This is pretty normal, if you know there are instructed people like this guard on site. For example in our company, if there are people on shift, if the fire detector detects a fire, you have (I think) 2 minutes to reset the alarm or it goes out to the fire departement. If there is no shift, or always a hand alarm push button is pressed, the alarm goes out directly. The only thing I do not understand is, at least in our factory, you can't just reset if there is still smoke, the alarm goes of again and again and again. We would have to disable, not just reset the detector.
