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

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

the enclosure. See Figure 1.

Use the standard

-inch bolts to secure the enclosure to the mounting surface. Secure the bottom two

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.

NOTE

If this unit is to be used outdoors, it should be mounted inside a GAI-Tronics Model

10444-003 Weatherproof Non-metallic Enclosure, which is equipped with a front door. This enclosure

has four mounting feet in the four corners and is suitable for mounting to many surfaces. It can be

purchased separately.
