None. Two fire alarms that I can recall. Cleveland about 18 years ago. Faulty alarm. Four am. They had been working on the system the previous day. Maintenance was on call but didn’t respond for three hours. Daytona a couple years ago. High floor. Got to the bottom of the stairwell just as the alarm stopped. Alarm started again as soon as we reached the top. Said “screw it” and went back into the room.
The 4 am alarm was the more interesting. Dead of winter. Interesting fashion show ranging from heavy robes to overcoats covering pj’s to nothing but skivvies.
