This equip ment is suitable for use in Class I, Division 2, Groups A, B, C and D or non-hazardous lo c ations only.
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.
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 sh ould not exceed 1 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 facto r .
Mounting
The 7335-001 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 receptacl e. 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 2. When mounting the enclosure, use caution to avoid damaging the
terminal blocks inside. Th e suggested mounting height for all station enclosures is 54 inches (137 cm) up to the centerline of the enclosure.
Wiring
Attach the conduit to th e enclosure. Feed the wiring through the conduit and bring it in to th e enclosure. See Figure 1. Follow the wire colors
carefully because the colors correspond to GAI-Tronics 60029 series multi-party 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 1 illustrates local speaker muting when stations are completely assembled and paging operation occurs. Normally, when the station button is
pressed, the paging speaker co nnected to that station i s 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 viol et wire attached to terminal poin t 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 ampli fier and install.
In the event that feedback occurs within an area and reposit ioni ng of the system speakers does not help, mutual muting may be used to correct this
problem. For instructions on mutually muting the station, see the complete installation, operation and maintenance manual at
