After Derrin presses the number-finished key, there's a five-second pause, and then his keypad flashes blue.

Keeper Derrin is as shocked as he's ever been in his life.  He lets his eyebrows go up visibly, since trying to present a perfect composure he doesn't actually possess would contradict his pride; if he wants to look that imperturbable, he needs to practice until he really is that imperturbable, not fake it.  "Checks out," he says.  "Observers, one of you go check the date of the next lunar eclipse.  There's no preset code for that scenario and you need to start emergency rupture of our causal containment if that event is less than one week away.  Also, observers, if my keypad did not just flash blue, tsi-imbi."
