Installing the Control Unit

Backboard Requirements

The backboard should be wide enough to accommodate additional carriers if system growth is anticipated. In addition to the basic carrier, two expansion carriers can be added.

To accommodate the maximum control unit size, make sure the backboard meets the following requirements:

Dimensions

with SYSTIMAX wiring: 7’ W x 4’ H x 3/4” D

without SYSTIMAX wiring: 6’ W x 3’ H x 3/4” D

Material

3/4” plywood

Check with local building code enforcement agency to see if fire-retardant material is required.

Make sure that the material meets local building code requirements.

Installing the Backboard

When you are certain that the backboard and its location meet the requirements indicated in this section, attach the backboard to the wall, allowing enough room on either side of the control unit for necessary wiring fields and future addition of expansion carriers.

Use the following mounting hardware:

For a wood mounting surface, use woodscrews.

For brick, cinder block, or concrete, use masonry anchors.

For plaster or plasterboard, use toggle bolts.

For sheet-metal, use sheet-metal screws and attach them to the structural members.
