General Information
Product Overview
The Model 711-102 Single Party and 7115-102
Multi-party Desk-Edge Subsets are intended for
use in GAI-Tronics Page/Party
systems.
The subset enables you to perform page and party
line communication when installed with a remote
amplifier and enclosure. The rugged remote
subsets include a pressbar handset, a handset
cradle, and a five-party rotary selector switch
(Model 7115-102 Subset only).
The subset’s compact design allows it to be
mounted where space is limited. The compact size
is made possible by housing most of the support
electronics in a separate remote amplifier.
The angle bracket, supplied with the subset,
supports a wide variety of mounting options. The
integral connectorized cable permits mounting up
to eight feet from the amplifier.

Description of Major Components
External Components
The Model 711-102 and 7115-102 Subsets contain the following subassemblies:
Pressbar handset is used to perform full-duplex party line communication. Also, one-way paging is
enabled by depressing the handset pressbar.
Party line selector switch (Model 7115-102 Subset only) is used to select the desired party line.
Magnetic hookswitch/cradle assembly provides the subset with on/off-hook control.
Mounting angle allows the subset to mounted on the left or right side of a desk.
Subset cable is an 8-foot connectorized cable that enables connection of the subset to the Model 7245
Amplifier Enclosure.

bracket)
Internal Components
The Model 711-102 and 7115-102 Subsets contain one internal component, the Subset Termination
PCBA. This assembly routes the signals of the handset, party-line selector switch, and hookswitch to the
subset cable.

Block Diagram
As shown in Figure 3, the handset, hookswitch, party line switch (Model 7115-102 only), and auxiliary
input (optional) signals connect to the Subset Termination PCBA. The Subset Termination PCBA then
connects these signals to the appropriate terminals of the subset cable for connection to the
amplifier/amplifier enclosure.

Installation
WARNING
Do not install this equipment in hazardous areas. Such installations may cause a safety hazard and
consequent injury or property damage.
1. Refer to Figure 4 for a typical desk-edge installation example.
2. Remove the mounting angle from the subset.
3. Secure the mounting angle on the mounting surface using the two screws and the 0.203 inch
(5.16 mm) mounting holes.
4. Re-connect the subset to the mounting angle with the screws provided.
5. Plug the subset cable into the amplifier enclosure and secure the connector with the connector guard
(located on the amplifier enclosure).

Operation
GAI-Tronics offers two types of Page/Party® systems: Single party with one page line and one party line,
and multi-party with one page line and five party lines allowing up to five simultaneous two-way
conversations.
For single party systems, complete the following steps to make a page announcement:
1. Lift the handset from the cradle.
2. Depress and hold the handset pressbar.
3. Speak directly into the microphone to broadcast your announcement over the loudspeakers.
4. Release the handset pressbar, and if requested, wait for a response.
The paged individual(s) responds by picking up a station handset.
For multi-party systems, complete the following steps to make a page announcement:
1. Lift the handset from the cradle.
2. If party line conversation is desired, rotate the selector switch to an unoccupied party line.
3. Depress and hold the handset pressbar.
4. Speak directly into the microphone to broadcast your announcement over the loudspeakers.
5. Release the handset pressbar, and if requested, wait for a response.
The paged individual(s) responds by picking up a station handset and turning the selector switch to the
requested party line.
With either type of system, the full duplex party line communication is not broadcast over the system
speakers. Other individuals can also pick up and join the conversation at any time. Always return the
handset to the cradle following a page or a party line conversation.

Maintenance
Adjustments
The following adjustments affecting the subsets can be made on the remote amplifier. Refer to the
applicable remote subset amplifier manual for the adjustment details.
Audio Transmit Level
The audio transmit level controls the microphone gain.
Handset Receiver Volume
The handset receiver volume controls the receiver volume level.
Other Controls
The following additional controls affect system performance; therefore, only qualified GAI-Tronics
personnel with the appropriate test equipment should make adjustments. Tampering with these controls
may void your warranty.
AGC Threshold (on SmartSeries remote amplifier only)
The control labeled AGC THRESH (on the Handset/FSK/P PCBA) sets the level at which Automatic
Gain Control (AGC) circuit begins to limit the handset microphone signals.
Sidetone Volume
The sidetone volume controls the handset sidetone (portion of the microphone audio that is fed to the
handset receiver).

Troubleshooting
The following table lists some hints to aid technicians in troubleshooting.
Problem Possible Solution
Outgoing conversation level
requires adjustment.
Incoming conversation level
requires adjustment.
Sidetone (how the operator
hears himself) requires
adjustment.
Feedback/distortion (a hum or
buzz on the line) occurs
during all Page/Party
®
station
operation.
Feedback occurs during
paging.
1. Adjust the microphone gain at the remote amplifier.
2. Replace handset microphone.
1. Adjust the receiver volume control at the remote amplifier.
2. Replace the receiver element in the handset.
1. Adjust the receiver sidetone at the remote amplifier.
2. Check the wire terminations for proper connections in the line
balance assembly.
1. Adjust the receiver sidetone at the remote amplifier.
2. The line may be improperly terminated. Inspect the system cable
for loose connections, shorts, and grounds. Line balance
assembly connections are critical.
Use the muting feature in the amplifier enclosure at the terminal
blocks as detailed in the enclosure manual.
Crosstalk occurs. One or more system cable pairs may be improperly terminated.
Visually inspect the system cable connections for accidental crossing
of the cable pairs or grounds.
Miscellaneous A defective handset/speaker amplifier printed circuit board assembly
(PCBA) can cause numerous problems. If the station is not
functioning properly, it may be necessary to replace the
handset/speaker amplifier PCBA.
