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.

The FZC-3 can be connected to an audio page port only
(A) A 600 ohm, low power page output, capable of passing DC loop current.
(B) Transmission of DTMF touch tone.

12. NIGHT RINGER INSTALLATION INSTRUCTIONS:
The Night Ringer works from a dry contact closure through which no more than 10mA of current will be drawn. The dry contact closure will result
in the Night Ringer function, an All Call will occur and the alert tone sent out. The alert tone will remain until the dry contact closure opens. This

feature will follow the dry contact closure presented between the Night Ring and GND (TB1 Pos. 7 and 8). This feature has a lower priority than
paging. Therefore if a page comes in while the Night Ringer is active, the page will take priority.
