It's a little tricky.
You know how to reach the boss room?
So, when you will enter the room, keep the finger to back exactly when the doors will start to close. If you back before nothing happens, if you back after the doors close and you can't see this final in that run.

If you succeed, as soon as you come back, the stairs door will open (normally you can't open it after enter). I don't remember how long you have to back, but when you return to the stairs, they're changed, you can't go down anymore, and then, climbing, you'll face a escape exit. Just climb the (new) stairs until the end.

It's not exactly a final, but i don't read anything about the suicide attempts after entering this room: http://steamcommunity.com/sharedfiles/filedetails/?id=200679201

Narrator keeps asking you to return, you jump from the top of the stairs like 3 to 5 times and then you die.

[MPO]

Right, that would be "Narrator's Tears".

Oh, i forgot how to reach it. lol

[korren]

One time i came to the room before the monitor room by using console, but the corridor to the museum ending was closed (with bricks). Has anyone more details about this?

By the way: There is an interesting video about the buttons in the Detonation ending.

@k0rren:
That video proves the argument that players have no control at that ending, which is neat

Confused me with the "Phone" ending. I've always know it as the Apartment Ending.

yes the one that plays that amazing elevator music but it seems to go forever

I hit the button then tried to run outside but got caught on the door and couldn't move. The elevator just shakes but doesn't go up or down.

[mousemurder]

The broom closet isn't really an ending... It's more of a middle-ing
