Is a 120 VAC Control Circuit in our Building from a nearby Vault considered a regular power circuit?

We have a Vault near our building that has our Irrigation Controls and Lighting Regulators that are controlled by Relay Control Panel.
We are running a 24 strand Control Cable from that Relay Control Panel in the Vault to the 2nd Floor of our Building where we have our
our Building Control Panel that allows to turn on different Lights and Sprinklers.
The Building Control Panel allows us to Switch a 120 VAC 10 A circuit that allows us to turn the Relay Control Panel in the Vault On or Off .
(See diagram, yellow highlighted area)
The 120 VAC comes from a Panel in the Vault
Presently the Cable is in a PVC jacket running through a Control Cable shaft in our Building.
However the 120 VAC control circuit has me concerned. Even though its a a Control Circuit fed from a Remote Panel it is 120 VAC 10 amps.
Should that be run in a Conduit?

it appears to me to be class 1 circuits.

725.46 Class 1 Circuit Wiring Methods.

Even though the circuit is a Control signal, the Hot side is 120 VAC and 10 Amps

Its 125 VAC and 10 A. Even though system failure will not cause a threat to life, you have that 125 VAC and 10 A ready to give somebody a Buzz. So it has to be in RMC and taken out of the PVC, right?

If this is a class 1 circuit, a chapter 3 wiring method is required. The wiring method used is based on the occupancy and uses allowed. For example EMT could be used inside but not underground.

Thank you Mr. Baker. I thought it out on the drive home. The whole 24 conductor cable needs to go into EMT.
Can't think of a way to sconvert to a 24 VDC circuit

Also, the 120 v control becomes a feeder, you will need a disconnect, grouped with service or signage so all power can be shut down.

If you look at the Diagram, the Cable actually comes close to meeting Article 727 Instrumentation Tray cable which applies to Control Circuits at 150 Volts or less and 5 amps and less. If the system was fused at 5 A vs 10, could this be true? Then all these restrictions go away

Nothing requires a class 1 circuit be low enough voltage to be nonfatal. I think they can go up to 600 V.

As another poster mentioned it needs to use an article 3 wiring method. RMC is just one such method.
