This question has been on my mind for a while but I have never had a chance (or excuse) to ask it here.
Recently, my high school has been having problems with false fire alarms (along with an increased amount of real ones). The year alone (Since January 2014) the fire alarms has gone off almost 20 times, on average, about 5 times per month or around once to twice per week. I was wondering if this was a common thing in high school’s to have alarms go off on a weekly basis or if I am going to a high school full of arsonists. 
The reason why I bring this up is because last week the fire alarm went off everyday for three days in a row. (Multiple times per day)
(I attached incident logs as a reference)
So what is your opinion?
