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. For the number, size, and color-coding of conductors refer to the appropriate system
connection diagrams.
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.
Hardware Configuration
External
The multi-party enclosures each contain a handset with an approved gland, push-to-page operator, a party
line selector switch, and applicable approval labeling. The handset rests on a cradle, which has a magnetic
reed switch located behind it to signal an off-hook condition. The enclosure itself has 12 cover mounting
bolts located around the perimeter of the enclosure, and a set of aluminum hinges located on the left side.
