tern Options
‘Ihe Unisyn system offers several options that are not part of the regular installation of the common equipment. YOU
may consider an option board or a power failure station connection, for example, as a non-mandatory installation
option.The following is a list of the non-mandatory options:l
Power Failure Station(s)--Addition power fail stations are available through the use of a I’XIST Boardl
Common Audible Interface.
Auxiliary Station Interface.
External Paging Interface-Station PA PortlExternal Paging Interface-Line Port
l
Data Device (Through the TX232 Module)l Music Interface
2.7. IUnderstanding a Key System /Hybrid System
The Unisyn telephone system automatically assumes the hybrid mode whenever a programmer assigns lines to line
groups (see Section 3.6.5).The hybrid system may have a higher monthly tariff from the telephone company, so the
FCC requires that the installer report the equipment category designation number 
(KF for key system, MF for hybrid
system) to the telephone company at the time of installation.

2.7.2 Connecting A Power Failure Station
:ze .:)
The base system provides a power-fail circuit that connects the voice pair (Tip and Ring) of certain station port(s) to
the line port(s) in the event of a commercial AC power failure.You can connect an industry-standard, single-line
telephone, such as a model 
2500-xx, to the appropriate station ports and use those station(s) to provide
communications capability until the AC power to the system is restored.Connect only the voice pair (T and R) to
the IST telephone. Each TXIST board provides an additional power-fail relay (see 
IMI89-133). If you have
installed TXIST board(s), the regular Station IST device can also serve as the power-fail IST device for the
appropriate station port.
The power failure is detailed in Figure 2.7, below.
NOTE: When power is interrupted or restored, the powerfail relays will interrupt calls in progress.
Use the following chart for power-fail reference.

							ZnstallwionzM1661122.7.3 Connecting A Common Audible
And 
Auxilraty Station Interface
You can connect an external audible ringer, such as a loud bell or flashing light, that will operate when the system
receives an outside call.The contact points for this operation are dry, meaning that the external ringer or light must
have its own power supply.
There are two different ways to install an external ring indicator device.The two sets of relay closures with dry
contact points are as follows:l
One set (common audible) provides a dry-contact relay closure whenever any ofthe outside lines, connected to
the common equipment, ring.l
The other set (station 17 audible) provides a dry-contact relay closure whenever station 17 rings. You must
program the lines that you want to ring on station 17 (station 17 defaults to all lines, and you must remove the
lines that you do not want to ring the external ringer).
These contact closures track the ringing pattern in both cases.The contacts are closed during the 
ringing period and
are open during the silent period.
p?izEq
Do not exceed a load of 1 amp at 24 volts (0.5 amp at 48 volts) on these control terminals.If the load
requirements exceed this limit, connect the load through an external she relayDo not connect these control
terminals directly to the 
117vac line.
Refer to the section 2.7.5 for a discussion on using these terminals in an alternate paging function.
Contact closure connections are located as follows.l
Clip terminals 47-48 on the station connector jack J-l for Common Audible.
Clip terminals 49-50 on the station connector jack J-l for Station 17

2.7.4 Connecting An External Paging
In tetface-Sta tion PA Porf
IMI66-112
You can program any station port, except for station 10, as a PA port.
The station port that you choose thell couples
a station voice path to an external paging amplifier. You can configure the external paging amplifier so 
that an
external music source plays music over the PA. When someone wants to voice-over the music, the station 17
contact disconnects the music source and enables the voice connection. You must use station 17; no other station
port allows voice over. Refer to Chapter 3, section 3.7.19 for more information on programming a PA port.
Before
you configure a port as a PA port, consider the following:l
The audio input connection of the paging amplifier must be isolated with a 600 ohm to 600 ohm audio matching
transformer.Terminate the audio input of the paging amplifier with a 600 ohm (nominal value) resistor.l
If you program station port 17 as a PA port, the Auxiliary Station Interface (station 17 audible) contact points
are automatically re-configured as PA enable terminals.The contact closure now occurs when a user dials the
code for PA station 17. The normal auxiliary station interface function, as discussed in section 2.7.3, is disabled
as long as station 17 is a PA station.
Connect the audio input of an external paging amplifier to the audio pair of the desired station port (refer to Tables
2-2 through 2-3 for station connection details). If the paging amplifier needs to be enabled in order to function,
connect the audio input to station port 17 and the enabling leads according to the following discussion and as
illustrated below.l

2.7.5 Connecting An External Paging
Interface-Line Port
Installation
You can program a line port to be an “auxiliary port” external paging device.As an external paging port, the line
port can be used to couple a station voice path to an external paging device.Any station with that line appearance
can use the PA port simply by selecting the line.Users can dial DTMF tones or dial pulses to the external paging
device through the Auxiliary port. If users need to be able to voice-over PA music, you must connect the external
paging device to a station port as described in Section 2.7.4. For more information, see Chapter 3, Section 3.6.7.
when configuring a line port as a PA port, consider the following:l
The audio input of an external paging amplifier can be connected to the tip and ring leads of the Auxiliary port
as shown below.l
You can use DTMF tone select, zone-paging amplifier if desired. If you install this type of amplifier, users
must dial the zone-select code after pressing the paging port line select button.Program line port as
auxiliary port and connect
PA system to tip and ring
pair of that port.PA System

							InstullationZMZ66-1122.7.6 Connecting A Data Device
With the TX232 module, the system provides two RS232 Data Ports for use in connecting a data printer, personal
computer (PC), or modem for remote upload 
1 download.
Before you connect anything to a data port, consider all of
the following:l
When you use a personal computer to perform class of service programming, connect it to RS232
Data Port A (future feature).l
When you use a serial data printer for SMDR (and Caller ID, future), connect it to the RS232 Data Port B.l
The distance between the data device and the common equipment can be up to 500 feet in a quiet electrical
environment.Shielded cable may be required at some sites for long runs. For longer distances, a limited
distance modem must be used to relay the data communications between the common equipment and the data
device.
Wiring The Data Device
NOTE: You can use a commercially available straight through 9-pin cable to connect the TX?32 to a standard PC
DB9 serial port.
When preparing a cable for connection to a data device, refer to the manufacturer’s manual for the equipment being
interfaced, and make the following wiring connections:l
Wire the common equipment RD (data from device to common equipment) connection to the device TD
(transmit data) connection.l
Wire the common equipment TD (data to device from common equipment) connection to the device RD
(receive data) connection.l
Wire the common equipment SG (signal ground) connection to the device SG (signal ground) connection.l
If required for proper operation, wire the common equipment CTS (clear-to-send status from device to common
equipment) connection to the device RTS (request-to-send) connection.
NOTE: The common equipment requires a positive voltage, with respect to signal ground, in order to send data
Configuring The Data Device
The default data format is as follows.Configure the data device to match this data format for initial operation.l
8-bit data with 1 stop bit and no parityl
Baud rate of 1200 baud
