If I were to talk about all the false alarms at school this post would be a book lol
My elementary school had a old pyrotronlcs system that constantly went off. it was mostly a faulty smoke detector but once the FACP malfunctioned sending it into alarm after that it was replaced with a MS10ud because it would not reset and go into alarm when it was powerd up. then there was one actuall fire in the kitchen Times when there was an actual fire at school /work - #38 by WheelockNS the whole story is in this topic.
