Installation
CAUTION
Do not install this equipment in hazardous areas or areas other than those
indicated on the approval listing in the Specification 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 connection diagram, Figure 7. These figures, 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 system connection
diagram.
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 1 mile (5280 feet) for 115 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 Model 703-005 Indoor RTU Enclosure is not supplied with openings for conduit or cable because their
locations vary with each installation. Drill or punch these openings using the template supplied before
mounting the enclosure.
Whenever possible, do not enter an enclosure from the top: side or bottom entry helps to prevent moisture
from dripping onto the terminals or PCBAs. The best location for conduit holes is along the bottom of the
enclosure near the rear surface. Avoid the top center, as it may interfere with the plug-in amplifier
receptacle. If the top opening must be used, carefully seal around the fitting to prevent moisture from
entering.
For specific mounting details, refer to Figure 6. There are four 0.312-inch diameter mounting holes in the
corners of the amplifier enclosure. The suggested mounting height for all station enclosures is 54 inches
(137 cm) up to the centerline of the enclosure.
