We had a fire drill at our middle school (where I am an intern) last Wednesday at 8:15 AM. Evacuation took 45 seconds, alarms sounded for about 65 seconds.
Our AHJ requires our schools to activate a different manual pull station each time. I saw the secretary pull the alarm, but the Fire-Lite MS-5210UD activated quickly enough that I didn’t have enough time to cover my ears before the Wheelock 34T (flush-mount+dual-projector) in the hallway and the AS-241575FR in our band room (which I was standing right under) began to blare in Continuous (The AS is on high volume). LOUD!!!
