Overview

Control Unit Requirements

■Dimensions

—Basic carrier: 14 in. wide by 23 in. high by 12 in. deep

—Basic carrier and one expansion carrier: 25 in. wide by 23 in. high by 12 in. deep

—Basic carrier and two expansion carriers: 37 in. wide by 23 in. high by 12 in. deep

■Location

—Within 5 ft. (152 cm) of an AC power outlet that is not

switch-controlled

—Within 25 ft. (762 cm) of the network interface, or use an Off-Premises Range Extender (OPRE)

—Within 1000 cable ft. (305 m) of telephones, or use an OPRE (for basic telephones)

! CAUTION:

The AC outlet for the control unit cannot be switch-controlled. Plugging the control unit into such an outlet invites accidental disconnection of the system.

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.
