frequency detector, the Page Duration Timer (set at 51
seconds with its Timer Control Jumper in the "VOX" position) also serves as a back-up disconnect device in one-way paging
applications if the paging party inadvertently does not hang up.
Figure 14.
Page Duration Timer
When shipped from the factory the timer is set to 51 seconds (maximum). If the Timer Control Jumper is set for "VOX" control,
then the timer begins to time out when audio is no longer detected on Tip and Ring. If the Timer Control Jumper is set for
P82030 K
Sheet 14 of 17
"MAN." control, then the timer begins to time out when the page is initiated. Therefore "VOX" will provide variable duration
paging, while "MAN." will provide fixed duration paging. The adjustment procedure is as follows:
1.
If the Hang Up Tone Frequency Detector is being used to disconnect the TPI-100, then leave the Page Duration Timer set
for 51 seconds.
2.
If the Hang Up Tone Frequency Detector is not used, then proceed as follows:
A.
Using lines not connected to the TPI-100, dial station to station and have someone answer the call.
B.
Hang up phone, while the called party remains off hook (keep listening).
C.
After the caller hangs up, called party times how long it takes for the telephone system to generate its Hang Up,
"Dial" or "Reorder" tone.
D.
Set the Page Duration Timer for just under the amount of time it takes the telephone system to generate its tone. If
the telephone system does not generate a tone (remains silent), then set the timer to the desired page duration.
The Tone Alert Volume potentiometer is shown in Figure 15.
If the Hang Up Tone Frequency Detector is not used, then proceed as follows:
Figure 15.
Tone Alert Volume Control
When shipped from the factory, volume is set to maximum. To adjust the volume, initiate a page. Listen for the tone alert in the
telephone handset and at the paging speakers. If the volume is too high or too low, adjust potentiometer accordingly. The Page
Alert/Confirmation Tone can be turned off by placing the potentiometer in the "MIN." position.
OPERATING INSTRUCTIONS
P82030 K
Sheet 15 of 17
TPI-100 TELEPHONE/PAGING RING START INTERFACE
1.
Pick up the telephone handset and dial the line number assigned to the TPI-100. After one ring, the TPI-100
connects the caller to the paging system, and it will signal the caller back with a confirmation tone.
2.
If paging speakers are connected directly to the TPI-100 the caller may begin paging immediately after hearing
the confirmation tone. If a FZC-3 is connected to the TPI-100, the caller must dial a zone number after hearing
the confirmation tone. A second confirmation tone will be generated to the caller by the zone control, after
which the caller may begin paging.
3.
After the caller hangs up, the TPI-100 will disconnect when a Hang Up Tone is detected or when the Page
Duration Timer has timed out.
