Collision sensor problems


Today, we tested out the collision sensor.  I parked on the loop detector and the system would have let my Dad's truck hit me.  The other day someone on there own triggered the system them self.  As soon as the dryers turned on they drove away.  The car was on the loop detector and the roller were still simulating a car.  The system shut down and needed to be powered off and back on to fix the problem.  I guess the wash link people disabled the safety feature?
