Burying the Lead

The guard holds up a hand to inspect the work order. As Sergei draws close enough to hand it to the man, the guard looks deep into the Russian's eyes as if trying to read him. He offers a wink, and nothing more.

"You know where climate control is? Straight down the hall, turn right past the labs and keep going. You'll see the maintenance door at the end. Shouldn't take too long I hope."

The guard leans back in his chair and turns his attention to his agent on which he appears to be watching soccer. Sergei notices that the guard has a large pistol on his belt and an assault rifle behind the desk. The turrets are clearly controlled by the panel of buttons his hand was over. The hallways are empty and seem to be a large square circuit that encompasses the whole floor with labs in the middle and offices on the perimeter.

Can the hallways be seen clearly from this entrance or is there a turn somewhere to block view? Also, I’m assuming cameras everywhere?

The guard tries hard not to pay attention to the hardcore flirtation from Flesher and tersely whispers,

"Go, get moving!"

The HVAC crew picks up their gear and heads down the hallway towards the indicated maintenance room. As they pass the glass wall lab they see no one inside. A great array of advanced computer equipment is arranged throughout. Just passed the lab they see the door to the maintenance room indicated by security. Inside the door is an assortment of expected janitorial equipment along with large duct work intakes, and assortment of sprinkler system shut off valves, and an electric panel that Numa thanks will likely control the camera array...

Numa opens the panel and attempts to isolate the camera lines but ends up crossing two hot wires and shorting out the fuse box. The lights go out and the emergency lights come up. You aren't sure about the state of the cameras but you do know that the black out will be noticed quickly...
