So use at your own risk. I am not liable for your stupidity. Basically the blaze box activates the fire alarm switches in your school by remote control. Reasons why the box is better.
Some alarms have a hidden ink sac that squirts unwashable ink onto whoever pulls it.
If the alarm was pulled recently there might still be traces of purple ink. Servo from the car. Snow days and summer LATE nights are the best. That way if youre dumb and accidentaly set off the alarm you wont get caught. Find one of those alarm switches set into the wall.
