Low Voltage Cabling Code Help

[Hagelund]

This installation was completed recently by our local school district IT department, and sadly it seems to be typical work for them. Will someone please tell me that there is a code I can reference somewhere that I can use to stop installs from looking like this in the future?

I wonder how much they pay the beaver to gnaw those holes in the wall?

What code cycle are you on?

For LV there really are not many. As LV does not need NFPA guidelines.

In my state NFPA 70 NEC article 725 covers the install pictured.
Do the cables conductors carry power as well as data like PoE?
What type of cable is that did they leave a empty box with a sticker?
2020 NEC well, I am looking at my handy 2017 PDF that should be close;

I'd start with a few basic sections,
725.3, 725.24, 725.135, 725.144.
725.24 is a good one.
It seems exposed cable like that falls under 725.135 (K)
Once we have a cable type we might be able to narrow down 725.135 (K)

But PoE is like 5vdc?

Close PoE is more like 24V - 48V, I'd wager most is 48V, part of the concern is cable are a fuel source/vector so thats why they have sections like 725.25 and require the cables to be listed.
