Escape From Hell Asylum

You press some more buttons and the lights change this time. Nothing is labeled, save for an on and off switch in the far corner of the panel. There's another unmarked switch and you move it. Nothing happens for a minute, but as soon as you move to turn off the panel completely you hear a click. A metal grating falls over the reception counter. It must have been in case a patient escaped or something. You flip the switch but this time nothing happens, even after waiting for a bit.

You're trapped behind the desk now, the only way out is through the door in the back.
