Accuracy, efficiency, and reliability are key parameters of SAS Systems’ services and this is backed up by clear and accurate documentation of the installations. Schematics and layout diagrams are usually updated with cable numbers or amended using industry-standard “AutoCAD” software. Cable schedules or wirelists are prepared in “Excel” spreadsheets but we can use alternative software packages if so desired. The customer is provided with an as-built cable schedule/wirelist which is useful as a quick reference for future expansion or changes to the system.
