Another fire alarm practice in my school! This also serves as a great test of the alarm. DO NOT do this unless you have permission from a supervisor of that building. I was fully authorized and had permission to work the school system. Thanks for watching! Never tamper with any safety equipment. I am not responsible for your actions.
