This is the main door into and out of fruit towers. And every night that I go through it I get the fear.
Press the button on the left to let yourself out. Press the one on the right to let everyone else out with you.
I've never been very good with left and right.
Update: Jen has rightly pointed out to me that this isn't a fire alarm but a clever button that keeps the door open if it needs to be kept open. I can now go through it with no fear.
