I had a nasty experience with these type of alarm when i was a kid. Back in September of 1993 when I was in first grade, I was attending Edgewood elementary in Fruitport, MI shortly before moving to Grand Haven. When I heard these alarms (simplex 4040 or 4050 and faraday type 2), I plugged my ears when we went into the hall to get outside. in 2006 I attended Michigan Career and Technical Institute's custodial program. They had Standard 4-350(vibratone 350) horns. When I first heard then on March 2,2006 at 8:00 PM i immediately knew what it was and ran to the nearest exit, not closing the door or grabbing my keys to the dorm. On April 10 at 9:15. I was sweeping the hall by the custodial classroom and was about 10 feet from one of the horns when they sounded for a fire drill. I said "holy ****!" and ran to the exit nearby. These things still scare me today.
