General Information
GAI-Tronics Page/Party® systems are industrial
communication systems designed to be both flexible and
durable to survive challenging industrial environments. The
9000 Series consists of a wide array of products and
configuration options that enable it to meet diverse
applications. The 9000 Series design incorporates
technologically-advanced materials to endure harsh
environments.
The Model 9974 Junction Box is packaged in glassreinforced polyester with the housing composed of two
modular subassemblies: the front panel and the rear
enclosure. This modular design allows the front panel to be
detached from the rear enclosure to simplify installation.
Mounting
1. Remove the front panel by loosening the four captive screws and swinging the panel open to the left.
Pull the hinges out of the holes in the rear enclosure to expose all four mounting holes.
2. Determine which of the four available conduit locations is to be used. Drill spots have been provided
for use with a chassis punch or hole saw. We recommend using 1.25-inch conduit hub assemblies
because this size hub will make the proper contact with the supplied grounding plate. In using any
conduit hub assembly other than the recommended size, it is the installer’s responsibility to provide
the proper earth ground bonding. Hubs must be connected to the conduit before being connected to
the enclosure.
Approved conduit entry hub assemblies:

3. There are four mounting holes in the rear enclosure. Mount the enclosure to the wall using either
four ¼-20 machine screws with nuts and washers, or #14 wood screws of appropriate length for the
mounting surface. See Figure 1. Install the rear enclosure to a wall or an appropriate surface through
the supplied mounting holes.
4. Connect the conduit to the hub assembly, and run the system cables to the unit. Follow the cable
termination instructions supplied in the “Wiring” section of this manual.

Figure 2. Wiring Diagram (Typical)
Wiring
Figure 2 is the wiring diagram for Model 9974. The wire color code is based on GAI-Tronics 60038 or
60029 inter-station cable, and 60021 speaker cable. Power connections should be made with No. 14
AWG conductors while signal connections should be made with No. 18 AWG conductors. Use of
GAI-Tronics cable, following the correct wire color designations, will ensure that power and signal
connections are made with the proper gauge wire.
NOTE: The installer must crimp a round lug onto the earth ground wire, and bolt it to the ground
stud at the top of the enclosure.
Any single screw terminal is large enough to accept up to two No. 12 AWG conductors.
