My Sliding Door Flowchart and Evaluation

This design is more complex, but I think it's safer than ones that have a motion sensor and a side ways sliding door. This design is useful for the handicapped because both doors open, so there is plenty of room for them. They don't have to press anything for the door to open, and it opens fast. It is a fast door, and no-one as to press every thing! It's safe from non-school members because to open one must have a school member card or visitor card, which must be worn around the neck. A non-school member can't just enter because a pressure pad ensures that only as many people enter as there are cards sensed. The door doesn't leave the door frame at all. When the door is fully open, it's to high for someone to hit their head on. The only problem is, if someone forgets there card, an alarm goes off for nothing. Also, someone's wheel chair or crutches might add additional pressure, so that might also cause the alarm to go off. Other than that. it's a great design!
