Hardware Preassembly Process
If an installation is to be preassembled, wired, programmed, and tested on
the new lightweight plastic backboard, see "Installing the Backboard."
Backboard Requirements
The backboard should be wide enough to accommodate the carrier and up to
two additional carriers, assuming that system growth is anticipated. There
should be enough room on each side of the control unit for the necessary
wiring fields.
To accommodate the maximum control unit size, make sure the backboard
meets the following requirements:
Material
— ¾-inch plywood
— Check with the local building code enforcement agency to see
whether fire-retardant material is required.
