General Information
This manual applies to the GAI-Tronics 733-001 Single-Party Weatherproof Non-Metallic 120 V AC
Amplifier Enclosure, which is an important component of the 700 series Page/Party
enclosure is configured for single-party systems.
The 733-001 Enclosure is made of glass-reinforced polyester, which is extremely weatherproof and
corrosion-resistant. It is equipped with terminal strips for connecting system cable. The 701 and 751
series Amplifiers mate directly with this enclosure.

Installation
CAUTION
on the approval listing in the “Specifications” section of this manual. Such installation may cause a
safety hazard and consequent injury or property damage.
When installing an add-on station, consult the system layout diagram at the end of this manual. This
figure, when used in conjunction with the station installation information and cable layout guide, should
provide all the information necessary to install additional Page/Party< stations.
Enclosure Placement
All GAI-Tronics Page/Party® units are wired in parallel. Good system layout design minimizes the cable
required for each installation. GAI-Tronics multi-conductor cable, designed especially for this
application, is recommended. The number, size, and color-coding of conductors are listed in the
accompanying system connection diagrams.
Do not install this equipment in hazardous areas other than those indicated
System layout and power cable length are very important when installing Page/Party< equipment.
Although it varies for different systems, the general guideline is that the total power cable length should
not exceed one mile (5280 feet) for 120 V ac systems. The total cable length is the most important
consideration while cable length between the stations is generally not a factor.

Mounting
The 733-001 Enclosure is not supplied with conduit or cable openings. Drill or punch these openings
using the template supplied before mounting the enclosure. The recommended cable entry point is via
the bottom of the enclosure near the rear surface to prevent moisture from dripping onto the terminals or
PCBAs. A secondary location for cable entry is in the top of the enclosure toward the sides. Avoid the
top center, as it may interfere with the plug-in amplifier receptacle. Under no circumstances should cable
entries be made in the side of the enclosure as this may interfere with the installation of the plug-in
amplifier.
For specific details including mounting hole dimensions, refer to Figure 1. When mounting the
enclosure, use caution to avoid damaging the terminal blocks inside. The suggested mounting height for
all station enclosures is 54 inches (137 cm) up to the centerline of the enclosure.

Wiring
Attach the conduit to the enclosure. Feed the wiring through the conduit and bring it into the enclosure.
See Figure 2. Follow the wire colors carefully because the colors correspond to GAI-Tronics’ 60038
series cable. The wires must be spade-lugged and connected carefully and completely to the terminal
block. An improper termination may result in diminished station performance.
Local Muting
Figure 2 illustrates local speaker muting when stations are completely assembled and paging operation
occurs. Normally, when the station button is pressed, the paging speaker connected to that station is
silenced (muted) to prevent acoustic feedback to the handset microphone. However, while the handset is
in use for party line conversations, the paging speaker is “live” to enable paging calls from other stations.
To disable the mute feature, follow these instructions:
1. Locate the lugged violet wire attached to terminal point 7 (mute) on the terminal block within the
enclosure.
2. Transfer the lugged violet wire to terminal point 8 (Page L1).
After any muting changes are made, unpack the station amplifier and install.
Mutual Muting
In the event that feedback occurs within an area and repositioning of the system speakers does not help,
mutual muting may be used to correct this problem.
Perform the following steps to mutually mute adjacent amplifiers/handsets within a zone.
1. Ensure that the purple lugged wire is connected to terminal 7 of TB1.
2. Connect terminal TB1-7 of the handset station to TB1-7 of the station within the zone that is causing
feedback. This is done by using the spare system wire (orange conductor) from within the system
cable that runs between the stations.
