General Information
Product Overview
The Model 716-102 Single Party and 7165-102
Multi-Party Flush-Mount Subsets are intended for
use in GAI-Tronics Page/Party®and SmartSeries
systems. The subset enables you to perform page
and party line communication when installed with
a remote amplifier and enclosure.
The remote subsets include a pressbar handset, a
handset cradle, and a five-party rotary selector
switch (Model 7165-102 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 subset is designed for flush-mount
applications. The integral connectorized cable
permits mounting up to eight feet from the
amplifier.
WARNING Explosion Hazard
Substitution of components may impair
suitability for Class 1, Div. 2 usage.

Description of Major Components
The Model 716-102 and 7165-102 Subsets contain external and internal components. Each major
component is described below.
External Components
The Model 716-102 and 7165-102 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 7165-102 only) is used to select the desired party line.
Magnetic hookswitch/cradle assembly provides the subset with on/off-hook control.
Subset cable is an 8-foot connectorized cable that provides connection of the subset to the Model 7245
Amplifier Enclosure.

Internal Components
The Model 716-102 and 7165-102 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 4, the handset, hookswitch, party line switch (Model 7165-102 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 5 and Figure 6 for the multi-party and single party subsets cutout details, respectively.
Drill and tap four holes in the mounting surface for No. 10-32 machine screws (included) according
to the measurements shown in to Figure 5 and Figure 6.
2. Feed the subset cable into the mounting hole.
3. Secure the subset to the mounting surface using four No. 10-32 screws and the mounting holes.
4. 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. If party line conversation is desired, rotate the selector switch to an
unoccupied party line.
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 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 limits 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.
1. Adjust the microphone gain at the remote amplifier.
2. Replace handset microphone.
Incoming conversation level
requires adjustment.
1. Adjust the receiver volume control at the remote amplifier.
2. Replace the receiver element in the handset.
Sidetone (how the operator
hears himself) requires
adjustment.
1. Adjust the receiver sidetone at the remote amplifier.
2. Check the wire terminations for proper connections in the line
balance assembly.
Feedback/distortion (a hum or
buzz on the line) occurs
during all Page/Party®station
operation.
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.
Feedback occurs during
paging.
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 worthwhile to replace the
handset/speaker amplifier PCBA.
