If you set that off again, I'll drop a hammer on your head...

is what I wanted to say to the employees of the hospital I was working at last week. We're installing a new security system while their old one is still in place. The way the old one works is to go through the double doors that connect one part of the hospital to the other is to enter a code on a keypad before opening the door, otherwise a loud siren goes off (think car horn and louder) for about 15 seconds. For some reason, people think just because I had one door partially propped open that the alarm is disabled. Being in the business, I know how to circumvent the alarm without disabling it. Most people would ask if they have to do the code, but a few would just open the other door and go. One employee, on her third trip, I grabbed the door before she could open it and told her "No! You have to enter the code before going through".

I'm presuming there were signs up that they could ignore?

If I saw an open, alarmed door set I'd presume the alarm was disabled as well

Big red signs on each door saying it was alarmed and to go use the keypad to exit the unit.

I could understand a person going through assuming like you said that I'd disabled the alarm, but that one employee went through twice before I stopped her the third time.
