GENERAL APPLICATION INFORMATION:

y

The Telephone Paging Interface (TPI-100) provides ring start (90V/20Hz) paging access from:

A. A Central Office (CO) line.
B. A Centrex number line.
C. 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. Generate a single Confirmation Tone to the caller.
B. Generate a single Page Alert Tone to the paging system.
C. 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. Timing out before the occurrence of the Hang Up Tone or…
B. Simply timing out, for telephone systems that remain silent.

Whenever the Tone Frequency Detector is used:

A. It will take precedence over the Page Duration Timer.
B. 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. Amplified speakers and horns for one-way paging, or...

2. A central paging amplifier and speakers/horns equipped with 25V/70V line matching transformers, for one-way
paging, or…

3. A Wheelock amplified talkback speaker (TBM-101) or horn (TBH-104) system, for paging with talkback.

B. 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.

Paging Priorities for Multiple Line Applications

Higher priority TPI-100's interrupt lower priority TPI-100's and place their paging on "Hold". If the interrupted paging phone
does not Hang Up, then the page will automatically be restored when the higher priority page is concluded.

The following Figures 1 thru 4 illustrate and describe single line applications.

One Zone with Talkback Paging

Figure 1 depicts a one zone system consisting of a single TPI-100 and a single TBM-101 talkback speaker system, or TBH-104
talkback horn system. One TBM-101 or TBH-104 may be used with a TPI-100. Depending upon the telephone systems Hang
Up Tone characteristics, the Timer Control Jumper can be in the "VOX" or "MAN." position. See Chart 2.

With Amplified Speakers and Horns

Figure 2 depicts a one zone system consisting of a single TPI-100 and multiple one-way paging amplified speakers/horns. If
more than three amplified speakers are used, a PRM-150 preamplifier is required to boost the audio level. The Timer Control
Jumper should be placed in the "VOX" position.

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.
