Enclos ure Placement
All GAI-Tronics Page/Par t y® 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.
System layout and power cable length are important considerations when installing Page/Party
®
equipment. The rules vary for different systems, but generally, the total power cable length should not
exceed one mile (5280 feet) for 115 V ac systems. The length of cable between the stations is not a
factor; the total cable length is the most important consideration.
Mounting
Refer to Pub. 42004-185 and 42004-237 (Canada), shipped with this unit. The suggested mounting
height for all station enclosures is 54 inches (137 cm) up to the centerline of the enclosure.
To maintain the explosion-proof integrity of these stations, all mounting hardware is located outside the
enclosure. The unit should be mounted using the two mounting straps that extend past the four corners of
th e enclosure. See Figu re 1.

Use the standar d
bolts first, then the top bolts. The mounting strap design allows the station to be removed from its
mounting surface by removing only two of the bolts.
