You are trying to determine whether to purchase plenum or PVC cabling. Which environmental conditions should be considered before making the purchase?

a. Workstation models
b. Air duct placement
c. Floor composition
d. Window placement

Answer 1

When deciding between plenum and PVC cabling for a LAN installation, important environmental factors to consider are air duct placement, floor composition, and window placement.

Step-by-step explanation:

When deciding between plenum and PVC cabling for your LAN installation, it is important to consider the environmental conditions of the building. Three key factors to consider are:

1. Air duct placement: Determine if there are any air ducts in the building that will run above the ceiling where the cabling will be installed. If there are, plenum-rated cabling should be used as it has a special jacket that is fire-resistant and produces less toxic smoke in case of fire.
2. Floor composition: Check the type of material used for the floors in the building. If the floors are made of concrete or other non-combustible materials, PVC cabling can be used. However, if the floors are made of plenum spaces, such as drop ceilings, plenum-rated cabling should be used to comply with fire safety regulations.
3. Window placement: Evaluate the location of windows in the building. If the windows are openable and can bring in outside air, it is important to use plenum-rated cabling to prevent the spread of smoke in case of fire.

By considering these environmental conditions, you can make an informed decision on whether to purchase plenum or PVC cabling for your LAN installation.
