I once worked in a place with a keypad duress code on the security system. If you prefixed your security PIN with NN-, it was the duress version of the code and would trigger a silent alarm.
This was setup long-ago, and not communicated. One night, the keypad was acting glitchy. Partially out of frustration (countdown is running), and partially to test, I ended up accidentally engaging the duress code by tapping a convenient corner number, which resulted in NNNNNNNNN-PIN.
After law enforcement had surrounded the building, a quick chat and search alongside a few officers got it all sorted.
