Orion System OE742-XX-VAVZ - Manual (Page 31)

VAV/Zone Cable Length Worksheet
Project Name: _____________________________________________ Local Loop Number: ______________________
Directions: Estimate cable lengths from building mechanical plans and place in estimated cable length column beside each VAV/Zone controller or
Power/Comm board on loop. Select available cable lengths closest to estimated cable lengths and extensions for each controller or Power/Comm
board on list and place checkmarks in these columns. Also Use this information for ordering correct quantity and length of modular or digital cables and
extensions. Total each cable length column on each page and add both page totals together.

Notes:
1.)
Available Power/Comm cable lengths with the prefix “E” (E-10 Ft. or E-20 Ft.) are extensions to be used in conjunction with another standard Power/Comm cable
length to extend it to a desired length, they cannot be used by themselves without connection to a standard cable.
2.)
Available Modular Sensor cable lengths are provided in 5 Ft, 10 Ft., 25 Ft., 40 Ft. and 80 Ft. Lengths. To get longer lengths you can join 2 Modular cables together
using the MS000029 Modular Room Sensor Cable Coupler to extend the cables to a desired length in between or greater than the standard cable sizes. Available
Digital Sensor cable lengths are provided in 5 Ft., 10 Ft., 25 Ft., 40 Ft., 80 Ft., 120 Ft. and 160 Ft. sizes. You can join 2 Modular cables together using the MS000029
Modular Room Sensor Cable Coupler to extend the cables to a desired length in between the available sizes. It is recommended that you avoid this when using the
Digital Sensor cable. The maximum allowable total cable length for Digital Sensor cables is 160 Ft. and should never be exceeded.
