Description of Major Components
These assemblies include external components accessible to the user as well as internal components or
subassemblies.
External Components
As shown from the front in Figure 1, the assembly includes a handset and cradle. When the handset is
lifted from the cradle or replaced in the cradle, a hookswitch (a magnetic reed switch) in the cradle signals
the appropriate status to the microcontroller within the assembly. To the right of the cradle the GAITronics nameplate concealing the User Level Adjustment control.

As shown from the side in Figure 2, the assembly contains the following components or subassemblies:
Chassis
Front panel affixed to the front of the chassis
Handset Amp/FSK/P PCBA (printed circuit board assembly) (Ref. 14) affixed to the rear of the
front panel
Speaker Amp/Power Supply PCBA (Ref. 13) affixed to the rear of the chassis, with a plug (P1) at the
top, pointing to the rear

The P1 connector on the back of the Speaker Amp/Power Supply PCBA plugs into a socket in an
enclosure connected to the system cable, accessing the Page/Party
®
lines and ac power. The Speaker
Amp/Power Supply PCBA contains the low voltage power supplies and the speaker amplifier circuitry.
Connector J1A and J1B on the Speaker Amp/Power Supply connects regulated +5 V dc, +/−15 V dc, and
V
voltages along with control, monitoring, and line signals to the J1A and J1B on the Handset
RLY
Amp/FSK/P PCBA. Connector J2 of the Speaker Amp/Power Supply PCBA connects to optional
external devices.
The Handset Amp/FSK/P PCBA has connections to the handset and the hookswitch via spade terminal
connectors E1 to E7, and it has connections to the optional front panel auxiliary connector, via J4.

Interfaces
The assembly interfaces to the system cable, an external loud speaker, and auxiliary devices via P1, a 16pin connector. All connections to the system cable are made by qualified installation technicians during
the system installation.
Direct questions about these connections to the GAI-Tronics Field Service Department at 800-492-1212
inside the USA or 610-777-1374 outside the USA. Other connections on the Speaker Amp/Power Supply
PCBA provide quick connect/disconnect of subassemblies.
Connector J2 on the bottom of the Speaker Amp/Power Supply PCBA connects to optional devices such
as the SmartSeries Remote Terminal Unit (RTU) installed in specially designed enclosures.
Installation
CAUTION
Do not install this equipment in hazardous areas other than those indicated
on the approval listing in the “Specifications” section of this manual. Such installation may cause a
safety hazard and consequent injury or property damage.
WARNING
Do not disconnect equipment while energized.
The SmartSeries
GAI-Tronics Page/Party
®
Model 701-905 Handset/Speaker Amplifier assembly plugs directly into any standard
®
Series enclosures. Use extra care not to damage the protruding latch wings of
connector J2 located on the bottom edge of the amplifier during installation.
®
They also plug into standard SmartSeries
enclosures such as a SmartSeries® station RTU enclosure, an
Emergency Party Line (EPL) enclosure, or an enclosure that houses a party line End-of-Line (EOL)
Module. When installing the assembly in one of these enclosures, you must also connect the
10-conductor keyed ribbon cable to J2 on the bottom of the Speaker Amp/Power Supply PCBA. Be sure
that the red line on the edge of the cable lines up with J2-pin 1.
Ensure that the connectors mate securely and then tighten the four screws in the corners of the front panel.
For continued IP 66 protection, torque setting for securing the amplifier to the enclosure should be 10 to
12 in-lbs. or 1.13 to 1.36 n-m.
