3.5 Installation Procedure

3.5.1 General

Installing the Searchline Excel Cross-Duct is done in two stages. First the duct is prepared, and the Excel
components mechanically fixed in place. Secondly, the electrical wiring is connected. The Transmitter and
Receiver assembly must be fully assembled and mounted to the duct structure before making the electrical
connections.

3.5.2 Mechanical Installation

Verify that the equipment to be installed is correct for the type of installation required (i.e. short or long range.)
