Confidentiality Notice
This manual is provided solely as an operation, installation, and maintenance guide and contains sensitive
business and technical information that is confidential and proprietary to GAI-Tronics. GAI-Tronics
retains all intellectual property and other rights in or to the information contained herein, and such

General Information
The Model TI984 is a telephone interface designed to
provide a communication path between the GAI-Tronics
Page/Party® industrial communication system and a public
or private telephone system.
The telephone interface allows individuals to access the
page line and the party line of the Page/Party® system
while using a standard telephone. The programming
options of this interface make the unit extremely versatile.
Because the demands on your communication system may
vary from the day shift to the night shift, this interface can
be configured for two independent sets of operating
parameters -- day mode and night mode. For example, the
method used to receive incoming telephone calls can be
configured differently for each mode.
Incoming telephone calls can access the Page/Party
system using one of four incoming access methods: voice
access, ring access, selective access, or manual access. The incoming access method that is selected
determines the way the incoming call gains access to the Page/Party® system. The telephone interface
can be configured to transfer the call directly to the designated page line or require the intervention of a
switchboard operator.
The day mode can be configured for manual access, while the night mode is configured for ring access.
Review the programming options listed in this manual to identify the optimal configuration for your
facility.
Note: The TI984 is registered with the Federal Communications Commission (FCC). As the owner of
this device, you must give the following information to the operating telephone company before
connecting or disconnecting the device:
1. Notice of your intent to use privately-owned telephone equipment.

WARNING
This equipment generates, uses, and can radiate radio frequency energy and if not installed and
used in accordance with the instruction manual, may cause interference to radio communications.
It has been tested and found to comply with the limits for a Class “A” computing device pursuant
to Subpart J or Part 15 of the FCC Rules, which are designed to provide reasonable protection
against such interference when operated in a commercial environment. Operation of the
equipment in a residential area is likely to cause interference. If interference occurs, the user, at
their own expense, will be required to take whatever measures are necessary to correct this
interference.
Installation
WARNING
This device can present a 115/230 V ac shock hazard. Please use care when handling this device.
Be sure that the ac power is not connected during wiring.
Site Requirements
The Model TI984 should be mounted near both the GAI-Tronics Page/Party® system and the RJ11C
receptacle from the telephone company or Private Branch Exchange (PBX). The distance from the TI984
to one Page/Party® station should be such that someone can adjust the controls on the TI984 while
listening to the handset of the station. The distance from the RJ11C receptacle should be less than 14
feet, to allow the use of the supplied plug-in cable.
Note: If there are no handset stations, contact the GAI-Tronics Field Service Department for instructions
at 800-492-1212, 8 a.m. to 4:30 p.m., Monday through Friday, Eastern Standard Time (EST).
The TI984 should be installed in an environment within the temperature range of 0º C to +70º C
(+32º F to +158º F).
Install the TI984 away from equipment that could cause excessive electrostatic, or electromagnetic
interference, or equipment that produces high voltage.
Wiring Instructions
1. Remove the front cover by loosening the 4 captive screws and swinging the cover open to the left.
Disconnect the ribbon cable and the telephone cable, and pull the hinges out of the holes in the rear
enclosure.
2. Determine which of the 4 available conduit locations is to be used. Drill spots have been provided for
use with either a chassis punch or hole saw.

Recommendations:
• Remove the Printed Circuit Board Assemblies (PCBAs) until installation of the conduit is
complete.
• Use 1.25-inch conduit hub assemblies because this size makes the proper contact with the supplied
grounding plate. In using a conduit hub assembly other than the recommended size, it is the
installer’s responsibility to provide the proper earth ground bonding. Hub(s) must be connected to
the conduit before being connected to the enclosure.
• The recommended hubs are: GAI-Tronics 14611-004 (1.25 inch) and Myers ST-4 (1.25 inch).
3. Install the rear enclosure on the wall using screws in the 4 corner holes. See Figure 1 for the location
of these holes.
4. Connect the conduit to the TI984, and run the wires through the conduit to connect power and signal
lines to the proper terminals as shown in Figure 2.

Figure 2. Termination Area
Telephone Line Connections
The TI984 should be connected to the Central Office (CO)
RJ11C jack from the telephone company or to a PBX with
the 14-foot RJ11 interconnect cable. See your telephone
company if a CO jack needs to be installed or extended.
The connection outlined in Figure 3 is recommended
because it allows the use of all the available types of
incoming modes. If the call from the CO is to be directly
connected to the Page/Party® system, use the bypass feature
available on the PBX.
Figure 3. Telephone Connections
Power
The unit can be powered by 115 or 230 V ac (50 to 60 Hz), or 24 V dc. If using ac power, connect the ac
neutral wire (white) to terminal 6 and the ac hot wire (black) to terminal 2. See Figure 4. The earth
ground wire (green or green/yellow stripe) should be connected to terminal 4. Set the Power Selector
switch at the lower right of the power supply to the proper voltage setting (115 or 230 V).
