Non Plenum cable in a plenum ceiling?

[MAK]

Last week I saw a card access installation where the installer ran a non plenum cable in a conduit up and out of the electrical room above a plenum ceiling over to the door that was to have all the hardware mounted on it. The conduit was left open above the door with no means of plugging the end of the conduit. The cables then broke out to all the different devices with no conduit to encase them.The cables ran a total of maybe 8' to the devices. My question is how would this pass? I thought in a plenum ceiling that this type of cable would need to be encased all the way to the point where the cable exits the ceiling. I thought that the end of the conduit would have to be sealed up as well.

Probably done after Inspection or with no permit. I see a lot of that kind of install.

It happens in my area because we do not do low voltage inspections.

Cavie, I'm right here in south east Fla. you had better get a LV permit here.

The jurisdictions here as well.

edit to add : The ones I am aware of.

This installation was passed in the past year (so I've been told by the property manager). I was surprised because the push button that is to cut power to the mag lock does so by tripping an input on the door control module instead of looping the lock power through the button and cutting it locally.

Even if this was inspected, not all inspections involve actually looking at the cable closely enough to see that it was non-plenum. Could just be an over site on the part of the inspector.

In the past year, I have seen only one structure where the above ceiling area is being used for environmental air. I have never seen wiring in a plenum itself (other than associated wiring).

Are we certain this is not just an ordinary drop ceiling?

Yes it was a hard ceiling. I accessed it through the return air vent. The customer says the job was inspected but the workmanship is poor and it seems surprising that it would have passed an inspection.
