INSTALLATION INSTRUCTIONS

MODEL FZC-3

FIXED ZONE CONTROL

(3 ZONES)

Use this product according to this instruction manual. Please keep this instruction manual for future reference.

1. APPLICATION INFORMATION

The FZC-3 is a Fixed Zone Control that performs the central control, switching and signaling required to provide selective Zone Paging, All Call,

Background Music Mute, Page Alert Tone Signaling and Night Ringer. The FZC-3 provides 3 separate zones of One Way paging.

The FZC-3 can also be optioned to be used with a wide variety of system amplifier configurations which can include various combinations of

25V/70V central or zone amplifiers or amplified One Way paging speakers.

The FZC-3 is compatible with most EKSU, KSU (1A2), and PBX telephone systems. It connects to either an unused loop start CO port or a 600

ohm low power audio page port. When connected to an unused CO port, DTMF telephones may be used to operate the FZC-3. When connected
to a page port, the page port must provide a dry contact closure and transmit DTMF tones. The FZC-3 can also be used in "Ring Start"
applications (Centrex, Station Level) by using a (TPI-100) telephone paging interface.

Paging is accessed from any telephone by pressing the CO line button (EKSU & KSU), or dialing the number assigned to paging. Three (3)

individual zones are selected by dialing 1,2 or 3. All Call is selected by dialing 0.

When any Zone or All Call selection is made, a page alert tone will be heard at all the speakers in the selected zone. The tone will also be heard

by the paging telephone to provide verification of connection to the selected speakers.

2. INTERFACE INFORMATION:

The FZC-3 can be connected directly to:

1. A telephone for stand alone paging.

2. A telephone system's unused CO line/trunk port.

3. A telephone system's 600 ohm audio page port (See Figure 11, page 8).

Using a TPI-100 connected to the FZC-3 then can be connected to:
(The FZC-3 should not be hooked directly to the Public Switched Telephone Network, as this can result in improper operation of the unit
and or the Public Switched Telephone Network)

1. An analog station level line.

2. A Centrex line.

3. CONFIGURATION DESCRIPTIONS

The amplifier type (central or zone) is configured as described in Chart 1.

If central amplification is used, then the choice of one or two central amplifiers is configured, as described in Chart 2.

The FZC-3 Talk Battery output or TPI-100 interface function can be selected depending upon the paging access source, as shown in Chart 3.

Amplifier Type

1. Central Amplifier:
25V or 70V audio output switched to speakers with line

matching transformers.

2. Zone Amplifier:
600 ohm audio input switched to separate zone

amplifiers connected to paging speakers with 25V/70V
line matching transformers; or switched to PRM-150
line preamplifiers or connected to amplified One Way
paging speakers.

Chart 2: 1 or 2 Central Amplifiers Configuration Function

Function Choices

1 or 2 Central Amplifiers

1. (1CA) One central amplifier for both paging and
background music. Paging in any zone will mute
music in all zones.

2. (2CA) Two central amplifiers, one for paging and
one for background music. Music is muted only in
the activated zone.

The following application diagrams show the seven basic system configurations of the FZC-3. All of these configurations are possible with the

appropriate configured switch selections. Figures 1, 2 and 3 are typical configurations using central amplifiers. Figure 4 is a typical configuration
using amplified speakers. Figures 5 and 6 are typical configurations using zone amplifiers.

One Central Amplifier which has music mute, page input and music input.

In this application, one central amplifier is used for both paging and background music. The central amplifier has music muting and separate

inputs (volume controls) for paging and music. The system uses speakers with built-in line matching transformers for paging.

1. If a stand alone telephone, unused Co Line/truckport, or 600 ohm audio page port is use connections are made directly to the FZC-3.

2. If the central amplifier does not provide music mute, then the background music source is connected as shown in Figure 2.

NOTES

If Station Level or Centrex Line a TPI-100 is required.
